PART I

ITEM 1

BUSINESS

The Company

Patriot Scientific Corporation (the “Company”, “PTSC”, “we”, “us”, or “our”) has developed a number of innovative technologies throughout our history. Today we pursue two distinct technology enabled business strategies. First, we are an intellectual-property licensing company with several patents (described below) covering the design of microprocessor chips. Chips with our patented technology are used throughout the world in products ranging from computers and cameras to printers, automobiles and industrial devices. We pursue the commercialization of our patented microprocessor technologies through broad and open licensing and by litigating against those who may be infringing on our patents. Secondly, through businesses and technologies that we have acquired, we provide data sharing and secure data solutions to meet the demands of an increasingly connected world. Our integrated core intelligence solution is targeted to address the critical data/information sharing needs of the Department of Homeland Security, the Department of Justice, and federal, state, and local public safety and law enforcement agencies.

Our business address is 6183 Paseo del Norte, Suite 180, Carlsbad, California 92011; our main telephone number is (760) 547-2700. Our internet website page is located at http://www.ptsc.com. All of our reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), are available free of charge on our internet website. The information on, or that can be accessed through, our website is not part of this Annual Report.

PTSC is a corporation organized under Delaware law on March 24, 1992, and is the successor by merger to Patriot Financial Corporation, a Colorado corporation, incorporated on June 10, 1987. In June 2005, we entered into a joint venture agreement with Technology Properties Limited, Inc. (“TPL”) to form Phoenix Digital Solutions, LLC (“PDS”). During February 2007, we acquired the preferred stock of Holocom, Inc. (formerly known as Scripps Secured Data, Inc.) (“Holocom”) a company located in San Diego, California that develops and manufactures network-security hardware to government, military, and other high-security facilities. During May 2008, we acquired a minority ownership interest in Talis Data Systems, LLC (“Talis”), a Delaware LLC that produces multi-domain computer networking hardware. During the third quarter of fiscal 2010, Talis was dissolved. In September 2008, we acquired Patriot Data Solutions Group, Inc. formerly known as Crossflo Systems, Inc. (“PDSG”) our wholly-owned subsidiary engaged in data-sharing services and products primarily in the public safety/government sector. During the fiscal year 2009, we acquired preferred shares of Avot Media, Inc. (“Avot”) an innovator of video transcoding and near real-time streaming to web-enabled mobile devices. During March 2010, Avot sold substantially all of its assets.

PDSG is a segment of our business, and Holocom was a segment of our business until April 30, 2009. Refer to the Results of Operations section of Management’s Discussion and Analysis of Financial Condition and Results of Operations in this Annual Report on Form 10-K for more information as well as footnote 20 to our consolidated financial statements for more information regarding these segments.

Our Technology

General Background. Throughout our history, we have developed a number of innovative technologies for a variety of industries. We’re best known for our microprocessors, including the ShBoom, Ignite, and PSC-1000 families of chips, and for the Moore Microprocessor Patent (“MMP”) portfolio of intellectual property surrounding them. These chips and their underlying innovations were created through a combination of in-house development and acquired technology.

Industry Background. The global semiconductor (or silicon “chip”) market has many segments and categories. The best-known - and most profitable - of these is the microprocessor segment. Microprocessor chips are the “brains” of most electronic and electrical devices throughout the world. Although microprocessors are often closely associated with personal computers (“PCs”), PCs account for only about 2% of the microprocessor chips made and sold every year. The vast majority of microprocessors are used in everyday items like automobiles, digital cameras, cell phones, video game players, data networks, industrial flow-control valves, sensors, medical devices, weapons, home appliances, robots, security systems, televisions, and much more. These “embedded microprocessors” (so called because they’re embedded into another product) are far more ubiquitous than the chips inside personal computers. This is the market that our technology serves.

Patent Description. Over the years we’ve developed a number of innovative technologies that have been embodied in our own products and, through licensing, into other companies’ products. Many of these patented technologies are available under the MMP portfolio. The MMP portfolio includes several U.S. patents as well as their European and Japanese counterparts. Some highlights of the patent portfolio are:

●

US 5,809,336 (the “’336 patent”). The ’336 patent covers an early and seminal approach to making microprocessor chips go faster. It allows the “core” of the microprocessor to run at a different speed (usually faster) than the rest of the chip. There are many advantages to this, including higher performance, lower power consumption, and simpler manufacturing.

●

US 5,784,584 (the “’584 patent”). The ’584 patent covers an important method for a microprocessor chip to fetch multiple instructions at once. Like speed reading, multiple-instruction fetch allows a chip to get more done in less time - a valuable technique.

●

US 6,598,148 (the “’148 patent). The ’148 patent describes on-chip oscillators (clocks) and covers multi-core and multi-processor implementations - important factors in today’s high-end microprocessor chips.

Our Partners and Affiliates

Phoenix Digital Solutions, LLC. On June 7, 2005, we entered into a Master Agreement (the “Master Agreement”) with Technology Properties Limited, Inc. (“TPL”), and Charles H. Moore, an individual (“Moore”). We, TPL and Moore were parties to certain lawsuits filed by us alleging infringement (the “Infringement Litigation”) of the seven U.S. patents issued dating back to 1989 on our microprocessor technology (the “Microprocessor Patents”) and a lawsuit also filed by us alleging claims for declaratory judgment for determination and correction of inventorship of the Microprocessor Patents (the “Inventorship Litigation”). The transactions described in the Master Agreement and related agreements (the “Transactions”) included the settlement or dismissal of the Inventorship Litigation.

Pursuant to the Master Agreement we agreed with TPL and Moore as follows:

●

We entered into a patent license agreement (the “Intel License”) with Intel Corporation (“Intel”) pursuant to which we licensed certain rights in the Microprocessor Patents to Intel.

●

We entered into an Escrow Agreement along with TPL (the “Escrow Agreement”) pursuant to which the proceeds arising from the Intel License were allocated for the benefit of us and TPL. Pursuant to the Escrow Agreement, the proceeds were allocable equally to PTSC and TPL. Accordingly, when the initial capitalization obligations of PTSC and those of TPL with regard to PDS (defined below) were satisfied, and when our payment obligations and those of TPL with regard to the Rights Holders (defined below) were made, we received $6,672,349, and the remaining proceeds were allocated to or for the benefit of TPL.

●

We caused certain of our respective interests in the Microprocessor Patents to be licensed to PDS, a limited liability company owned 50% by us and 50% by TPL.

●

PDS engaged TPL to commercialize the Microprocessor Patents pursuant to a Commercialization Agreement among PDS, TPL and us (the “Commercialization Agreement”).

●

We paid $1,327,651 and TPL paid $1,000,000 to certain holders of rights in the Microprocessor Patents (“Rights Holders”) in exchange for the release of such Rights Holders in connection with the Transactions.

●

We agreed with TPL and Moore to settle or cause to be dismissed all litigation involving the Microprocessor Patents, pursuant to a stipulated final judgment, including the Inventorship Litigation.

●

We issued warrants to TPL which were exercised by TPL in September 2007, to acquire shares of our common stock, $0.00001 par value (“Common Stock”). 1,400,000 warrants were exercisable upon issue; 700,000 warrants became exercisable when our Common Stock traded at $0.50 per share; an additional 700,000 warrants became exercisable when our Common Stock traded at $0.75 per share; and an additional 700,000 warrants became exercisable when our Common Stock traded at $1.00 per share, all such vesting having been achieved as of the date of this filing.

●

We agreed with TPL and Moore to indemnify each other for, among other things, any inaccuracy or misrepresentation in any representation or warranty contained in the Master Agreement, any breach of the Master Agreement, certain liabilities relating to the respective interests of each of us in the Microprocessor Patents and the Transactions, and certain tax liabilities.

Pursuant to the Commercialization Agreement, PDS granted to TPL the exclusive right to grant licenses and sub-licenses of the Microprocessor Patents and to pursue claims against violators of the Microprocessor Patents, in each case, on behalf of PDS, us, TPL and Moore, and TPL agreed to use reasonable best efforts to commercialize the Microprocessor Patents in accordance with a mutually agreed business plan. Pursuant to the Commercialization Agreement, PDS agreed to a reimbursement policy with regard to TPL’s expenses incurred in connection with the commercialization of the Microprocessor Patents. All proceeds generated by TPL in connection with the commercialization of the Microprocessor Patents are paid directly to PDS. From the inception of the Commercialization Agreement to May 31, 2010, gross license revenues to PDS totaled $273,833,235.

Pursuant to the Master Agreement, we and TPL have entered into the Limited Liability Company Operating Agreement of PDS (“LLC Agreement”). We and TPL each own 50% of the membership interests of PDS, and each have the right to appoint one member of the three (3) member management committee. The two (2) appointees are required to select a mutually acceptable third member of the management committee. Pursuant to the LLC Agreement, we and TPL must each contribute to the working capital of PDS (in addition to the Microprocessor Patent licenses described above), and are obligated to make future contributions in equal amounts in order to maintain a working capital fund. The LLC Agreement provides that PDS shall indemnify its members, managers, officers and employees, to the fullest extent permitted by applicable law, for any liabilities incurred as a result of their involvement with PDS, if the person seeking indemnification acted in good faith and in a manner reasonably believed to be in the best interest of PDS.

In April 2010, we filed actions against TPL for default on their note receivable with us and for breach of the Commercialization Agreement. See Part 1, Item 3. “Legal Proceedings” in this Annual Report for more information.

Holocom, Inc. (formerly known as Scripps Secured Data, Inc). On March 27, 2007, we entered into a revolving line of credit with Holocom, a company that manufactures products that protect information and data transmitted over secured networks. Previously, we maintained an unconsolidated equity investment in Holocom. We determined that the line of credit transaction caused us to become the primary beneficiary under the Financial Accounting Standards Board’s (“FASB”) authoritative guidance for consolidation of variable interest entities and as such we were required to consolidate variable interest entities for which we are deemed to be the primary beneficiary. On August 29, 2008 Holocom paid us $75,000, the remaining balance due on the line of credit and provided us notice effectively terminating the line of credit on August 29, 2008.

During July 2008, Holocom obtained a credit facility for up to $300,000 from a third party, the credit facility term extended to May 1, 2009, and was guaranteed by us. As a result of our guarantee on the third party credit facility, we maintained a variable interest in Holocom. Upon expiration of the credit facility on May 1, 2009 we deconsolidated Holocom as we were no longer deemed to be the primary beneficiary.

Management has determined that the inability of Holocom to meet its business plan, raise capital, and the general economic environment are indicators of impairment on our investment. Accordingly, at May 31, 2010, we wrote off our investment in the preferred stock of Holocom, amounting to a $435,182 write off.

Holocom was an operating segment of our business for the periods in which we were required to consolidate (March 27, 2007 through April 30, 2009). Refer to footnote 20 of our consolidated financial statements for disclosures about this operating segment.

Talis Data Systems, LLC. On May 16, 2008 we acquired a 15.09% equity share in Talis, a company that produced multi-domain computer and network security products for sale to government, military, and enterprise customers. Talis developed and marketed PCs incorporating its Datagent security device, a patented, hardware based data security solution that avoided the vulnerability of software–based approaches.

Throughout fiscal 2009 and during the first quarter of fiscal 2010, we increased our equity investment in Talis to 39.4% as a result of purchasing additional membership units offered by Talis, as well as acquiring membership units from minority members which included the acquisition of all Talis membership units previously held by Holocom. The acquisition of Talis membership units previously owned by Holocom was made for $100,000 in cash and a reduction on their outstanding line of credit of $219,000.

The inability of Talis to meet its business plan, raise capital, and the general economic environment were indicators of impairment on our investment. Accordingly at August 31, 2009, management determined that our investment in Talis was impaired by approximately $680,000. During the third quarter of fiscal 2010 Talis was dissolved.

Avot Media, Inc. Avot was an innovator of video transcoding and near real-time streaming to web-enabled mobile devices. During the quarter ended August 31, 2008, we invested an aggregate of $1,300,000, including conversion of a note receivable in the amount of $250,000, to obtain 14,444,444 shares of Series B preferred stock issued by Avot, representing 53.3% of the Series B preferred stock and 37.1% of all Avot’s preferred shares issued and outstanding. On March 12, 2009, we entered into a secured revolving loan note with Avot for $500,000. The note bore interest at a rate of 8% and was due December 12, 2009. During fiscal 2009 and 2010 we wrote off our investment in Avot as management determined that our investment was impaired due to Avot’s inability to meet its business plan, to raise capital, and the general economic environment. During March 2010, Avot sold substantially all of its assets and we collected our $500,000 note.

Licenses, Patents, Trade Secrets and Other Proprietary Rights

We rely on a combination of patents, copyright and trademark laws, trade secrets, software security measures, license agreements and nondisclosure agreements to protect our proprietary technologies. Our policy is to seek the issuance of patents that we consider important to our business to protect inventions and technology that support our microprocessor technology and other lines of business.

We have seven U.S. patents issued dating back to 1989 on our microprocessor technology. We have one microprocessor technology patent issued in five European countries and one patent issued in Japan. These patents in the U.S and overseas are currently set to expire between 2012 and 2015. We may file additional applications under international treaties depending on an evaluation of the costs and anticipated benefits that may be obtained by expanding possible patent coverage. In addition, we have one U.S. patent issued on ground-penetrating radar technology and one U.S. patent issued on one of the communications products.

In addition to such factors as innovation, technological expertise and experienced personnel, we believe that a strong patent position is becoming increasingly important to compete effectively in the semiconductor industry. It may become necessary or desirable in the future for us to obtain patent and technology licenses from other companies relating to technology that may be employed in future products or processes. To date, we have not received notices of claimed infringement of patents based on our existing processes or products but, due to the nature of the industry, we may receive such claims in the future.

We have one U.S. patent on our ground-penetrating radar technology, which is currently set to expire in 2011. No foreign application has been made. There are a large number of patents owned by others in the radar field generally and in the field of ground-penetrating radar specifically. Accordingly, although we are not aware of any possible infringement and have not received any notices of claimed infringement, we may receive such claims in the future.

In November, 2004, we filed a patent application for “Remote Power Charging of Electronic Devices” with assignment to Patriot Scientific Corporation.

During fiscal 2009, we finalized an agreement with NuPower Semiconductor whereby we became co-assignees of a total of seven U.S. patents (five of which had issued and two of which had notices of allowance) related to power management for microprocessor based systems. The agreement is effective until November 30, 2010. The assignment was final in fiscal 2010 with the United States Patent and Trademark Office (“USPTO”) following the final issuance of the remaining two patents. These patents are currently set to expire between 2026 and 2029.

There can be no assurance that any patents will be issued from pending or future applications or that any patents that are issued will provide meaningful protection or other commercial advantages to us. Although we intend to protect our rights vigorously, there can be no assurance that these measures will be successful.

We generally require all of our employees and consultants, including our management, to sign a non-disclosure and invention assignment agreement upon employment with us.

Research and Development

During fiscal years 2010 and 2009, we incurred $1,503,724 and $510,848, respectively, of research and development expenses related to PDSG technologies. We did not incur research and development expenditures for the fiscal year ended May 31, 2008.

Products and Services

The following technologies comprise the PDSG family of products:

Crossflo DataExchange® Our technology, Crossflo DataExchange® (“CDX”), was developed to exchange data between a customer’s application or database and an XML schema such as NIEM, Universal Core (U-CORE), CAP, GJXDM, or HL7. CDX can use any XML schema or even create a new schema specific to a customer’s needs. Whether the system is a source of data, a target for data, or both, it is “mapped” to the designated XML schema, and the subsequent exchange of data follows this common schema. This loosely coupled approach is easy to implement and maintain and can be accomplished with personnel who are not IT experts. Data exchange can begin in a matter of days or weeks, versus the months or even years that may be required using other solutions. Of particular significance is that this approach makes sharing data invisible to the end users by eliminating operational change and disturbance while utilizing existing infrastructure.

CDX is accessed via a web-based interface used to define publications (sources) and subscriptions (targets), and includes a powerful data-transformation mapper. The mapper offers an intuitive "drag and drop" interface, a rich set of transformation objects, and the ability to connect to web services. It also possesses powerful features for exporting data in the appropriate form to be used immediately by other applications including Geospatial Information System (GIS) programs, intelligence analysis programs, emergency management applications, and case management systems. Further, CDX handles complex schema constructs with ease and supports federated, scheduled, and triggered message exchanges.

CDX was designed and built using the latest standards-based technologies resulting in flexibility and cost savings. For example, because our software is written in JAVA/J2EE, it runs on virtually any platform and operating system. It incorporates Service Oriented Architecture and Web Services so it is easy to access and modify. CDX eliminates the need to make any changes to existing applications, procedures, and databases. Designed and developed in the US by US citizens with deep and targeted domain expertise, strong security measures have been integrated into the technology.

Information exchanges utilizing CDX can easily be implemented in a staged manner in virtually any environment regardless of future technological or infrastructure unknowns, enabling quick and early wins to build confidence and momentum. CDX provides a rapidly deployable, scalable, effective, and affordable means to enable the immediate sharing, integration, and/or aggregation of appropriate data assets across virtually all enterprises, platforms, vendors, and locations. In addition, CDX is compatible with other middleware products and can be implemented using an existing customer-provided Enterprise Service Bus (ESB).

In March 2010 a re-architected version of CDX was completed (CDX 4). Significant additions include the CDX ExchangeBuilder, which is designed to generate National Information Exchange Model (NIEM) conforming Information Exchange Package Documents (IEPDs), significantly reducing the cost and time it takes to specify and deploy standards-based data exchanges. CDX 4 includes the CDX Portal, a secure, end-user interface designed for justice personnel. Built on the Global Federated Identity and Privilege Management (GFIPM) framework, the CDX Portal enables agencies to control and manage access to an exchange’s applications and data services. These data services can include federated queries of information residing in disparate data sources integrated by CDX, or services hosted by third party applications already owned by agencies. The Crossflo DataExchange® is a fully integrated suite of tools, but customers can decide if and when they wish to add individual modules, so an affordable solution can be configured for each client’s specific needs. This will enable agencies of different sizes, with different resources, to choose between a tool such as CDX ExchangeBuilder to design IEPDs, a CDX DataExchange base package for a standard exchange, or a CDX DataExchange enterprise solution to enable large scale exchanges incorporating CDX Portal and multiple data services.

Vigilys Commander™, Vigilys Mobile™. Vigilys is a Tactical Operations System that bridges the information gap among field personnel and the operations center. Critical decisions impacting loss of life and property damage are made in the field during the first minutes of an incident. It is imperative for comprehensive, immediate, actionable, and relevant information to be delivered to and from the field during that critical time period for better decision-making, resource allocation and mission execution. Vigilys orchestrates and delivers real-time, incident-specific information graphically during those first few minutes, and as an incident unfolds, for improved situational awareness and response. Through its service oriented architecture and automated business processes, Vigilys presents information in a geospatial Tactical Common Operating Picture (“TCOP”), and provides tactical tools for dynamic updates. As the TCOP is updated, this information is shared in real-time among authorized users for collaboration and resource management. The TCOP provides a visualization layer of the incident action plan based on inputs from field responders as well as from data collected from CDX. Vigilys can deliver the TCOP to authorized users via a web browser, and on touch screen enabled mobile or laptop computers. This combination of data mediation and real-time, map-based display provides a new level of situational awareness to first responders and emergency managers. On August 1, 2010, we sold the Vigilys technology. See footnote 21 to our consolidated financial statements for more information.

Sales and Marketing

During the fiscal year ended May 31, 2009, we sold the remainder of our microprocessor chip inventory. We did not actively market the microprocessor chips in our Ignite product line. All of our sales for fiscal years ended May 31, 2010 and 2009 and 2008 were to domestic customers with the exception of PDSG which has a CDX hosting arrangement with a customer in Japan.

PDSG markets its products and services to domestic federal and state governmental agencies through direct contracts and via partnerships with prime contractors. During fiscal year 2009, PDSG was awarded a United States General Services Administration Schedule Information Technology contract to offer selected products and services including its CDX software solution.

All of our operating assets are located within the United States. While sales to certain geographic areas generally vary from year to year, we do not expect that changes in the geographic composition of sales will materially affect our operations.

Dependence Upon Single Customers

Ten percent (10%) or more of our consolidated product sales were derived from shipments to the following Holocom customers for the fiscal years ended May 31 as follows:

	2009		2008
Customer A	$	1,907,499	$	1,354,494
Customer B	$	706,553	$	889,724
Customer C		-	$	370,301
Customer D	$	1,091,467		-

Ten percent (10%) or more of our consolidated license and service revenues were derived from sales to the following PDSG customers for the fiscal year ended May 31 as follows:

	2010
Customer A	$	281,141
Customer B	$	106,064

We had no backlog orders as of May 31, 2009 or 2008. As of May 31, 2010, our backlog is $268,103 which consists of contracts executed with customers during the current fiscal year which will not be completed by May 31, 2010.

Most of our net income for the years ended May 31, 2010, 2009 and 2008, was attributable to our equity in the earnings of our unconsolidated affiliate, PDS.

Government Regulation and Environmental Compliance

We believe our products are not subject to regulation by any federal, state or local agencies that would materially affect the manufacture, sale or use of our products, other than occupational health and safety laws and labor laws which are generally applicable to most companies. We do not know what sort of regulations of this type may be imposed in the future, but we do not anticipate any unusual difficulties in complying with governmental regulations which may be adopted in the future.

We have not incurred any material costs associated with compliance with environmental laws and do not anticipate such laws will have any material effect on our future business.

Employees

At May 31, 2010, we have seventeen employees. All employees are full time. We also engage consultants and part-time persons, as needed.

Our future success depends in significant part upon the continued services of our key technical and senior management personnel. The competition for highly qualified personnel is intense, and there can be no assurance that we will be able to retain our key managerial and technical employees or that we will be able to attract and retain additional highly qualified technical and managerial personnel in the future. None of our employees are represented by a labor union, and we consider our relations with our employees to be good. None of our employees are covered by key man life insurance policies.

Available Information

We file annual, quarterly and special reports, proxy statements and other information with the Securities and Exchange Commission (“SEC”). Materials filed with the SEC can be read and copied at the SEC’s Public Reference Room at 100 F Street, NE, Washington, DC 20549, on official business days during the hours of 10 a.m. to 3 p.m. Information on the operation of the Public Reference Room may be obtained by calling the SEC at 1-800-SEC-0330. The SEC maintains an Internet web site that contains reports, proxy and information statements and other information regarding issuers that file electronically with the SEC. Our filings are available to the public at the website maintained by the SEC, http://www.sec.gov. We also make available, free of charge, through our web site at www.ptsc.com, our reports on Forms 10-K, 10-Q, and 8-K, and amendments to those reports, as soon as reasonably practicable after they are filed with or furnished to the SEC. The information on, or that can be accessed through, our website is not part of this Annual Report.

ITEM 1A.

RISK FACTORS

We urge you to carefully consider the following discussion of risks as well as other information contained in this Form 10-K. We believe the following to be our most significant risk factors as of the date this report is being filed. The risks and uncertainties described below are not the only ones we face.

We Have Initiated Legal Proceedings Against Our Joint Venture Partner Which Could Adversely Affect Our Relationship With Them And Our Receipt Of Licensing Revenues.

Under our joint venture arrangement with TPL, TPL is responsible for the licensing and enforcement of our microprocessor patent portfolio. In April 2010 we filed two actions against TPL (and with respect to one action, another defendant) alleging breach of a $1 million promissory note issued to us by TPL and other causes of action, as more particularly described below under Part I, Item 3. "Legal Proceedings" in this Annual Report. Because we are wholly dependent on TPL to secure licensing revenues with respect to our microprocessor patent portfolio, which revenues have represented substantially all of our income since June 2005, the commencement of these adversarial proceedings against TPL could have an adverse affect on our continued relationship with TPL and its ability to effectively negotiate licenses or enforce our rights with respect to our microprocessor patent portfolio, which in turn could adversely affect our revenues and financial condition.

We Have Reported Licensing Income For The Fiscal Years 2010, 2009 And 2008 Which May Not Be Indicative Of Our Future Income.

We have entered into license agreements through our joint venture with TPL and have reported licensing income as a result of this activity for the fiscal years 2010, 2009 and 2008. Because of the uncertain nature of the negotiations that lead to license revenues, pending litigation with companies which we allege have infringed on our patent portfolio, the possibility of legislative action regarding patent rights, potential adverse outcomes associated with USPTO re-examinations, and the possible effect of new judicial interpretations of patent laws, we may not receive revenues from such agreements in the future consistent with amounts received in the past, and we may not receive future revenues from license agreements at all.

We Are Dependent Upon A Joint Venture In Which Our Role Is Of A Passive Nature For Substantially All Of Our Income.

In June 2005, we entered into a joint venture with TPL, pursuant to which TPL is responsible for the licensing and enforcement of our microprocessor patent portfolio. This joint venture has been the source of substantially all of our income since June 2005. Therefore, in light of the absence of significant revenue from other sources, we should be regarded as entirely dependent on the success or failure of the licensing and prosecution efforts of TPL on behalf of the joint venture, and the ability of TPL to obtain capital when necessary to fund its operations. In December 2009 and January 2010, we provided operational funding by loaning TPL $950,000 and $1,000,000, respectively. The $1,000,000 note which was due to be repaid by February 28, 2010 is currently in default, and we have provided a full allowance against this receivable. On July 15, 2010, we received $1,003,095 from PDS for payment on the $950,000 note issued in December 2009. We do not anticipate making additional loans to TPL, and its ability to access liquidity from other sources is not certain. See Part 1, Item 3. “Legal Proceedings” in this Annual Report for more information.

A Successful Challenge To Our Intellectual Property Rights Could Have A Significant And Adverse Effect On Us.

A successful challenge to our ownership of our technology or the proprietary nature of our intellectual property could materially damage our business prospects. We rely on a combination of patents, trademarks, copyrights, trade secret laws, confidentiality procedures and licensing arrangements to protect our intellectual property rights. With respect to our core technologies, we currently have seven U.S. patents, one European patent, and one Japanese patent issued. Any issued patent may be challenged and invalidated. Patents may not be issued for any of our pending applications. Any claims allowed from existing or pending patents may not be of sufficient scope or strength to provide significant protection for our products. Patents may not be issued in all countries where our products can be sold so as to provide meaningful protection or any commercial advantage to us. Our competitors may also be able to design around our patents.

Vigorous protection and pursuit of intellectual property rights or positions characterize the fiercely competitive semiconductor industry, which has resulted in significant and often protracted and expensive litigation. Therefore, our competitors and others may assert that our technologies or products infringe on their patents or proprietary rights. Persons we believe are infringing our patents are likely to vigorously defend their actions and assert that our patents are invalid. Problems with patents or other rights could result in significant costs, limit future license revenue, and impair or hinder our acquisition strategy. If infringement claims against us are deemed valid or if our infringement claims are successfully opposed, we may not be able to obtain appropriate licenses on acceptable terms or at all. Litigation could be costly and time-consuming but may be necessary to protect our future patent and/or technology license positions or to defend against infringement claims. From time to time parties have petitioned the U. S. Patent and Trademark Office to re-examine certain of our patents. An adverse decision in litigation or in the re-examination process could have a very significant and adverse effect on our business.

We have been named as co-defendants in multiple lawsuits regarding the MMP Portfolio. See footnote 19 to our consolidated financial statements and Part I, Item 3. “Legal Proceedings” in this Report on Form 10-K for more information.

Disruptions In The Debt And Equity Markets Will Have An Adverse Affect On Our Ability To Obtain Funding.

The debt and equity markets have been experiencing volatility and disruption for several fiscal periods. These issues, along with significant write-offs in the financial services sector, the re-pricing of credit risk, and the current weak economic conditions have made, and will likely continue to make, it difficult to obtain funding. The cost of accessing the credit markets has increased as many lenders and institutional investors have increased interest rates, enacted tighter lending standards, and reduced or ceased to provide funding to borrowers. Adverse changes in the economy could limit our ability to obtain financing from debt or equity sources or could adversely affect the terms on which we may be able to obtain any such financing for our operating activities See Part II – Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations-Liquidity and Capital Resources-Liquidity.” in this report on Form 10-K for more information.

Unstable Market And Economic Conditions May Have Serious Adverse Consequences On Our Business.

Our general business strategy may be adversely affected by the economic downturn and volatile business environment and continued unpredictable and unstable market conditions. A prolonged or profound economic downturn may result in adverse changes to our sales and pricing, which would harm our operating results. Failure to secure any necessary financing in a timely manner and on favorable terms could have a material adverse effect on our growth strategy, financial performance and stock price and could require us to delay or abandon development plans. There is also a possibility that our stock price may decline further, due in part to the volatility of the stock market and the general economic downturn.

Changes In Our Relationships With Companies In Which We Hold Less Than A Majority Interest Could Change The Way We Account For Such Interests In The Future.

For our investment accounted for under the equity method (PDS), we record as part of other income or expense our share of the increase or decrease in the equity of this company in which we have invested. Prior to the impairment, we accounted for our investment in Holocom on the cost basis. It is possible that, in the future, our relationships and/or our interests in or with this equity method investee and our cost basis investee could change. Such potential future changes could result in deconsolidation or consolidation of such entities, as the case may be, which could result in changes in our reported results.

Exercise Of Warrants And Options May Have A Substantial Dilutive Effect On Our Common Stock.

If the current per share market price of our Common Stock at the time of exercise of any warrants or stock options is in excess of the various exercise prices of such securities, exercise of such securities would have a dilutive effect on our Common Stock. As of May 31, 2010, holders of our outstanding exercisable warrants and options would receive 5,325,108 shares of our Common Stock, absent any cashless exercise, at a weighted average exercise price of $0.46 per share. Any additional financing that we secure likely will require that we grant rights senior to those of our Common Stock which may result in substantial dilution of the existing ownership interests of our common stockholders.

We May Issue Preferred Stock, And The Terms Of Such Preferred Stock May Reduce The Value Of Our Common Stock.

We are authorized to issue up to a total of 5,000,000 shares of preferred stock in one or more series. Our Board of Directors may determine whether to issue shares of preferred stock without further action by holders of our Common Stock. If we issue shares of preferred stock, it could affect the rights or reduce the value of our Common Stock. In particular, specific rights granted to future holders of preferred stock could be used to restrict our ability to merge with or sell our assets to a third party. These terms may include voting rights, preferences as to dividends and liquidation, conversion and redemption rights, and sinking fund provisions. We continue to seek capital for our business, and this additional capital may be raised through the issuance of additional preferred stock.

If A Large Number Of Our Shares Are Sold All At Once Or In Blocks, The Market Price Of Our Shares Would Most Likely Decline.

Our shareholders are not restricted in the price at which they can sell their shares. Shares sold at a price below the current market price at which our Common Stock is trading may cause the market price of our Common Stock to decline.

A Significant Portion Of Our Investments Are Currently Illiquid, Which May Impact Our Operating Results.

Our long-term investment in marketable securities balance consists of auction rate securities with a par value of approximately $5.2 million as of the date of this filing, which at present are highly illiquid. In the event we need immediate access to these funds, we will not be able to sell these investments at par value. These instruments are expected to remain illiquid until a future auction of these investments is successful, buyers are found outside of the auction process, they are redeemed by the issuing agencies, or we prevail in our litigation against Deutsche Bank which may result in Deutsche Bank providing us liquidity alternatives. We have partially offset the consequences of this illiquidity by securing a line of credit collateralized by the auction rates securities; however the amount we can borrow against our collateral is limited by the Financial Industry Regulatory Authority (“FINRA”). In the event these securities are deemed to be permanently impaired, we will be required to take a charge to operations in recognition of this impairment.

The Market For Our Stock Is Subject To Rules Relating To Low-Priced Stock (“Penny Stock”) Which May Limit Our Ability To Raise Capital.

Our Common Stock is currently listed for trading in the FINRA OTC Bulletin Board Market and is subject to the “penny stock rules” adopted pursuant to Section 15(g) of the Exchange Act. In general, the penny stock rules apply to non-NASDAQ or non-national stock exchange companies whose common stock trades at less than $5.00 per share or which have tangible net worth of less than $5,000,000 ($2,000,000 if the company has been operating for three or more years). Such rules require, among other things, that brokers who trade “penny stock” on behalf of persons other than “established customers” complete certain documentation, make suitability inquiries of investors and provide investors with certain information concerning trading in the security, including a risk disclosure document, quote information, broker’s commission information and rights and remedies available to investors in penny stocks. Many brokers have decided not to trade “penny stock” because of the requirements of the penny stock rules, and as a result, the number of broker-dealers willing to act as market makers in such securities is limited. The “penny stock rules,” therefore, may have an adverse impact on the market for our Common Stock and may affect our ability to raise additional capital if we decide to do so.

Our Share Price Could Decline As A Result Of Short Sales.

When an investor sells stock that he does not own, it is known as a short sale. The seller, anticipating that the price of the stock will go down, intends to buy stock to cover his sale at a later date. If the price of the stock goes down, the seller will profit to the extent of the difference between the price at which he originally sold it less his later purchase price. Short sales enable the seller to profit in a down market. Short sales could place significant downward pressure on the price of our Common Stock. Penny stocks which do not trade on an exchange, such as our Common Stock, are particularly susceptible to short sales.

Our Future Success Depends In Significant Part Upon The Continued Services Of Our Key Senior Management.

Our future success depends in significant part upon the continued services of our key senior management personnel. The competition for highly qualified personnel is intense, and we may not be able to retain our key managerial employees or attract and retain additional highly qualified technical and managerial personnel in the future. None of our employees are represented by a labor union, and we consider our relations with our employees to be good. None of our employees are covered by key man life insurance policies

ITEM 3.

LEGAL PROCEEDINGS

Litigation

Patent Litigation

On February 8, 2008, we, TPL and Alliacense Ltd. were named as defendants in three separate lawsuits filed in the United States District Court for the Northern District of California by Asustek Computer, Inc., HTC Corporation, and Acer, Inc., and affiliated entities of each of them.

The Asustek case sought declaratory relief that its products do not infringe enforceable claims of the '336 and '584 patents and US 5,440,749 (the “749 patent”). The Asustek case also sought a similar declaration with respect to two patents owned by TPL that are not a part of the MMP Portfolio, and as such we are not engaged in this aspect of the litigation and defense. On December 22, 2008, we announced that Asustek had purchased a MMP Portfolio license and that case has settled.

The Acer case seeks declaratory relief that its products do not infringe enforceable claims of the '336, '584, ‘749, '148 patents and US 5,530,890 (the “890 patent”). The HTC case similarly seeks declaratory relief that its products do not infringe enforceable claims of those patents. We allege counterclaims for patent infringement of the '336, '749, '148 and '890 patents against Acer and HTC. On June 16, 2009, District Court Judge Jeremy Fogel stayed the HTC and Acer actions until September 18, 2009. The stay has now been lifted and the cases are in the discovery and pre-claims construction phase.

On December 1, 2008, we, TPL and Alliacense, Ltd. were named as defendants in a lawsuit filed in the United States District Court for the Northern District of California by Barco, N.V. The Barco case seeks declaratory relief that its products do not infringe enforceable claims of the '584, '749 and '890 patents. We allege counterclaims for patent infringement of our '749, '890 and '336 patents. On June 22, 2009, Judge Fogel also stayed the Barco case until September 18, 2009. That stay has now been lifted and the case is deemed related to the Acer and HTC cases. The case is now in the discovery and pre-claims construction phase.

On April 29, 2009, we, TPL, and Alliacense Ltd., were named as defendants in a lawsuit filed in the United States District Court for the Southern District of New York by Sirius XM Radio, Inc. The Sirius case seeks declaratory relief that its products do not infringe enforceable claims of our '749, '584, '890, '336 and '148 patents, and additionally two patents of TPL's "fast logic" portfolio which do not involve us. The Sirius case was deemed related to the Acer, HTC and Barco cases. A settlement of the Sirius action has been finalized and that action was dismissed on July 30, 2010.

In the HTC and Barco cases the parties have stipulated to non-infringement of the ‘584 patent and that patent will not be litigated in those cases.

Deutsche Bank Arbitration

On October 16, 2008, we initiated binding arbitration claims before FINRA against Deutsche Bank Securities, Inc., and affiliates ("DBSI") based on advisory services provided to us resulting in our purchases of auction rate securities ("ARS") and the failure of the ARS market in February 2008. We experienced a loss of liquidity and other damages as a result and allege DBSI engaged in negligence and nondisclosure in providing us services. DBSI has answered our claims, and an arbitration panel has been selected. Document discovery has been initiated. Some instruments have been repurchased by the issuers since the claim was filed (see Note 6). The arbitration is scheduled to begin August 30, 2010.

DBSI's parent, Deutsche Bank AG, denied being required to arbitrate the dispute with DBSI before FINRA, and so we filed an action against Deutsche Bank AG in the United States District Court for the Southern District of California based on its liability with respect to our investments in ARS. A stay of this action will likely be in place through the FINRA arbitration with DBSI.

Crossflo Systems, Inc. Litigation

Under the terms of our Agreement and Plan of Merger (the "Merger Agreement") with Crossflo, and certain of its principal officers, an escrow account was established to hold back approximately 10% of the merger consideration payable to the shareholders of Crossflo (the "Escrow Merger Consideration"). We contend that certain representations and warranties made by Crossflo and certain of its principal officers in the Merger Agreement were false when made, and were false as of the closing of the merger. We submitted a demand to the escrow agent on August 31, 2009 not to release the Escrow Merger Consideration to the Crossflo shareholders and to instead return it to us. A sufficient number of Crossflo shareholders have opposed our demand that the escrow consideration has not been released to either side.

On August 31, 2009, we initiated an arbitration proceeding before the American Arbitration Association against the three Crossflo principal officers who were signatories to the Merger Agreement alleging they provided false representations and warranties in the Merger Agreement and alleging nondisclosure of information about Crossflo during the due diligence process leading up to the merger. Those three principal officers deny our claims and have filed counterclaims. Briefing to determine the scope of counterclaims to be arbitrated is pending before the arbitrator. The arbitration is scheduled to begin February 13, 2011.

TPL Litigation

On April 12, 2010, we filed an action against Technology Properties Limited LLC ("TPL") in San Diego Superior Court for breach of a promissory note of $1 million issued to us by TPL on January 12, 2010 and which became due and payable on February 28, 2010. TPL has filed an answer and various defenses denying the claim.

On April 22, 2010 we filed a second action against TPL and Alliacense LLC in Santa Clara Superior Court alleging claims for breach of contract, breach of fiduciary duty, aiding and abetting breach of fiduciary duty, and interference with contract, constructive fraud, for preliminary and permanent injunctions and for an accounting. The Action stemmed from TPL's notification of a license written in April 2010 which included a license of the MMP patents and other patent to use portfolios and technologies co-owned and potentially owned by TPL in the future. We objected to the amount of license consideration allocated to the MMP patent license as too low relative to the other license components.

On April 26, 2010, the Court granted our application for a Temporary Restraining Order ("TRO") precluding TPL from executing any license of the MMP patents without providing us five business days' notice of the proposed MMP license and any other proposed license with the licensor, in order to allow us time to seek redress if we are dissatisfied by the proposed licenses. At that time, TPL filed motions to seal the file and to bar press releases commenting on the contents of the court file, and a motion to compel private arbitration of the dispute.

The Court granted the motion to seal provisionally until TPL's motions were fully briefed and argued and set a hearing on our request that the TRO become a Preliminary Injunction through trial.

Following this, the parties entered into negotiations to restructure their relationship by providing generally for PDS and PTSC oversight of Alliacense operations and to finance Alliacense's operations in pursuit of MMP licensing. Those negotiations proceeded for nearly three months. While the negotiations were underway, the parties stipulated to postpone the briefing on the motions several times. Those negotiations failed and are not continuing. However TPL stipulated on August 3, 2010 that the TRO already in place would become a Preliminary Injunction. On August 12, 2010, the Court considered defendants' request to seal the file indefinitely and to compel private arbitration of the dispute and denied both Motions. On August 13, 2010 the Court provisionally allowed some file redactions pursuant to a Motion filed by TPL and will decide the appropriateness of those redactions on September 30, 2010.

ITEM 5.

MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

Our Common Stock is currently listed for trading in the FINRA Over-The-Counter Bulletin (“OTC”) Board Market under the symbol PTSC. Prices reported represent prices between dealers, do not include markups, markdowns or commissions and do not necessarily represent actual transactions. The market for our shares has been sporadic and at times very limited.

The following table sets forth the high and low closing bid quotations for our Common Stock for the fiscal years ended May 31, 2010 and 2009.

	BID QUOTATIONS
	HIGH		LOW
Fiscal Year Ended May 31, 2010
First Quarter	$	0.18	$	0.11
Second Quarter	$	0.36	$	0.14
Third Quarter	$	0.19	$	0.12
Fourth Quarter	$	0.15	$	0.09

	HIGH		LOW
Fiscal Year Ended May 31, 2009
First Quarter	$	0.30	$	0.17
Second Quarter	$	0.24	$	0.10
Third Quarter	$	0.17	$	0.10
Fourth Quarter	$	0.15	$	0.08

On July 31, 2010 the closing price of our stock was $0.20 and we had approximately 695 shareholders of record. Because most of our Common Stock is held by brokers and other institutions on behalf of stockholders, we are unable to estimate the total number of beneficial owners represented by these record holders.

Dividend Policy

On February 22, 2007, our Board of Directors adopted a semi-annual dividend payment policy, subject to determination by our Board of Directors in light of our financial condition, other possible applications of our available resources, and relevant business considerations. We paid no dividends during the fiscal years ended May 31, 2010 and 2009.

Equity Compensation Plan Information

Our stockholders previously approved each of our 2001, 2003 and 2006 Stock Option Plans. The following table sets forth certain information concerning aggregate stock options authorized for issuance under our 2001, 2003 and 2006 Stock Option Plans as of May 31, 2010. For a narrative description of the material features of the plans, refer to footnote 17 of our consolidated financial statements.

Shares of Common Stock issuable on the exercise of warrants have not been approved by our stockholders. This item has been segregated in the table below under the item “Equity award plan not approved by security holders”.

Plan Category	Number of securities to be issued upon exercise of outstanding options and warrants		Weighted-average exercise price of outstanding options and warrants		Number of securities remaining available for future issuance under equity compensation plans
Equity compensation plans approved by security holders		5,637,917	$	0.42		8,709,487
Equity award plan not approved by security holders		325,000	$	0.53		—
Total		5,962,917				8,709,487

The securities in the equity award plan not approved by stockholders above, consist of warrants to purchase 300,000 shares of common stock at exercise prices of $0.20 to $1.00 per share issued to our past investor relations firm in exchange for services as specified in their engagement contract and a warrant to purchase 25,000 shares of our common stock at an exercise price of $0.15 per share issued in connection with a legal settlement.

The number of securities available for future issuance under our stock option plans is as follows at May 31, 2010: 2001 Stock Option Plan 599,000 shares, 2003 Stock Option Plan 2,623,404 shares, 2006 Stock Option Plan 5,487,083 shares.

Company Stock Price Performance

The stock price performance graph below will not be deemed to be incorporated by reference into any of our filings by any general statement incorporating information into any of our filings under the Securities Act of 1933, as amended (the “Securities Act”), or under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), except to the extent that we specifically incorporate this information by reference, and shall not otherwise be deemed soliciting material or filed under the Securities Act or the Exchange Act.

The following graph compares the five-year cumulative total return on our common stock to the total returns of 1) NASDAQ Composite Index and 2) Philadelphia Semiconductor Index. This comparison assumes in each case that $100 was invested on May 31, 2005 and all dividends were reinvested. Our fiscal year ends on May 31.

Recent Sale of Unregistered Securities

None.

Issuer Purchases of Equity Securities

On April 28, 2006 our Board of Directors authorized a stock repurchase program. We commenced the program in July 2006 and plan to repurchase outstanding shares of our Common Stock on the open market from time to time. We repurchased Common Stock during the fourth quarter of fiscal year 2010 using available cash resources as follows:

Period	Total Number of Shares Purchased	Average Price Paid per Share		Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs
March 1 - 31, 2010	108,996	$	0.15	108,996
April 1 - 30, 2010	285,116	$	0.12	285,116
May 1 - 31, 2010	181,493	$	0.10	181,493
Total	575,605	$	0.12	575,605

The repurchase plan has no maximum number of shares and is solely at the discretion of the Board of Directors. The repurchase plan has no set expiration date.

ITEM 7.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

THIS ANNUAL REPORT ON FORM 10-K CONTAINS FORWARD-LOOKING STATEMENTS CONCERNING FUTURE EVENTS AND PERFORMANCE OF OUR COMPANY. YOU SHOULD NOT RELY ON THESE FORWARD-LOOKING STATEMENTS, BECAUSE THEY ARE ONLY PREDICTIONS BASED ON OUR CURRENT EXPECTATIONS AND ASSUMPTIONS. MANY FACTORS COULD CAUSE OUR ACTUAL RESULTS TO DIFFER MATERIALLY FROM THOSE INDICATED IN THESE FORWARD-LOOKING STATEMENTS. YOU SHOULD REVIEW CAREFULLY THE RISK FACTORS IDENTIFIED IN THIS REPORT AS SET FORTH BELOW AND UNDER THE CAPTION “RISK FACTORS.” WE DISCLAIM ANY INTENT TO UPDATE ANY FORWARD-LOOKING STATEMENTS TO REFLECT SUBSEQUENT ACTUAL EVENTS OR DEVELOPMENTS.

Overview

In June 2005, we entered into a series of agreements with TPL and others to facilitate the pursuit of unlicensed users of our intellectual property. We intend to continue our joint venture with TPL to pursue license agreements with unlicensed users of our technology. We believe that utilizing the option of working through TPL, as compared to creating and using our own licensing team for those activities, avoids a competitive devaluation of our principal assets and is a prudent way to achieve the desired results as we seek to obtain fair value from users of our intellectual property. In April 2010, we filed an action against TPL regarding TPL’s management of the MMP portfolio.

During fiscal 2010 and through the date of this filing we and TPL each contributed $580,000 to fund the working capital of PDS. We expect the contributions to continue in the future due to the working capital demands of PDS. Additionally, we have loaned TPL $1,950,000 intended to cover its operating costs including the furtherance of licensing our MMP Portfolio of microprocessor patents. At February 28, 2010, we have reserved $1,013,151 against the $1,000,000 note receivable which includes accrued interest. In April 2010, we filed suit against TPL for breach of contract regarding the $1,000,000 note non-payment. On July 15, 2010, we received $1,003,095 consisting of principal and interest through July 15, 2010 on the $950,000 secured note.

On October 5, 2009, we announced a reorganization of PDSG and our management. On November 12, 2009, we announced our intent to divest the Iameter portfolio of data analysis and software programs; and on January 25, 2010, we sold the Iameter assets. During August 2010, we sold the Vigilys business line. As a result of our reorganization and PDSG’s continued inability to meet its business plan, we have incurred impairment charges for our intangibles and goodwill in the PDSG segment of our business. We continue to fund the day to day operating costs of PDSG while continuing to reduce expenses. Our merger and acquisition activities have ceased since our October 2009 reorganization.

Cash shortfalls and liquidity issues currently experienced by PDS and TPL, and continued negative cash flows incurred by PDSG, will have an adverse effect on our liquidity. Accordingly, we are in the process of examining alternatives that could allow for the partnering or divestiture of PDSG. If successful, these measures may provide for a further reduction in expenses and cash use, or additionally in the event of divestiture, cash proceeds.

We are currently in litigation with TPL arising from the April 2010 actions filed for breach of the Commercialization Agreement and TPL’s default on the $1,000,000 unsecured note. See Part 1, Item 3. “Legal Proceedings” as well as Part 1, Item 1A. “Risk Factors” in this Annual Report for more information.

Critical Accounting Policies and Estimates

Our consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America, which require us to make estimates and judgments that significantly affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. Actual results could differ from those estimates, and such differences could affect the results of operations reported in future periods. We believe the following critical accounting policies affect our most significant estimates and judgments used in the preparation of our consolidated financial statements.

1.	Revenue Recognition

Historically we recognized revenue from the sale of our microprocessor chips upon shipment to the customer, at which time title transferred and we had no further obligations. We discontinued the sale of our microprocessor chips during the first fiscal quarter of 2009. Revenue from technology license agreements is recognized at the time a contract is entered into, the license method is determined (paid-in-advance or on-going royalty), and the customer is provided with the licensed technology, if applicable. Fees for maintenance or support are recorded on a straight-line basis over the underlying period of performance.

Our wholly-owned subsidiary PDSG sells software and services to end users primarily through relationships with systems integrators and prime contractors. PDSG’s revenue is derived primarily from the following sources: (i) software licensing, (ii) related professional services, and (iii) post contract customer support (“PCS”) agreements. PCS agreements typically include software updates, on a when and if available basis, and telephone and Internet access to technical support personnel. Software updates provide customers with rights to unspecified software product upgrades and to maintenance releases and patches released during the term of the support period. Revenue for support services is recognized on a straight-line basis over the support period.

When a sale involves multiple elements, PDSG allocates the entire fee from the arrangement to each respective element based on its Vendor Specific Objective Evidence (“VSOE”) of fair value and recognizes revenue when each element’s revenue recognition criteria are met. VSOE of fair value for each element is established based on the price charged when the same element is sold separately. PDSG has not yet demonstrated VSOE for the professional services that are rendered in conjunction with its software license sales. Accordingly, we have combined their presentation on our consolidated statements of operations under the caption “License and service revenue.”

The majority of PDSG’s contracts with customers, including systems integrators and prime contractors, are multiple element arrangements which contain professional services that are considered essential to the functionality of the other elements of the arrangement. PDSG accounts for revenue on these arrangements according to authoritative guidance for contract accounting. PDSG recognizes revenue based on progress towards contract completion measured by actual hours incurred in relation to the estimate of total expected hours. PDSG measures revenues by applying the contract-specific estimated percentage of completion to the total contract amount for software and professional services. PDSG routinely updates the estimates of future hours for agreements in process and reports any cumulative effects of such adjustments in current operations. PDSG immediately recognizes any loss expected on these contracts when it is projected that a loss is probable.

In certain situations where PDSG’s customer contracts contain acceptance criteria or other conditions that are deemed adverse to the probability of collection, revenues recognized are limited to the amount of cash already collected.

Prior to its deconsolidation on May 1, 2009, our variable interest entity, Holocom, Inc. (“Holocom”) recognized revenue upon shipment of its product or upon receipt of its product by the customer when shipped FOB destination and recognized revenue on its short-term installation contracts as time and materials costs were incurred.

2.	Assessment of Contingent Liabilities

We are involved in various legal matters, disputes, and patent infringement claims which arise in the ordinary course of our business. We accrue for any estimated losses at the time when we can make a reliable estimate of such loss and it is probable that it has been incurred. By their very nature, contingencies are difficult to estimate. We continually evaluate information related to all contingencies to determine that the basis on which we have recorded our estimated exposure is appropriate.

3.	Stock Options and Warrants

We follow authoritative guidance which establishes standards for the accounting of transactions in which an entity exchanges its equity instruments for goods or services, primarily focusing on accounting for transactions where an entity obtains employee services in share-based payment transactions. We are required to measure the cost of employee services received in exchange for an award of equity instruments, including stock options, based on the grant-date fair value of the award and to recognize it as compensation expense over the period the employee is required to provide service in exchange for the award, usually the vesting period.

Stock-based compensation expense recognized during the period is based on the grant date fair value of the portion of share-based payment awards ultimately expected to vest during the period. As stock-based compensation expense recognized in the consolidated statements of operations is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Forfeiture rates are based on historical forfeiture experience and estimated future employee forfeitures.

4.	Income Taxes

We must assess the likelihood that we will be able to recover our deferred tax assets. If recovery is not likely, we must increase our provision for taxes by recording a valuation allowance against the deferred tax assets that we estimate will not ultimately be recoverable. We believe that a substantial majority of the deferred tax assets recorded on our balance sheet will ultimately be recovered. However, should there be a change in our ability to recover the deferred tax assets; the tax provision would increase in the period in which we determined that the recovery was not probable.

We follow authoritative guidance to reduce the diversity in practice associated with certain aspects of measurement and recognition in accounting for income taxes. This authoritative guidance prescribes a recognition threshold and measurement requirement for the financial statement recognition of a tax position that has been taken or is expected to be taken on a tax return and also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. Under this guidance we may only recognize tax positions that meet a “more likely than not” threshold.

We follow authoritative guidance to adjust our effective tax rate each quarter to be consistent with the estimated annual effective tax rate. We are also required to record the tax impact of certain discrete items, unusual or infrequently occurring, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, in the interim period in which they occur. In addition, jurisdictions with a projected loss for the year or a year-to-date loss where no tax benefit can be recognized are excluded from the estimated annual effective tax rate. The impact of such an exclusion could result in a higher or lower effective tax rate during a particular quarter, based upon the mix and timing of actual earnings versus annual projections.

5.	Investments in Affiliated Companies

We have a 50% interest in PDS. We account for our investment using the equity method of accounting since the investment provides us the ability to exercise significant influence, but not control, over the investee. Significant influence is generally deemed to exist if we have an ownership interest in the voting stock of the investee of between 20% and 50%, although other factors, such as representation on the investee’s Board of Directors, are considered in determining whether the equity method of accounting is appropriate. Under the equity method of accounting, the investment, originally recorded at cost, is adjusted to recognize our share of net earnings or losses of the investee and is presented in the consolidated statements of operations in the caption “Equity in earnings of affiliated companies, net.”

We had a 39.4% interest in Talis. Prior to the write off of our investment in Talis during the quarter ended August 31, 2009, we were accounting for our investment using the equity method of accounting. Under the equity method of accounting, the investment, originally recorded at cost, was adjusted to recognize our share of net earnings or losses of the investee and was presented in the consolidated statements of operations in the caption “Equity in earnings of affiliated companies, net.”

We owned 37.1% of the preferred stock of Avot. This investment was accounted for at cost since we did not have the ability to exercise significant influence over the operating and financial policies of Avot.

We own 100% of the preferred stock of Holocom. This investment has historically been accounted for at cost since we do not have the ability to exercise significant influence over the operating and financial policies of Holocom. Due to a re-consideration event on May 1, 2009, this investment was carried at cost plus the effects of deconsolidation of this variable interest entity on our consolidated balance sheet.

We review our investments in these affiliated companies to determine whether events or changes in circumstances indicate that the carrying amounts may not be recoverable. The primary factors we consider in our determination are the financial condition, operating performance and near term prospects of the investees. If the decline in value is deemed to be other than temporary, we would recognize an impairment loss.

6.	Business Combinations and Intangible Assets Including Goodwill

We account for business combinations using the purchase method of accounting and accordingly, the assets and liabilities of the acquired entities are recorded at their estimated fair values at the acquisition date. Goodwill represents the excess of the purchase price over the fair value of net assets, including the amount assigned to identifiable intangible assets. Due to the time it takes to obtain pertinent information to finalize the acquired company’s balance sheet, it may be several quarters before we are able to finalize the initial fair value estimates. Accordingly, it is not uncommon for the initial estimates to be subsequently revised. The results of operations of acquired businesses are included in our consolidated financial statements from the acquisition date.

Identifiable intangible assets with finite lives are amortized over their estimated useful lives on a straight line basis. Goodwill and intangible assets are tested for impairment on an annual basis, or sooner if an indicator of impairment occurs.

Holocom

During the eleven months ended April 30, 2009, we recorded sales amounting to approximately $4,709,000 by our then consolidated variable interest entity, Holocom, with cost of sales amounting to approximately $2,136,000. Due to a re-consideration event we deconsolidated Holocom in May 2009 and no longer include Holocom’s revenues in our results of operations.

PDSG

We acquired PDSG in a series of transactions in the second, third and fourth quarters of fiscal 2009. Revenue consists of software licenses and associated services relating to PDSG’s CDX data agent product and the Sherlock™ software tool for medical facilities. In January 2010 we sold the Iameter portfolio which included the Sherlock™ software tool for medical facilities. Cost of sales includes the direct time of PDSG employees on each project as well as outside contractors.

Revenues decreased during fiscal year ended May 31, 2010, as compared to the fiscal year ended May 31, 2009, due primarily to the inclusion in the fiscal year 2009 period of amounts from a significant customer agreement not duplicated in the fiscal year 2010. Also in 2010, revenue progress on contracts was slowed primarily as a result of customer initiated delays resulting in lower than planned revenues. In general, revenue agreements are one time contracts that vary in size and scope depending upon the requirements of the customer.

The impairment charge for the fiscal year ended May 31, 2010, represents the write off of PDSG’s purchased intangibles to a fair value of $1,860,000 at November 30, 2009. These assets were subject to revaluation pursuant to a reconsideration event which also drove the restructuring of PDSG initiated in October 2009. The impairment is primarily attributable to management’s current assessment of reduced revenue and resultant cash flow projections as compared to what previously had been the expectations for the business.

PTSC

During the fiscal year ended May 31, 2009, we recognized maintenance fee revenues totaling approximately $19,000 in connection with an agreement with AMD Corporation during the 2005 fiscal year. The agreement called for maintenance fees totaling $100,000 connected with a license agreement for our Ignite technology; the license fee revenue was being recognized as revenue evenly over the four year period of the license, the four year period ended in February 2009.

In addition during the fiscal year ended May 31, 2009, we recorded sales of approximately $33,000, from the sale of microprocessor chips that we no longer market. Inventory associated with the sales of these microprocessor chips is carried at zero value. Our final sales of microprocessor chips occurred during the quarter ended August 31, 2008.

Consolidated

Our revenues decreased from approximately $5,355,000 for the fiscal year ended May 31, 2009 to approximately $568,000 for the fiscal year ended May 31, 2010, primarily due to the exclusion of Holocom from our consolidated financial statements for fiscal 2010. Our revenue amounts do not include income of approximately $10,193,000 and $4,483,000, respectively, from our investment in PDS and losses of approximately $488,000 and $21,700, respectively, from our investment in Talis for the fiscal year ended May 31, 2009 and 2010, respectively.

		May 31, 2010				May 31, 2009
Research and development		$	1,503,724			$	510,848

PDSG

Research and development costs consist of PDSG’s payroll and related expenses for software engineers as well as outside contractors retained to assist in the development of PDSG’s software products. For the fiscal years ended May 31, 2010 and 2009, approximately $19,500 and $1,500, respectively, of non-cash compensation was recorded in connection with vesting of employee stock options. We acquired PDSG in a series of transactions in the second, third and fourth quarters of fiscal 2009, as such, fiscal 2009 does not contain twelve months of expenses as compared to fiscal 2010. Additionally, in fiscal 2010 PDSG incurred an increase in outside contractor costs of approximately $211,000 related to the completion of CDX4.

Holocom

During the eleven months ended April 30, 2009, we recorded selling, general and administrative expenses amounting to approximately $2,082,000 by our then consolidated variable interest entity, Holocom including approximately $6,000 of non-cash compensation recorded in connection with vesting of employee stock options. Due to a re-consideration event we deconsolidated Holocom in May 2009.

PDSG

We acquired PDSG in a series of transactions in the second, third and fourth quarters of fiscal 2009. Selling, general and administrative expenses of approximately $2,542,000 for the fiscal year ended May 31, 2009, represent costs from September 1, 2008, to May 31, 2009, as compared to approximately $2,715,000 for the fiscal year ended May 31, 2010. Increases are primarily due to nine months of expenses reported in fiscal 2009 as compared to twelve months of expenses in fiscal 2010. In fiscal year 2010, payroll and related costs increased by approximately $41,500 primarily resulting from one-time severance payments offset by a decrease in payroll and related costs due to restructuring. Other fiscal 2010 increases were approximately $93,000 in rent and utilities expenses due to the space required for the Iameter and Vigilys acquisitions after November 30, 2008 and approximately $54,000 in consulting expenses for sales lead generations. For the fiscal years ended May 31, 2010 and 2009, approximately $49,500 and $47,000, respectively, of share-based compensation was recorded in connection with vesting of employee stock options.

PTSC

Selling, general and administrative expenses decreased from approximately $3,940,000 for the fiscal year ended May 31, 2009 to approximately $3,816,000 for the fiscal year May 31, 2010. The decrease consisted primarily of approximately $200,000 in accounting and auditing expenses due to one-time fiscal 2009 expenses related to the PDSG acquisition and the elimination of audit services for Holocom in fiscal 2010, approximately $156,000 in public and investor relations expenses due to fiscal 2010 cost-cutting measures, approximately $102,000 in salaries and related expenses due to fiscal 2010 restructuring and approximately $59,000 in travel and related expenses. These decreases were offset by increases in legal expenses of approximately $342,000 due to fiscal 2010 litigation with the former officers of Crossflo, litigation with Deutsche Bank and litigation with TPL, and increases in consulting expenses of approximately $338,000 related to planning and partnering strategies for PDSG. For the fiscal years ended May 31, 2009 and 2010, approximately $364,000 and $153,000, respectively, of share-based compensation was recorded in connection with vesting of employee stock options.

Consolidated

Selling, general and administrative expenses decreased from approximately $8,564,000 for the fiscal year ended May 31, 2009 to approximately $6,531,000 for the fiscal year ended May 31, 2010, primarily due to the exclusion of Holocom from our fiscal 2010 results.

Our other income and expenses for the fiscal year ended May 31, 2010 included equity in the earnings of PDS consisting of net income after expenses in the amount of approximately $4,483,000 and our share of loss in Talis consisting of approximately $21,700 after expenses. For the fiscal year ended May 31, 2009, our other income and expenses included equity in the earnings of PDS consisting of net income after expenses in the amount of approximately $10,193,000 and our share of loss in Talis consisting of approximately $488,000 after expenses. Our investment in PDS is, and our investment in Talis was, accounted for in accordance with the equity method of accounting for investments.

During fiscal 2010 due to the inability of our investments to meet their business plans, to raise capital and to the general economic environment, we recorded an impairment of our investments in: Holocom of approximately $435,000, Talis of approximately $680,000, and Avot of approximately $433,000. At May 31, 2009, it was determined that our investment in Avot was impaired by approximately $867,000.

During fiscal 2010, we recorded a reserve for loan loss of approximately $1,013,000 on our note receivable with TPL, LLC which was due February 28, 2010.

During fiscal 2010, we recorded a gain on our sale of the Iameter portfolio of assets of approximately $182,000.

Total other income and expense for the fiscal year ended May 31, 2010 amounted to net other income of approximately $1,964,000 compared with net other income of approximately $9,116,000 for the fiscal year ended May 31, 2009. Interest income and other income decreased from approximately $337,000 for the fiscal year ended May 31, 2009 to approximately $145,000 for the fiscal year ended May 31, 2010 due to declines in interest rates for our cash, cash equivalents and marketable securities accounts.

During the fiscal year ended May 31, 2010, we recorded a benefit for income taxes of approximately $3,928,000 and during the fiscal year ended May 31, 2009, we recorded a provision for income taxes of approximately $964,000 related to federal and California taxes. At May 31, 2010 we have federal and state net operating loss (“NOL”) carryforwards available to offset future taxable income of approximately $14,281,000 and $14,966,000, respectively primarily arising from our acquisition of PDSG. These NOL carryforwards expire in the years ending May 31, 2023 and 2013, respectively. The State of California has suspended NOL deductions for taxable years beginning in 2008 or 2009 for taxpayers with business income of $500,000 or more.

We recorded a net loss for the fiscal year ended May 31, 2010 of $6,679,821 compared with net income of $881,509 for the fiscal year ended May 31, 2009. The reason for our decline in net income as compared with the prior year is due to the decline in our share of income from PDS, our write offs of intangibles, goodwill and investments in affiliated companies and our reserve for loan loss.

Holocom

During the eleven months ended April 30, 2009 and twelve months ended May 31, 2008, we recorded sales amounting to approximately $4,709,000 and $3,650,000, respectively, by our consolidated variable interest entity, Holocom, with cost of sales amounting to approximately $2,136,000 and $1,510,000, respectively. The increase in sales for Holocom during the eleven months ended April 30, 2009 as compared to the twelve months ended May 31, 2008 is primarily due to the expansion of Holocom’s distributor network and addition of product sales to new customers.

PDSG

We acquired Crossflo on September 1, 2008, the assets of Verras Medical, Inc. (“Verras”) on December 1, 2008 and the Vigilys business line on March 27, 2009 all of which were combined into PDSG. Revenue consists of software licenses and related services relating to PDSG’s CDX data agent product and services provided by PDSG to medical facilities utilizing the Sherlock™ software tool. Cost of sales includes the direct time of PDSG employees on each project as well as outside contractors. Included in cost of sales is approximately $662,000 of amortization expense on purchased intangible assets.

PTSC

During the fiscal year ended May 31, 2009 and 2008, we recognized maintenance fee revenues totaling approximately $18,700 and $25,000 in connection with an agreement with AMD Corporation during the 2005 fiscal year. The agreement called for maintenance fees totaling $100,000 connected with a license agreement for our Ignite technology; the license fee revenue was recognized as revenue evenly over the four year period of the license, the four year period ended in February 2009.

In addition during the fiscal year ended May 31, 2009 and 2008, we recorded sales of approximately $33,000 and $33,000, respectively, from the sale of microprocessor chips that we no longer market. Inventory associated with the sales of these microprocessor chips is carried at zero value. Our final sales of microprocessor chips occurred during the quarter ended August 31, 2008.

Consolidated

Our revenues increased from approximately $3,708,000 for the fiscal year ended May 31, 2008 to approximately $5,355,000 for the fiscal year ended May 31, 2009. Our revenue amounts do not include income of approximately $19,926,000 and $10,193,000, respectively, from our investment in PDS and losses of approximately $8,400 and $488,000, respectively, from our investment in Talis for the fiscal year ended May 31, 2008 and 2009, respectively.

Selling, general and administrative expenses increased from approximately $1,997,000 for the twelve months ended May 31, 2008 to approximately $2,082,000 for the eleven months ended April 30, 2009. The increase consisted of approximately $38,000 relating to payroll, bonuses and related expenses, approximately $29,000 for meals and internal events, approximately $37,000 for royalty payments under the Earn Out Agreement, and approximately $62,000 for legal and professional expenses. For the eleven months ended April 30, 2009, approximately $6,000 of non-cash compensation was recorded in connection with vesting of employee stock options. These increases were offset by a decrease in travel and related expenses of approximately $73,000.

Selling, general and administrative expenses decreased from approximately $4,972,000 for the fiscal year ended May 31, 2008 to approximately $3,940,000 for the fiscal year May 31, 2009. The decrease consisted of approximately $811,000 in legal and accounting expense, primarily due to a settlement with a former officer of cash and stock in the prior fiscal year, a decrease in general legal matters, approximately $111,000 in public and investor relations expenses, approximately $28,000 in consulting expenses and approximately $45,000 in D&O insurance expenses. These decreases were offset by increases in payroll and related expenses of approximately $177,000 related to officer bonuses, and approximately $14,000 in travel and related expenses. For the fiscal year ended May 31, 2009, approximately $364,000 of non-cash compensation was recorded in connection with vesting of employee stock options as compared to approximately $503,000 for the fiscal year ended May 31, 2008.

Our other income and expenses for the fiscal year ended May 31, 2009 included equity in the earnings of PDS consisting of net income after expenses in the amount of approximately $10,193,000 and our share of loss in Talis consisting of approximately $488,000 after expenses. For the fiscal year ended May 31, 2008, our other income and expenses included our share of income in PDS of approximately $19,926,000 and our share of loss in Talis consisting of approximately $8,400. Our investments in PDS and Talis are accounted for in accordance with the equity method of accounting for investments.

Total other income and expense for the fiscal year ended May 31, 2009 amounted to net other income of approximately $9,118,000 compared with approximately $21,537,000 for the fiscal year ended May 31, 2008. Interest income and other income decreased from approximately $1,470,000 for the fiscal year ended May 31, 2008 to approximately $347,000 for the fiscal year ended May 31, 2009 due to declines in interest rates for our cash, cash equivalents and short term investment accounts. Holocom recognized $150,000 of other income in connection with the sale of a portion of its interest in Talis.

During the fiscal year ended May 31, 2009 and 2008, we recorded a provision for income taxes of approximately $964,000 and $6,426,000, respectively, related to federal and California taxes. At May 31, 2009 we have federal and state net operating loss (“NOL”) carryforwards available to offset future taxable income of approximately $11,975,000 and $11,894,000, respectively primarily arising from our acquisition of PDSG. These NOL carryforwards expire in the years ending May 31, 2023 and 2013, respectively. The State of California has suspended NOL deductions for taxable years beginning in 2008 or 2009 for taxpayers with business income of $500,000 or more.

We recorded net income for the fiscal year ended May 31, 2009 of $881,509 compared with net income of $9,388,321 for the fiscal year ended May 31, 2008. The reason for our decline in net income as compared with the prior year is due to the decline in our share of income from PDS and our acquisition of PDSG.

LIQUIDITY AND CAPITAL RESOURCES

Liquidity

Our cash and short-term marketable securities balances increased from approximately $6,265,000 as of May 31, 2009 to approximately $10,352,000 as of May 31, 2010. We also have restricted cash balances amounting to approximately $52,000 as of May 31, 2009 and approximately $21,000 as of May 31, 2010. Total current assets increased from approximately $8,065,000 as of May 31, 2009 to approximately $13,417,000 as of May 31, 2010. Total current liabilities amounted to approximately $1,034,000 and approximately $942,000 as of May 31, 2009 and May 31, 2010, respectively. The change in our current position as of May 31, 2010 as compared with May 31, 2009 results primarily from the redemption of $6.1 million in par value of our ARS securities during the fiscal year 2010 and our note receivable issuances during the fiscal ended May 31, 2010.

During June 2008, we obtained a credit facility for as long as needed, which provides for financing based on the par value balance of our outstanding auction rate securities. The facility is collateralized by the full value of the outstanding auction rate securities, required no origination fee, and bears interest at the federal funds rate plus 3%. On October 14, 2008, we borrowed $3,000,000 on the credit facility. During June 2010, we repaid $500,000 on the credit facility. The amount we can borrow against our collateral is limited by FINRA; see footnote 16 to our consolidated financial statements.

Current global economic conditions have resulted in increased volatility in the financial markets. The cost of accessing the credit markets has increased as many lenders and institutional investors have increased interest rates, enacted tighter lending standards, and reduced or ceased to provide funding to borrowers. Adverse changes in the economy could limit our ability to obtain financing from debt or equity sources or could adversely affect the terms on which we may be able to obtain any such financing.

Cash shortfalls currently experienced by PDS and TPL, and continued negative cash flows incurred by PDSG, will have an adverse effect on our liquidity. Accordingly, we are in the process of examining alternatives that could allow for the partnering or divestiture of PDSG. If successful, these measures may provide for a further reduction in expenses and cash use, or additionally in the event of divestiture, cash proceeds.

While our current liquid cash resources as of May 31, 2010, are expected to provide the funds necessary to support our operations through at least the next twelve months, the cash flows from our interest in PDS represents our primary significant source of cash generation. In the event of a decrease or interruption in MMP Portfolio licensing we would incur a significant reduction to our cash position as the revenues from our PDSG subsidiary are insufficient to cover the costs of their operations and the costs of Patriot Scientific Corporation as a whole. Our most significant source of additional liquid cash would likely come from our ARS positions either as a result of redemption, successfully prevailing in our arbitration action against Deutsche Bank Securities, Inc. and affiliates, or the liquidation of some or all of the ARS instruments in negotiated transactions with third parties at a discount to their par value.

Cash Flows From Operating Activities

Cash used in operating activities for the fiscal years ended May 31, 2010, 2009 and 2008 was approximately $7,317,000, $7,165,000 and $19,260,000, respectively. The principal non-cash components of the current fiscal year were: impairment of intangibles and goodwill of approximately $4,627,000 and impairment of investment in affiliated companies of approximately $1,549,000. These items were offset by: net loss of approximately $6,680,000, equity in earnings of affiliates of approximately $4,461,000, and change in deferred taxes of approximately $3,508,000.

Decreases in our net income and equity in earnings of affiliates for the fiscal years ended May 31, 2010, 2009, and 2008 are primarily due to the decrease in our share of earnings in our affiliate PDS.

Cash Flows From Investing Activities

Cash provided by investing activities for the fiscal years ended May 31, 2010, 2009 and 2008 was approximately $11,674,000, $4,993,000 and $10,725,000, respectively. Decreases were primarily due to decreases in distributions received from PDS. Cash used during the fiscal year ended May 31, 2010 included approximately $73,000 in purchases of fixed assets, approximately $613,000 to purchase $33,000 membership units of Talis and $580,000 in capital contributions to PDS and approximately $55,000 in note receivable advances to Avot and $1,950,000 in note receivable advances to TPL.

During fiscal 2008, we used approximately $8,849,000 of cash in net purchases of investments and approximately $800,000 of cash in investments in affiliates and convertible notes. During fiscal 2009 we made no purchases of investments and used approximately $2,874,000 and $2,484,000, respectively, of cash in acquisitions and investments in affiliated companies and convertible notes.

Cash Flows From Financing Activities

Cash provided by financing activities for the fiscal year ended May 31, 2009 was approximately $1,956,000 as compared to cash used in financing activities of approximately $223,000 and $6,647,000, respectively, for the fiscal years ended May 31, 2010 and 2008, respectively. For the fiscal year ended May 31, 2009, cash of approximately $1,127,000 was used to purchase common stock for treasury and cash of approximately $216,000 was used to pay notes payable. Cash received from financing activities during fiscal 2009 consisted of $3,000,000 received on our line of credit and $290,000 received by Holocom on their line of credit facility.

In fiscal year 2010 we used approximately $234,000 to purchase common stock for treasury. In fiscal year 2008 we had used our available cash to repurchase warrants and purchase common stock for treasury.

Capital Resources

Our current position as of May 31, 2010 is expected to provide the funds necessary to support our operations through at least the next twelve months.

Contractual Obligations and Commitments

A summary of our outstanding contractual obligations at May 31, 2010 is as follows:

Contractual Cash Obligations	Total Amounts Committed		1-3 Years		3-6 Years

Operating leases – facilities	$	325,531	$	325,531	$	-
Officer bonus	$	145,875	$	145,875	$	-
Repayments of long term debt	$	3,122,144	$	500,000	$	2,622,144

Our line of credit facility with a balance of approximately $3,122,000 at May 31, 2010 does not have a specified maturity date and terms of the agreement state the credit facility is available to us “as long as needed” subject to the collateral value of our ARS. During June 2010, we paid $500,000 on the credit facility.

RECENT ACCOUNTING PRONOUNCEMENTS

Recent Accounting Pronouncements

In June 2009, the Financial Accounting Standards Board (“FASB”) revised the authoritative guidance for the consolidation of variable interest entities. The objective of this authoritative guidance is to improve financial reporting by enterprises involved with variable interest entities. The revised authoritative guidance is effective as of the beginning of each reporting entity’s first annual reporting period that begins after November 15, 2009. We will adopt this guidance on June 1, 2010, and have not determined the effect of the adoption on our consolidated financial statements.

In July 2009, the FASB revised the authoritative guidance relating to software revenue recognition to exclude all tangible products containing both software and non-software components that function together to deliver the product’s essential functionality. The revised authoritative guidance is effective for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010, and shall be applied on a prospective basis. Earlier application is permitted as of the beginning of an entity’s fiscal year provided it has not previously issued financial statements for any period within that year. We expect to adopt this guidance on June 1, 2011, and have not determined the effect of the adoption on our consolidated financial statements.

In September 2009, the FASB revised the authoritative guidance for revenue arrangements with multiple deliverables. This revised authoritative guidance requires companies to allocate revenue in arrangements involving multiple deliverables based on the estimated selling price of each deliverable, even though such deliverables are not sold separately either by the company itself or other vendors. This revised authoritative guidance eliminates the requirement that all undelivered elements must have objective and reliable evidence of fair value before a company can recognize the portion of the overall arrangement fee that is attributable to items that already have been delivered. As a result, the new guidance may allow some companies to recognize revenue on transactions that involve multiple deliverables earlier than under current requirements. This revised authoritative guidance is effective for revenue arrangements entered into or materially modified in fiscal years beginning on or after December 15, 2009. Early adoption is permitted at the beginning of a company’s fiscal year. We will adopt this guidance on June 1, 2010, and have not determined the effect of the adoption on our consolidated financial statements.

ITEM 7A.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The primary objective of our investment activities is to maintain surplus cash in accounts that provide a high level of funds accessibility in large, respected financial institutions with asset safety as a primary consideration. Accordingly, we maintain our cash and cash equivalents with high quality financial institutions. Amounts deposited with these institutions may exceed federal depository insurance limits.

Cash and Cash Equivalents

We maintain cash and cash equivalents in institutional money market accounts. In general, money market funds are not subject to interest rate risk because the interest paid on these funds fluctuates with the prevailing interest rate.

Our commercial checking account is linked to a sweep account. This sweep account is maintained by our financial institution in an offshore account located in the Cayman Islands. This sweep account is a deposit liability of our financial institution, the funds are not insured by the Federal Deposit Insurance Corporation (“FDIC”); in liquidation the funds have a lesser preference than deposits held in the United States, and the funds are subject to cross-border risks.

Auction Rate Securities

Our exposure to market risk for changes in interest rates relates primarily to our auction rate securities. During the fiscal year ended May 31, 2009, investment banks were reporting an inability to successfully obtain subscribers for high credit quality auction rate securities. As of the date of this filing, we held such auction rate securities with a par value totaling $5.2 million that failed to sell at auction. During June 2009, September 2009, December 2009 and May 2010, auction rate securities with a par value of $750,000, $2,500,000, $350,000 and $2,500,000, respectively, were redeemed by the issuers at par value. During June 2010 auction rate securities with a par value of $350,000 were redeemed by the issuers at par. In the event we need to access funds invested in these auction rate securities we will not be able to liquidate these securities until a future auction of these securities is successful, they are refinanced and redeemed by the issuers, or a buyer is found outside of the auction process. The investments consist of student loan auction rate instruments issued by various state agencies pursuant to the Federal Family Educational Loan Program (“FFELP”). These investments are of high credit quality and the AAA credit ratings of the investments have been reaffirmed since May 2010. These instruments are collateralized in excess of the underlying obligations, are insured by the various state educational agencies, and are guaranteed by the Department of Education as an insurer of last resort.

At May 31, 2010, the fair value of our auction rate securities was estimated at $5.1 million based on a valuation by Houlihan Smith & Company, Inc. which reflects a temporary unrealized loss of $416,165. We have concluded that the unrealized losses on these investments are temporary because (i) we believe that the decline in market value and absence of liquidity that has occurred is due to general market conditions, (ii) the auction rate securities continue to be of a high credit quality and interest is paid as due and (iii) we do not intend to sell our auction rate securities before we are able to recover our cost basis and it is more likely than not that we will not have to sell our auction rate securities before recovery of our cost basis. Since this valuation adjustment is deemed to be temporary, it did not affect our earnings for the fiscal years ended May 31, 2010 and 2009.

We are not currently able to predict how long these investments will remain illiquid, and as such, they have been classified as long-term investments in marketable securities in the accompanying consolidated balance sheets at May 31, 2010 and 2009.

The fair value of our long-term investments in marketable securities could change significantly in the future and we may be required to record other-than-temporary impairment charges or additional unrealized losses in future periods.

We do not believe that the illiquidity of these investments will materially impact our ability to fund our working capital needs, capital expenditures or other business requirements.

During June 2008, we obtained a credit facility which provides for financing of the par value balance of our outstanding auction rate securities based on collateral limits set by FINRA. The facility is collateralized by the full value of the outstanding auction rate securities, required no origination fee, and when drawn upon will bear interest at the federal funds rate plus 3%. On October 14, 2008, we drew $3,000,000 on the credit facility. During June 2010, we paid $500,000 on the credit facility.

Disclosure controls and procedures are controls and other procedures designed to ensure that the information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

As of the end of the period covered by this report, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13(a)-15(e) of the Exchange Act). Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective to achieve their stated purpose as of May 31, 2010, the end of the fiscal year covered by this report. However, there is no assurance that our disclosure controls and procedures will operate effectively under all circumstances.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f).

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). Based on our evaluation under the framework in Internal Control — Integrated Framework our management concluded that our internal control over financial reporting was effective as of May 31, 2010.

Our internal controls over financial reporting as of May 31, 2010 have been audited by KMJ Corbin & Company LLP, our independent registered public accounting firm, as stated in their report which appears herein.

Changes in Internal Controls over Financial Reporting

Based on our management’s evaluation (with the participation of our Chief Executive Officer and Chief Financial Officer) of internal control over financial reporting as required by Rule 13a-15 under the Exchange Act, we have not identified any changes in our internal control over financial reporting that occurred during the fourth fiscal quarter ended May 31, 2010, that have or are reasonably likely to materially affect our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Patriot Scientific Corporation

We have audited Patriot Scientific Corporation and subsidiaries’ (the "Company") internal control over financial reporting as of May 31, 2010, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting included in Item 9A. Our responsibility is to express an opinion on the effectiveness of the Company's internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal controls over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with accounting principles generally accepted in the United States of America, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

In our opinion, Patriot Scientific Corporation maintained, in all material respects, effective internal control over financial reporting as of May 31, 2010, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Patriot Scientific Corporation as of May 31, 2010 and 2009, and the related consolidated statements of operations, stockholders' equity and comprehensive income (loss) and cash flows for each of the three years in the period ended May 31, 2010 and our report dated August 16, 2010 expressed an unqualified opinion on those consolidated financial statements.

Board Leadership Structure

Our bylaws provide that the Chairman of the Board shall preside over all meetings of the Board of Directors. Our bylaws also state that the Chairman of the Board shall serve as the Chief Executive Officer unless determined otherwise by our Board. Since October 5, 2009 our Chief Financial Officer has served as our interim CEO and our Board has not appointed a Chairman of the Board. During meetings of our Board of Directors, Mr. Johnson, an independent director, serves as Chairman of the Board.

Our independent directors meet in executive sessions without management present to evaluate whether management is performing its responsibilities in a manner consistent with the direction of the Board. Additionally, all Board committee members are independent directors. The committee chairs have authority to hold executive sessions without management present. The Board has determined that its current structure is in the best interests of the Company and its stockholders. We believe the independent nature of the Audit Committee and the Compensation Committee as well as the practice of the independent directors regularly meeting in executive session without Mr. Flowers present ensures that the Board maintains a level of independent oversight of management that is appropriate for the Company.

Board Risk Oversight

Our Board oversees and maintains our governance and compliance processes and procedures to promote the conduct of our business in accordance with applicable laws and regulations and with the highest standards of responsibility, ethics and integrity. As part of its oversight responsibility, our Board is responsible for the oversight of risks facing the Company and seeks to provide guidance with respect to the management and mitigation of those risks. Our board also delegates specific areas of risk to the Audit Committee which is responsible for the oversight of risk policies and processes relating to our financial statements and financial reporting processes. The Audit Committee reviews and discusses with management and the independent auditors significant risks and exposures to the company and steps management has taken or plans to take to minimize or manage such risks. The Audit Committee meets in executive session with our Chief Financial Officer and our independent auditor at each regular meeting of the Audit Committee.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires our directors, executive officers and persons who beneficially own 10% or more of a class of securities registered under Section 12 of the Exchange Act to file reports of beneficial ownership and changes in beneficial ownership with SEC. Directors, executive officers and greater than 10% stockholders are required by the rules and regulations of the SEC to furnish us with copies of all reports filed by them in compliance with Section 16(a).

Based solely on our review of copies of the Forms 3, 4 and 5 and amendments thereto, furnished to us by the persons required to make such filings during the 2010 fiscal year, and our own records, we believe that from the period June 1, 2009 through May 31, 2010, Mr. Falk failed to file timely two Form 4s to report changes in beneficial ownership as required by Section 16(a) of the Exchange Act.

Code of Ethics

We have adopted a Code of Ethics that applies to our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. Our Code of Ethics is available on our website at www.ptsc.com under the link “Investors” and “Management Team”.

Audit Committee

We have an audit committee established in accordance with Section 3(a)(58)(A) of the Exchange Act, currently comprised of: Gloria H. Felcyn (Committee Chair) and Carlton M. Johnson, Jr. Each member of our Audit Committee (the “Audit Committee”) is independent as defined under the applicable rules of the SEC and NASDAQ Stock Market LLC (“NASDAQ”) listing standards. The Board of Directors has determined that Gloria H. Felcyn, who serves on the Audit Committee, is an “audit committee financial expert” as defined in applicable SEC rules.

Director Legal Proceedings

During the past ten years, no director, executive officer or nominee for our Board of Directors has been involved in any legal proceedings that are material to an evaluation of their ability or integrity to become our director or executive officer

ITEM 11.

EXECUTIVE COMPENSATION

Overview

In this section we review our plans and programs for compensating our executive officers who are named in the Summary Compensation Table that appears under the caption “Executive Compensation.”

Compensation Discussion and Analysis

Compensation Philosophy and Objectives. The Compensation Committee of our Board of Directors (the “Compensation Committee”) is committed to the general principle that overall executive compensation should be commensurate with corporate performance, the performance of the individual executive officers, and the attainment of predetermined corporate goals. The primary objectives of our executive compensation program are to:

●

reward the achievement of desired corporate and individual performance goals;

●

provide compensation that enables us to attract and retain key executives; and

●

provide compensation opportunities that are linked to our performance and that directly link the interests of executives with the interests of stockholders.

We balance our executive compensation program to provide a level of compensation opportunity that is competitive with those offered by companies in comparable industries and of comparable development, complexity and size. In determining compensation levels, the Compensation Committee considers a number of factors, including corporate performance, both separately and in relation to other companies competing in our markets, the individual performance of each executive officer, comparative compensation surveys concerning compensation levels and stock grants at other companies, our historical compensation levels and stock awards, and the overall competitive environment for executives and the level of compensation necessary to attract and retain key executives. Compensation levels may be greater or less than competitive levels in comparable companies based upon factors such as annual and long-term corporate and individual performance.

Executive Compensation Program Components. Our executive compensation program consists of base salary, bonuses and stock options. The particular elements of the compensation program are discussed more fully below.

Base Salary

Base salary levels of executives are determined by the potential impact of the individual on the Company and corporate performance, the skills and experience required by the position, the individual performance and potential of the executive, and market data for comparable positions in companies in comparable industries and of comparable development, complexity and size. Base salaries for executives are generally evaluated and adjusted annually. The Compensation Committee has the discretionary authority to adjust such base level salaries based on our actual and projected performance, including factors related to revenue and profitability. In considering our performance in fiscal year 2010 in relation to the performance of other companies in our industry generally, we feel that the current compensation levels of our executive officers are appropriate.

The Omnibus Reconciliation Act of 1993 added Section 162(m) to the Internal Revenue Code limiting corporate deductions to $1,000,000 for certain types of compensation paid to the chief executive officer and each of the four other most highly compensated executives of publicly held companies. We do not believe that we will pay “compensation” within the meaning of Section 162(m) to such executive officers in excess of $1,000,000 in the foreseeable future. Therefore, we do not have a policy at this time regarding qualifying compensation paid to our executive officers for deductibility under Section 162(m), but will formulate a policy if compensation levels ever approach $1,000,000.

Base salary is the only element of compensation that is used in determining the amount of contributions permitted under our 401(k) plan.

Bonuses

The Compensation Committee may establish the goals and measurements for bonuses to align executive pay with achievement of critical strategies and operating goals. The targets for executive officers have been set at 50% of base salary for our Chief Executive Officer and 40% of base salary for other officers, except as otherwise reflected in individual employment contracts.

The Compensation Committee typically determines that the bonus shall take into consideration the achievement of revenue and profit goals and the achievement of specific strategic objectives.

During the fiscal year 2010, we paid Mr. Flowers a $62,500 discretionary bonus per his employment contract and we accrued $145,875 for Mr. Flowers’ interim CEO bonus. During the fiscal year 2009, we paid the following bonuses to our named executive officers: $250,000 to Mr. Goerner, our former CEO, for completion of his interim period on November 29, 2008, $50,000 to Mr. Flowers, our CFO, per his employment contract and $53,750 to Mr. Bibeau, our former Vice President of Business Development, for his milestones relating to our merger and acquisition activities. During fiscal 2008, we accrued $83,000 and $11,000, respectively, for Mr. Goerner and Mr. Bibeau’s bonuses as shown in the Summary Compensation Table.

Stock Options

We use stock options to enable key executives to participate in a meaningful way in our success and to link their interests directly with those of stockholders. The number of stock options we grant to executives is based upon a number of factors, including base salary level and how such base salary level relates to those of other companies in our industry, the number of options previously granted, individual and corporate performance during the year, and the size and nature of option packages granted to comparable employees in comparable companies.

We set the exercise price of stock options at the fair market value of our Common Stock on the date of grant. Fair market value is determined as the closing price of our stock on the grant date. We do not backdate options or grant options retroactively. We do not loan funds to employees to enable them to exercise stock options.

All of our stock options are granted at the sole discretion of the Board of Directors or the Compensation Committee. Named executive officers may be granted stock options in accordance with terms of their employment contracts.

For the fiscal year ended May 31, 2010, no named executive officers received options to purchase our Common Stock.

Benefits

Named executive officers also participate in our benefit plans on the same terms as other employees. These plans include medical and dental insurance, as well as life and disability insurance.

Retirement Plan

We maintain a 401(k) plan for all eligible employees. Pursuant to the plan, we provide a 50% match on the first 6% of a participant’s compensation. Matching contributions vest over a three year period. Participants choose to invest their account balances from a selection of funds provided by the plan fiduciary. None of the investment options are in our stock.

Severance Benefits

We provide severance benefits to ease our executives’ transition due to an unexpected employment termination by us due to on-going changes in our employment needs. Our Chief Financial Officer is entitled to severance benefits as specified in his employment contract. Our former Chief Executive Officer was entitled to severance benefits per his Separation Agreement accordingly, during the fiscal year 2010 we accrued $145,833 to be paid out in the seven months following his separation date of October 5, 2009. During fiscal 2010, we also provided our former Vice President of Business Development a lump-sum severance payment of $12,981 in connection with his separation on October 5, 2009.

Change in Control

We provide change in control benefits as an incentive to our key employees to remain with us despite uncertainties while a transaction is under consideration or pending. Our Chief Financial Officer is entitled to change in control benefit payments as specified in his employment contract which is described below.

Management’s Role in Establishing Compensation

Our named executive officers do not determine or approve any element or component of their own base salary, annual incentive awards, long-term incentives or other aspects of compensation. The named executive officers do provide input and make recommendations to the Compensation Committee with respect to the compensation of officers who report to them. These recommendations are based on various factors, including individual contribution and performance, company performance, labor market conditions, complexity and importance of roles and responsibilities, reporting relationships, retention needs and internal pay relationships.

Compensation Committee Report

The Compensation Committee reviewed and discussed our Compensation Discussion and Analysis with management. Based upon such review and discussions, the Committee recommended to the Board of Directors that our Compensation Discussion and Analysis be included in this Annual Report on Form 10-K for the fiscal year ended May 31, 2010.

1.	On October 5, 2009, in connection with Mr. Flowers’ appointment as Interim CEO, the Compensation Committee authorized his unvested options to immediately vest.

Employment Contracts

In connection with Mr. Flowers’ appointment as Chief Financial Officer on September 17, 2007, we entered into an Employment Agreement (the “Flowers Agreement”) with Mr. Flowers for an initial 120-day term if not terminated pursuant to the Flowers Agreement, with an extension period of one year and on a day-to-day basis thereafter. Pursuant to the Flowers Agreement, Mr. Flowers’ initial base salary was $225,000 per year and he is eligible to receive an annual merit bonus of up to 50% of his base salary, as determined in the sole discretion of the Board of Directors. Effective October 1, 2008 and October 5, 2009, Mr. Flowers’ base salary was increased to $231,750 and $291,750, respectively. Also pursuant to the Flowers Agreement and on the date of the Flowers Agreement, Mr. Flowers received a grant of non-qualified stock options to purchase 150,000 shares of our Common Stock and a grant of non-qualified stock options to purchase 600,000 shares of our Common Stock. Mr. Flowers’ right to exercise the foregoing stock options became fully vested on October 9, 2009, in connection with his appointment as Interim CEO. The Flowers Agreement also provides for Mr. Flowers to receive customary employee benefits, including health, life and disability insurance.

Pursuant to the Flowers Agreement, if Mr. Flowers is terminated without cause or resigns with good reason within the first two years of employment, he is entitled to receive an amount equal to his annual base salary for the greater of (i) 6 months or (ii) the period remaining in the extended one-year term. If Mr. Flowers is terminated without cause or resigns with good reason any time after two years of continuous employment, he is entitled to receive an amount equal to 12 months of his annual base salary. Mr. Flowers is also entitled to certain payments upon a change of control of the Company if the surviving corporation does not retain him. All such payments are conditional upon the execution of a general release.

We had an employment agreement with Mr. Goerner. Under terms his Separation Agreement, Mr. Goerner was paid outplacement assistance of $3,500 and a severance payment of $145,833. The severance payment was paid in bi-weekly installments over a seven month period that ended May 2010. We also reimbursed Mr. Goerner for a portion of his health and dental insurance premiums totaling $8,613 during the seven month period ended May 2010 according to provisions in his Separation Agreement.

We had an employment agreement with Mr. Turley for a one-year term. Upon Mr. Turley’s resignation on February 28, 2008, he was entitled to a severance payment of $95,192, which was paid bi-weekly over a seven month period that ended in August 2008.

We had an employment agreement with Mr. Pohl. Under terms of the agreement, upon his retirement as CEO on June 5, 2007, Mr. Pohl was paid a severance payment of $100,000 payable in bi-weekly installments over a six month period that ended December 2007.

We had an employment agreement with Mr. Sweeney. Under the terms of the agreement, Mr. Sweeney was paid a salary of $1,125 per day, subject to increase at our sole discretion. Mr. Sweeney was also entitled to a cash bonus, stock options and severance pay, in each case, as determined by the Compensation Committee in its sole discretion. During the course of Mr. Sweeney’s employment with us, Mr. Sweeney remained a partner of Tatum CFO Partners, LLP (“Tatum”). As a partner of Tatum, Mr. Sweeney shared with Tatum a portion of his economic interest in any stock options or equity bonus that we paid him, to the extent specified in a Part-Time Engagement Resources Agreement between us and Tatum. Mr. Sweeney was eligible for our 401(k) plan and for vacation and holidays consistent with our policy as it applies to senior management.

Potential Payments on Termination or Change in Control

As described above under Employment Contracts, Mr. Flowers is entitled to severance payments should he be terminated without cause or resign for good reason as specified in his employment contract.

In order to be entitled to the severance payments, Mr. Flowers must sign a separation agreement which includes a general release of all claims and a non-disparagement agreement. Payments are to be made by us according to our payroll schedule for a minimum period of twelve months.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE

Transactions With Directors, Executive Officers and Principal Stockholders

The Audit Committee reviews and approves all transactions between us and any of our directors, executive officers, director nominees or any immediate family member of any such person.

There were no transactions, or series of transactions during the fiscal year ended May 31, 2010, nor are there any currently proposed transactions, or series of transactions, to which we are a party, in which the amount exceeds $120,000, and in which to our knowledge any director, executive officer, nominee, five percent or greater stockholder, or any member of the immediate family of any of the foregoing persons, has or will have any direct or indirect material interest other than as described below.

Director Independence

Our Board of Directors has determined that a majority of the members of, and nominees to, our Board of Directors qualify as “independent,” as defined by the listing standards of NASDAQ. Consistent with these considerations, after review of all relevant transactions and relationships between each director and nominee, or any of his or her family members, and us, our senior executive management and our independent auditors, the Board of Directors has determined further that all of our directors and nominees are independent under the listing standards of NASDAQ. In making this determination, the Board of Directors considered that there were no new transactions or relationships between its current independent directors and the Company, its senior management and its independent auditors since last making this determination. Each member of our Audit Committee, and each member of the Compensation Committee of our Board of Directors, is independent as defined by the listing standards of NASDAQ.

ITEM 14.

PRINCIPAL ACCOUNTANT FEES AND SERVICES

Pursuant to the Policy on Engagement of Independent Auditor, the Audit Committee is directly responsible for the appointment, compensation and oversight of the independent auditor. The Audit Committee pre-approves all audit services and non-audit services to be provided by the independent auditor and has approved 100% of the audit, audit-related and tax fees listed below. The Audit Committee may delegate to one or more of its members the authority to grant the required approvals, provided that any exercise of such authority is presented at the next Audit Committee meeting for ratification.

Each audit, non-audit and tax service that is approved by the Audit Committee will be reflected in a written engagement letter or writing specifying the services to be performed and the cost of such services, which will be signed by either a member of the Audit Committee or by one of our officers authorized by the Audit Committee to sign on our behalf.

The Audit Committee will not approve any prohibited non-audit service or any non-audit service that individually or in the aggregate may impair, in the Audit Committee’s opinion, the independence of the independent auditor.

In addition, since January 1, 2003, our independent auditor may not provide any services to our officers or Audit Committee members, including financial counseling or tax services.

Notes to Consolidated Financial Statements

1. Organization and Business

Patriot Scientific Corporation (the “Company”, “PTSC”, “we”, “us”, or “our”), was organized under Delaware law on March 24, 1992 and is the successor by merger to Patriot Financial Corporation, a Colorado corporation, incorporated on June 10, 1987. In 1997, we acquired Metacomp, Inc. which we dissolved in September 2008 and in June 2005 we entered into a joint venture agreement with Technology Properties Limited, Inc. (“TPL”) to form Phoenix Digital Solutions, LLC (“PDS”). In March 2007, we became the primary beneficiary of Holocom, Inc. (formerly known as Scripps Secured Data, Inc.) (“Holocom”), a variable interest entity (‘VIE”) and we were required to consolidate Holocom effective in March 2007. Due to a re-consideration event on May 1, 2009, we deconsolidated Holocom (see Note 14). During May 2008, we acquired an interest in Talis Data Systems, LLC (“Talis”), a Delaware LLC that produces multi-domain hardware. During the third quarter of fiscal 2010, Talis was dissolved. In September 2008, we acquired Patriot Data Solutions Group, Inc. (formerly known as Crossflo Systems, Inc.) (“PDSG”), a California company. During the fiscal year 2009, we acquired preferred shares of Avot Media, Inc. (“Avot”) an innovator of video transcoding and near real-time streaming to web-enabled mobile devices. In March 2010, Avot sold substantially all of its assets. In January 2010, we sold the assets of Verras Medical, Inc. and in August 2010 we sold the Vigilys business line both formerly associated with PDSG.

Our primary operating activity has been as an intellectual property company that licenses our jointly held patent portfolio technology, through our interest in PDS, to others and litigates against those who infringe upon the patent portfolio technology. Through the acquisition of PDSG, our primary operating activity is providing data sharing services and secure data solutions.

Holocom develops and manufactures network-security hardware to government, military, and other high-security facilities.

2. Reclassifications

We have reclassified our loss on sale of fixed assets as presented in the Other income (expense) section of our 2009 and 2008 consolidated financial statements to selling, general and administrative expenses. Such reclassifications have no impact on our financial position or results of operations.

Noncontrolling interest (previously shown as minority interest) is reported below net income (loss) under the heading “Income attributable to noncontrolling interest” in the consolidated statements of operations.

Basis of Consolidation (continued)

The consolidated statement of operations for the fiscal year ended May 31, 2009 includes our accounts, those of our wholly owned subsidiary PDSG, Plasma Scientific Corporation and the VIE for which we were the primary beneficiary for the period in fiscal 2009 (June 1, 2008 through April 30, 2009). All significant intercompany accounts and transactions have been eliminated. During September 2008, we dissolved our majority owned inactive subsidiary, Metacomp, Inc.

The consolidated statement of operations for the fiscal year ended May 31, 2008 includes our accounts, those of our wholly owned inactive subsidiaries, Metacomp, Inc. and Plasma Scientific Corporation and the VIE for which we were the primary beneficiary. All significant intercompany accounts and transactions have been eliminated.

Consolidation of Affiliate

We have adopted the authoritative guidance for identifying VIEs and determining when we should include the assets, liabilities, noncontrolling interests and results of activities of a VIE in our consolidated financial statements.

A VIE is a corporation, partnership, limited liability corporation, trust or any other legal structure used to conduct activities or hold assets that either (1) has an insufficient amount of equity to carry out its principal activities without additional subordinated financial support, (2) has a group of equity owners that are unable to make significant decisions about its activities, or (3) has a group of equity owners that do not have the obligation to absorb losses or the right to receive returns generated by its operations.

We are required to consolidate a VIE if we have an ownership, contractual or other financial interest in the VIE that obligates us to absorb a majority of the risk of loss from the VIE’s activities, or we are entitled to receive a majority of the VIE’s residual returns (if no party absorbs a majority of the VIE’s losses), or both. A variable interest holder that consolidates the VIE is called the primary beneficiary. Upon consolidation, the primary beneficiary generally must initially record all of the VIE’s assets, liabilities, and noncontrolling interests at fair value and subsequently account for the VIE as if it were consolidated based on majority voting interest.

Beginning with the quarter ended May 31, 2007, we consolidated Holocom as Holocom was deemed a VIE and we determined that we were the primary beneficiary of Holocom. During July 2008, Holocom obtained a credit facility for up to $300,000 from a third party, the credit facility term extended to May 1, 2009, and was guaranteed by us. As a result of our guarantee on the third party credit facility, we maintained a variable interest in Holocom. Upon expiration of the credit facility on May 1, 2009, we deconsolidated Holocom as we are no longer deemed to be the primary beneficiary. We were recording our investment in Holocom under the cost method until it was fully impaired at May 31, 2010 (see Note 13).

Financial Instruments and Concentrations of Credit Risk

Financial instruments that potentially subject us to concentrations of credit risk consist principally of cash, cash equivalents, investments in marketable securities, and trade accounts receivable.

At times, our balance of cash maintained with our bank may exceed the Federal Deposit Insurance Corporation’s (“FDIC”) insured limit of $250,000. At May 31, 2010 and 2009, neither PTSC’s nor PDSG’s cash and cash equivalents balances subject to FDIC insurance exceeded the FDIC limit. At May 31, 2010 and 2009, PTSC’s cash and cash equivalents balance consisting of money market accounts not subject to FDIC insurance was $10,095,240 and $5,987,845, respectively. We limit our exposure of loss by maintaining our cash with financially stable financial institutions. When we have excess cash, our cash equivalents are placed in high quality money market accounts with major financial institutions. We believe this investment policy limits our exposure to concentrations of credit risk.

Investments in marketable securities consist of AAA rated student loan auction rate instruments issued by various state agencies pursuant to the Federal Family Educational Loan Program (“FFELP”). These investments are collateralized in excess of the underlying obligations, are insured by the various state educational agencies, and are guaranteed by the Department of Education as an insurer of last resort.

Concentrations of credit risk with respect to accounts receivable are limited due to the wide variety of customers and markets which comprise our customer base, as well as their dispersion across many different geographic areas. We routinely assess the financial strength of our customers and, as a consequence, believe that our accounts receivable credit risk exposure is limited. Generally, we do not require collateral or other security to support customer receivables. As of May 31, 2010, PDSG’s customers A and B accounted for 71.5% and 22.1%, respectively, of gross accounts receivable. As of May 31, 2009, PDSG’s customers A, B and C accounted for 59.7%, 17.5% and 13.4%, respectively, of gross accounts receivable.

Fair Value of Financial Instruments

Our financial instruments consist principally of cash and cash equivalents, investments in marketable securities, accounts receivable, accounts payable, accrued expenses and long term debt. The carrying value of these financial instruments, other than the investments in marketable securities, approximates fair value because of the immediate or short-term maturity of the instruments. The interest rate on our long term debt is based on market indices.

Our investments in marketable securities consist of auction rate securities. Historically, the carrying value of auction rate securities approximated fair value due to the frequent resetting of the interest rate. While we continue to receive interest payments on our auction rate investments despite failed auctions, we believe the carrying value of these auction rate securities no longer approximates fair value. We estimated the fair value of these securities at May 31, 2010 and 2009 based on an independent valuation performed by Houlihan Smith & Company Inc., an independent valuation firm. In determining the estimate of fair value, consideration was given to credit quality, estimated cash flows, and estimated probabilities of default, auction failure and a successful auction at par or repurchase at par. Based on this valuation, we recorded a net temporary recovery of $382,320 in other comprehensive loss at May 31, 2010 which represents the gross valuation recovery of $635,446, net of the related tax expense of $253,126 at May 31, 2010. For the fiscal year ended May 31, 2009, we recorded a net temporary impairment of $408,697 in other comprehensive income at May 31 2009 which represents the gross valuation adjustment loss of $679,287, net of the related tax benefit of $270,590 at May 31, 2009 (see Note 6).

Cash Equivalents, Restricted Cash, and Short-Term Marketable Securities

For purposes of balance sheet classification and the statements of cash flows, we consider all highly liquid investments acquired with a maturity of three months or less to be cash equivalents.

Restricted cash and cash equivalents at May 31, 2009 consist of two savings accounts required to be held as collateral for corporate credit card accounts. At May 31, 2010 we have one savings account held as collateral for our corporate credit card account.

At May 31, 2010 and 2009, PTSC’s short-term marketable securities in the amount of $12,105 and $58,292, respectively, consist of accrued interest receivable on our auction rate securities which is receivable semi-annually according to the terms specified in each auction rate security instrument. These values are reported at cost, which approximate fair market value.

Accounts Receivable

At May 31, 2010 and 2009, our accounts receivable consists of the accounts of PDSG. PDSG’s accounts receivable consist of trade receivables recorded at the original invoice amount, less an estimated allowance for uncollectible accounts of which there was none at May 31, 2010 and 2009. Trade receivables are periodically evaluated for collectibility based on past credit histories with customers and their current financial condition. Changes in the estimated collectibility of trade receivables are recorded in the results of operations for the period in which the estimate is revised. Trade receivables that are deemed uncollectible are offset against the allowance for uncollectible accounts.

Work-In-Process

At May 31, 2010 and 2009, work-in-process represents the excess of recognized revenue over invoices to customers on PDSG’s current contracts in progress.

Investments in Marketable Securities

We determine the appropriate classification of our investments at the time of purchase and reevaluate such designation at each balance sheet date. Our investments in marketable securities have been classified and accounted for as available-for-sale based on management’s investment intentions relating to these securities. Available-for-sale marketable securities are stated at fair market value based on valuation by Houlihan Smith & Company, Inc. Unrealized gains and losses, net of deferred taxes, are recorded as a component of other comprehensive income (loss). We follow the authoritative guidance to assess whether our investments with unrealized loss positions are other than temporarily impaired. Realized gains and losses and declines in value judged to be other than temporary are determined based on the specific identification method and are reported in other income, net in the consolidated statements of operations.

Notes to Consolidated Financial Statements (Continued)

Property, Equipment and Depreciation

Property and equipment are stated at cost and are depreciated using the straight-line method over the estimated useful lives of the assets, ranging from three to five years. Major betterments and renewals are capitalized, while routine repairs and maintenance are charged to expense when incurred.

Business Combinations and Intangible Assets Including Goodwill

Business combinations are accounted for using the purchase method of accounting and accordingly, the assets and liabilities of the acquired entities are recorded at their estimated fair values at the acquisition date. Goodwill represents the excess of the purchase price over the fair value of net assets, including the amount assigned to identifiable intangible assets. Obtaining information needed to finalize the fair value of the acquired assets and liabilities takes time and frequently occurs over several quarters. Accordingly, it is common for initial fair value estimates to be subsequently revised. The results of operations of acquired businesses are included in our consolidated financial statements from the acquisition date.

Identifiable intangible assets with finite lives are amortized on a straight-line basis over their estimated useful lives. They are reviewed for impairment if indicators of potential impairment exist. Goodwill is tested for impairment on an annual basis.

Impairment of Goodwill, Intangible Assets and Other Long-Lived Assets

Management assesses the recoverability of our long-lived assets by determining whether the carrying value can be recovered through projected undiscounted future cash flows. The amount of long-lived asset impairment, if any, is measured based on fair value and is charged to operations in the period in which long-lived asset impairment is determined by management.

Based on a combination of factors occurring during fiscal 2010 and fiscal 2009, including the current economic environment, market conditions, and decline in value of our common stock, management has determined that indicators for impairment of goodwill and intangible assets existed.

The inability of PDSG to meet its business plan and the general economic environment were indicators of potential impairment on our goodwill and intangible assets, accordingly at May 31, 2009 and during fiscal 2010, management determined that goodwill was impaired by approximately $1,096,000 and $236,000, respectively, for the fiscal years ended May 31, 2010 and 2009 and PDSG’s intangibles were impaired by approximately $3,530,000 for the fiscal year ended May 31, 2010. We have recorded these as impairments of goodwill on our consolidated statements of operations for the fiscal years ended May 31, 2010 and 2009 and as an impairment of purchased intangibles on our consolidated statement of operations for the fiscal year ended May 31, 2010.

Investments in Affiliated Companies

We have a 50% interest in PDS (see Note 13). This investment is accounted for using the equity method of accounting since the investment provides us the ability to exercise significant influence, but not control, over the investee. Significant influence is generally deemed to exist if we have an ownership interest in the voting stock of the investee of between 20% and 50%, although other factors, such as representation on the investee’s board of directors, are considered in determining whether the equity method of accounting is appropriate. Under the equity method of accounting, the investment, originally recorded at cost, is adjusted to recognize our share of net earnings or losses of the investee which is presented in the consolidated statements of operations in the caption “Equity in earnings of affiliated companies, net” and also is adjusted by contributions to and distributions from PDS.

Effective June 1, 2010, we adopted new authoritative guidance for consolidation of variable interest entities (see Recent Accounting Pronouncements).

Investments in Affiliated Companies (continued)

We had a 39.4% interest in Talis (see Note 13). Prior to the write-off of our investment in Talis during the quarter ended August 31, 2009, we were accounting for our investment using the equity method of accounting. Under the equity method of accounting, the investment, originally recorded at cost, was adjusted to recognize our share of net earnings or losses of the investee and was presented in the consolidated statements of operations in the caption “Equity in earnings of affiliated companies, net.” In December 2009, Talis was dissolved.

We owned 37.1% of the preferred stock of Avot (see Note 13). Prior to the write-off of our investment in Avot during the quarter ended November 30, 2009, we were accounting for our investment at cost since we did not have the ability to exercise significant influence over the operating and financial policies of Avot. During March 2010, Avot sold substantially all of its assets and we collected our note receivable and accrued interest.

We own 100% of the preferred stock of Holocom (see Note 13). Prior to impairment, this investment was accounted for at cost since we did not have the ability to exercise significant influence over the operating and financial policies of Holocom.

During the fiscal year ended May 31, 2010, management determined that: our investment in Talis was impaired by approximately $680,000, our investment in Avot was impaired by approximately $433,000 and that the inability of Holocom to meet its business plan, raise capital, and the general economic environment were indicators of impairment on our investment and accordingly we wrote off our investment in the preferred stock of Holocom amounting to approximately $435,000. We have recorded these as “Impairment of investment in affiliated companies, net” on our consolidated statement of operations for the fiscal year ended May 31, 2010.

The inability of Avot to meet its business plan, to raise capital, and the general economic environment were indicators of impairment on our investment, accordingly at May 31, 2009, management determined that our investment in Avot was impaired by approximately $867,000. We have recorded this as an impairment of investment in affiliated company on our consolidated statement of operations for the fiscal year ended May 31, 2009.

Treasury Stock

We account for treasury stock under the cost method and include treasury stock as a component of stockholders’ equity.

Comprehensive Income (Loss)

Comprehensive income (loss) as presented in the consolidated statements of stockholders’ equity includes unrealized gains and losses which are excluded from the consolidated statements of operations. For the fiscal years ended May 31, 2010 and 2009, this amount included unrealized gains and losses on investments classified as available-for-sale. The amount is presented net of fiscal year 2010 tax-related expense of $253,126 and fiscal year 2009 tax-related benefit of $270,589.

Revenue Recognition

Historically, we recognized revenue from the sale of our microprocessor chips upon shipment to the customer, at which time title transferred and we had no further obligations. We discontinued the sale of our microprocessor chips during the first quarter of fiscal 2009.

Revenue from technology license agreements is recognized at the time a contract is entered into, the license method is determined (paid-in-advance or on-going royalty), and the customer is provided with the licensed technology, if applicable. Fees for maintenance or support are recorded on a straight-line basis over the underlying period of performance.

Notes to Consolidated Financial Statements (Continued)

Revenue Recognition (continued)

PDSG sells software and services to end users primarily through relationships with systems integrators and prime contractors. PDSG recognizes revenue in accordance with authoritative guidance for the software industry. PDSG’s revenue is derived primarily from the following sources: (i) software licensing, (ii) related professional services, and (iii) post contract customer support (“PCS”) agreements. PCS agreements typically include software updates, on a when and if available basis, telephone and Internet access to technical support personnel. Software updates provide customers with rights to unspecified software product upgrades and to maintenance releases and patches released during the term of the support period. Revenue for support services is recognized on a straight-line basis over the support period.

Effective June 1, 2010, we adopted new authoritative guidance for revenue arrangements with multiple deliverables (see Recent Accounting Pronouncements).

The majority of PDSG’s contracts with customers, including systems integrators and prime contractors, are multiple element arrangements which contain professional services that are considered essential to the functionality of the other elements of the arrangement. PDSG accounts for revenue on these arrangements according to authoritative guidance for contract accounting. Under this guidance, PDSG recognizes revenue based on progress towards contract completion measured by actual hours incurred in relation to the estimate of total expected hours. PDSG measures these revenues by applying the contract-specific estimated percentage of completion to the total contract amount for software and professional services. PDSG routinely updates the estimates of future hours for agreements in process and reports any cumulative effects of such adjustments in current operations. PDSG immediately recognizes any loss expected on these contracts when it is projected that loss is probable.

In certain situations where PDSG’s customer contracts contain acceptance criteria or other conditions that are deemed adverse to the probability for collection, revenues recognized are limited by the amount of cash already collected.

Prior to its deconsolidation, Holocom recognized revenue upon shipment of its product or upon receipt of its product by the customer when shipped FOB destination and recognized revenue on its short-term installation contracts as time and materials costs were incurred.

Holocom maintained agreements with stocking distributors. These agreements provided for a limited product warranty for a period of one year from the date of sale to the end user. The warranty did not cover damage to the product after it was delivered to the distributor. Holocom’s stocking distributor agreements also allowed limited rights to periodic stock rotation. These rotation rights allowed for the exchange of a percentage of distributor inventory for replacement products of the distributor’s choosing.

Shipping and Handling

Shipping and handling fees billed to customers are required to be classified as revenue, and shipping and handling costs are required to be classified as either cost of sales or disclosed in the notes to the financial statements. Holocom included shipping and handling fees billed to customers in net sales. Holocom included shipping and handling costs associated with inbound freight and unreimbursed shipping to customers in cost of sales.

Selling, General and Administrative

Selling expenses include items such as sales salaries and commissions, marketing and advertising costs and consultant services. Advertising costs are expensed as incurred and were not significant for the fiscal years ended May 31, 2010, 2009 and 2008. General and administrative expenses include costs for items such as salaries, legal and accounting, and insurance.

F-13

Patriot Scientific Corporation

Notes to Consolidated Financial Statements (Continued)

Research and Development

Research and development costs are expensed as incurred and primarily include payroll and related benefit costs and contractor fees.

Income Taxes

We recognize deferred income taxes for the tax consequences in future years of differences between the tax basis of assets and liabilities and their financial reporting amounts at each year end based on enacted tax laws and statutory tax rates applicable to the periods in which the differences are expected to affect taxable income. We establish valuation allowances when necessary to reduce deferred tax assets to the amount we expect to realize.

Earnings Per Share

Basic earnings per share includes no dilution and is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflect the potential dilution of securities that could share in the earnings of an entity. At May 31, 2010, 2009 and 2008, potential common shares of 5,962,917, 9,725,000 and 2,645,000, respectively, related to our outstanding warrants and options were not included in the calculation of diluted income per share as they had an anti-dilutive effect. Had we reported net income for the year ended May 31, 2010, an additional 410,000 shares of common stock would have been included in the calculation of diluted income per share.

In connection with our acquisition of Crossflo, which is now a part of PDSG, we issued 2,844,630 escrow shares that are contingent upon certain representations and warranties made by Crossflo at the time of the merger agreement (see Note 19). We exclude these escrow shares from the basic earnings (loss) per share calculations and include the escrowed shares in the diluted earnings per share calculations.

The following presents the basic and diluted earnings (loss) per share for the years ended May 31, 2010, 2009 and 2008:

	Year Ended May 31, 2010
	Numerator (Loss)		Denominator (Shares)	Per Share Amount

Use of Estimates

The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities in the consolidated financial statements and accompanying footnotes. Actual results could differ from those estimates. On an ongoing basis we evaluate our estimates, including, but not limited to: the realizability of accounts and notes receivable, valuation of work-in-process, fair values of investments in marketable securities, the use, recoverability, and /or realizability of certain assets, including investments in affiliated companies, intangible assets, goodwill, deferred tax assets, and stock-based compensation.

Noncontrolling Interest

In fiscal 2010, we adopted authoritative guidance which requires us to present noncontrolling interest (previously shown as minority interest) in our fiscal 2009 and 2008 consolidated statements of operations under the heading “Income attributable to noncontrolling interest” instead of separately presented as a reduction to net income. Such noncontrolling interest resulted from the accounting for the acquisition of a noncontrolling interest in Holocom. Noncontrolling interest represents a partially owned subsidiary’s income, losses, and components of other comprehensive income (loss) which should be attributed to the controlling and noncontrolling interests or other parties with a right or obligation that affects the attribution of comprehensive income or loss, on the basis of their contractual rights or obligations, if any, otherwise, on the basis of ownership interests.

During the fiscal year ended May 31, 2009, a reconsideration event occurred and we de-consolidated Holocom. Accordingly, no noncontrolling interest is reported in our fiscal 2009 consolidated balance sheet.

F-15

Patriot Scientific Corporation

Notes to Consolidated Financial Statements (Continued)

Stock-Based Compensation

Stock-based compensation expense recognized during the year is based on the grant date fair value of the portion of share-based payment awards ultimately expected to vest during the year. As stock-based compensation expense recognized in the consolidated statements of operations is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Forfeiture rates are based on historical forfeiture experience and estimated future employee forfeitures.

Recent Accounting Pronouncements

In June 2009, the Financial Accounting Standards Board (“FASB”) revised the authoritative guidance for the consolidation of variable interest entities. The objective of this authoritative guidance is to improve financial reporting by enterprises involved with variable interest entities. The revised authoritative guidance is effective as of the beginning of each reporting entity’s first annual reporting period that begins after November 15, 2009. We adopted this guidance on June 1, 2010 and are evaluating the effect of the adoption on our consolidated financial statements.

In July 2009, the FASB revised the authoritative guidance relating to software revenue recognition to exclude all tangible products containing both software and non-software components that function together to deliver the product’s essential functionality. The revised authoritative guidance is effective for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010, and shall be applied on a prospective basis. Earlier application is permitted as of the beginning of an entity’s fiscal year provided it has not previously issued financial statements for any period within that year. We adopted this guidance on June 1, 2010, and are evaluating the effect of the adoption on our consolidated financial statements.

In September 2009, the FASB revised the authoritative guidance for revenue arrangements with multiple deliverables. This revised authoritative guidance requires companies to allocate revenue in arrangements involving multiple deliverables based on the estimated selling price of each deliverable, even though such deliverables are not sold separately either by a company itself or other vendors. This revised authoritative guidance eliminates the requirement that all undelivered elements must have objective and reliable evidence of fair value before a company can recognize the portion of the overall arrangement fee that is attributable to items that already have been delivered. As a result, the new guidance may allow some companies to recognize revenue on transactions that involve multiple deliverables earlier than under current requirements. This revised authoritative guidance is effective for revenue arrangements entered into or materially modified in fiscal years beginning on or after December 15, 2009. Early adoption is permitted at the beginning of a company’s fiscal year. We adopted this guidance on June 1, 2010, and are evaluating the effect of the adoption on our consolidated financial statements.

4. Acquisitions

Collectively, the three acquisitions below completed during the fiscal year ended May 31, 2009 are known as Patriot Data Solutions Group, Inc. (“PDSG”).

Crossflo Systems, Inc.

On September 1, 2008, we acquired all of the outstanding shares of Crossflo Systems, Inc. (“Crossflo”). The results of Crossflo’s operations have been included in our consolidated financial statements since that date. Crossflo markets data sharing services and products primarily to the public safety/government sector. Crossflo’s flagship product is the Crossflo DataExchange (“CDX”). CDX is a commercial off-the-shelf middleware designed for inter-agency and cross-domain data sharing which allows end users to selectively share information and rapidly connect disparate data sources across multiple platforms.

The aggregate purchase price was $10,257,604, including $2,850,790 of cash, $824,600 of convertible notes and common stock valued at $6,582,214. The value of the 26,988,455 shares issued was based on the average closing price of our common stock on the Electronic Bulletin Board as reported by NASDAQ over the ten trading days immediately preceding September 1, 2008.

Acquisitions (continued)

This transaction was accounted for in accordance with FASB authoritative guidance for business combinations and we have allocated the total purchase price to tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values.

Purchase consideration:
Price per share	$	0.24389
Number of common shares issued		26,988,455
Value of shares issued		6,582,214
Cash paid, including acquisition costs		2,850,790
Conversion of convertible notes and accrued interest receivable		824,600
	$	10,257,604

Allocation of purchase consideration:
Tangible assets acquired:
Cash	$	272,509
Accounts receivable		101,179
Work-in-process		11,658
Deferred tax assets		2,173,443
Property and equipment		49,399
Prepaid expenses and other		36,590
Identifiable intangible assets acquired:
Customer contracts – open orders		63,600
Maintenance agreements		75,400
Technologies and processes		5,932,400
Goodwill		1,668,630
Total assets acquired		10,384,808
Liabilities assumed:
Current liabilities		(127,204	)
	$	10,257,604

The fair values assigned to identifiable intangible assets acquired were based on an appraisal using estimates and assumptions determined by management. The fair values of the customer contracts, maintenance agreements and technologies and processes were determined using an income approach.

None of our acquired intangible assets were assigned to research and development assets. The acquired intangible assets of $6,071,400 had a weighted-average useful life of approximately 8 years. The intangible assets that made up that amount included customer contracts of $63,600 (0.75 year weighted-average useful life), maintenance agreements of $75,400 (4 year weighted-average useful life) and technologies and processes of $5,932,400 (8 year weighted-average useful life). During the quarter ended November 30, 2009 intangibles were impaired and the fair value of Crossflo’s technology was reduced to $1,860,000 (see Note 5).

Goodwill in the amount of $1,668,630 was assigned to the Crossflo segment. This amount is not deductible for income tax purposes. During the fiscal year ended May 31, 2009 goodwill was impaired by approximately $236,000. During the quarter ended November 30, 2009 goodwill was impaired by approximately $790,000 (see Note 5).

Acquisitions (continued)

The net deferred tax asset is a result of purchase accounting. The deferred tax asset results from Crossflo’s net operating loss carryforwards that can be used to offset consolidated taxable income in future periods, offset by the deferred tax liability which is the result of future amortization expenses attributable to the acquired intangible assets which will not be deductible for income tax purposes.

The deferred tax asset was calculated as follows:

	Net Operating Loss Carryforward		Tax Rate		Deferred Tax Asset
Federal	$	11,995,697		35%	$	4,198,494
California		7,810,697		5.746%		448,802
	$	19,806,394			$	4,647,296

The deferred tax liability was calculated as follows:

Identifiable intangible assets acquired	$	6,071,400

Verras Medical, Inc.

On December 1, 2008, Crossflo acquired the assets of Verras Medical, Inc. (“Verras”). Verras does business as Iameter and under the Iameter name provides a healthcare software tool called Sherlock™ for hospitals and physician groups to assess the quality of care delivery against state and federal healthcare standards to help realize quality improvements and reduced costs.

The aggregate purchase price was $536,225, including $503,071 of cash and $33,154 of note receivable conversion (see Note 8).

This transaction was accounted for in accordance with FASB guidance for business combinations and we have allocated the total purchase price to tangible and identifiable intangible assets acquired based on their estimated fair values.

Purchase consideration:
Cash paid, including acquisition costs	$	103,071
Non-interest bearing payable		400,000

Acquisitions (continued)

On August 1, 2010 PDSG sold the Vigilys business line for payments totaling at least $60,000. $6,000 was payable at closing, and minimum installments of $12,000 are due on the first and second anniversary dates of closing and $30,000 is to be paid on the third anniversary date of closing.

5. Goodwill and Other Intangible Assets

Goodwill originating from acquisitions is not amortized and is tested for impairment on an annual basis and between annual tests based on certain circumstances.

Purchased intangible assets were being amortized over a period of 9 months to 10 years. After impairment, the technology of PDSG is currently being amortized over 81 months.

Management’s plan of restructuring on October 5, 2009 and the continuing inability of PDSG to meet its business plan were indicators of potential impairment on our intangible assets. Accordingly, during the fiscal year ended May 31, 2010, it was determined that intangibles were impaired by approximately $3,530,000. We have recorded this as an impairment of purchased intangibles on our consolidated statement of operations for the fiscal year ended May 31, 2010.

The following tables present details of our other intangible assets and related accumulated amortization balances, which were recorded as a result of business combinations and asset purchases:

Goodwill and Other Intangible Assets (continued)

We have included the amortization expense and related impairment charges on intangible assets that relate to products sold in cost of sales. We have included amortization expense associated with our and Holocom’s patents in selling, general and administrative expense on our consolidated statement of operations for the eleven months ended April 30, 2009 and during the fiscal year ended May 31, 2008.

The amortization expense related to intangible assets was as follows:

	Fiscal Year Ended		Fiscal Year Ended		Fiscal Year Ended
	May 31, 2010		May 31, 2009		May 31, 2008
Amortization of intangible assets included in:

2012		275,556
2013		275,556
2014		275,556
2015		275,556
Thereafter		344,442
Total	$	1,722,222

Management’s plan of restructuring on October 5, 2009 and the continuing inability of PDSG to meet its business plan were indicators of potential impairment on our goodwill. Accordingly, during the fiscal year ended May 31, 2010, management determined that goodwill was impaired by an aggregate of approximately $1,096,000. We have recorded this as an impairment of goodwill on our consolidated statement of operations for the fiscal year ended May 31, 2010.

The inability of PDSG to meet its business plan and the general economic environment were indicators of potential impairment on our goodwill and intangible assets, accordingly at May 31, 2009, management determined that goodwill was impaired by approximately $236,000. We have recorded this as an impairment of goodwill on our consolidated statement of operations for the fiscal year ended May 31, 2009.

The changes in the carrying amount of goodwill for the fiscal years ended May 31, 2010 and 2009 are as follows:

Balance, June 1, 2008	$	-
Goodwill of Crossflo acquired (see Note 4)		1,668,630

6. Fair Value Measurements

We follow authoritative guidance to account for our financial assets and liabilities at fair value. Under this authoritative guidance we are required to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. We determine fair value based on quoted prices when available or through the use of alternative approaches, such as discounting the expected cash flows using market interest rates commensurate with the credit quality and duration of the investment or valuations by third party professionals. The three levels of inputs that we may use to measure fair value are:

Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

Level 2: Quoted prices in markets that are not active or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability; and

Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e. supported by little or no market activity).

The following table represents our financial instruments subject to fair value measurement and the valuation approach applied to each class of security:

		Quoted Prices in Active Markets Level 1				Significant Other Observable Inputs Level 2				Significant Unobservable Inputs Level 3				Balance as of May 31, 2010
Auction rate securities		$	—			$	—			$	5,133,835			$	5,133,835

The valuation of these securities is based on Level 3 unobservable inputs which consist of recommended fair values provided by Houlihan Smith & Company, Inc. As a result of the estimated fair value, we have determined that there is a temporary impairment in the valuation of these securities of $416,165 at May 31, 2010. We have recorded the temporary impairment as an unrealized loss in accumulated other comprehensive loss at May 31, 2010, which represents the cumulative gross valuation adjustment of $416,165, net of the related tax effects of $169,171. These securities are held “available-for-sale” in conformity with authoritative guidance and the unrealized loss is included in other comprehensive income in the current period. Due to the uncertainty related to the liquidity in the auction rate security market, we have classified these auction rate securities as long-term assets on the consolidated balance sheets.

Crossflo Systems, Inc.

On May 30, 2008, we purchased a secured convertible promissory note from Crossflo with a face amount of $400,000. Interest accrued on the note at a rate of 5.25% per annum and was due with principal at the earlier of (i) September 30, 2008, (ii) consummation of an equity financing by Crossflo which closed on or before September 30, 2008, in which Crossflo sold and issued shares of its convertible preferred stock resulting in aggregate gross proceeds to Crossflo of at least $2.5 million (a “Qualified Financing”), or (iii) upon or after the occurrence of an event of default, as defined. The note was secured by substantially all assets of Crossflo.

Notes to Consolidated Financial Statements (Continued)

Notes Receivable (continued)

The Crossflo note receivable was convertible at our option, at any time prior to September 30, 2008, into shares of Crossflo’s Series F convertible preferred stock equal to 4% of Crossflo’s then issued and outstanding equity securities. In addition, the entire principal was automatically convertible into shares of Crossflo’s Series F convertible preferred stock at the closing of a Qualified Financing. The number of shares of Series F convertible preferred stock to be issued upon automatic conversion of the principal amount was the greater of (i) 4% of Crossflo’s then issued and outstanding equity securities, and (ii) the principal amount divided by the per share purchase price paid by the investors participating in the Qualified Financing. Upon an event of default, as defined, the principal amount of the note may have been converted into shares of Crossflo’s Series F convertible preferred stock equal to 4% of Crossflo’s then issued and outstanding equity securities. Upon maturity on September 30, 2008, the principal amount of the note was to be automatically converted into shares of Crossflo’s Series F convertible preferred stock equal to 4% of Crossflo’s then issued and outstanding equity securities.

Upon conversion of the principal amount of the note pursuant to the above, we were entitled to receive shares of Crossflo’s common stock equal to all accrued and unpaid interest divided by $0.20.

In connection with our purchase of the secured convertible promissory note from Crossflo, we also received a warrant to purchase 200,000 shares of Crossflo’s common stock at $0.20 per share. Notwithstanding the foregoing, in the event a Qualified Financing was not consummated prior to September 30, 2008, the warrant would have been exercisable into 1,000,000 shares of Crossflo’s common stock at $0.20 per share. The warrant was exercisable until the earlier of (i) October 11, 2012, (ii) the closing of an underwritten public offering by Crossflo pursuant to a registration statement under the Securities Act, (iii) the closing of a merger or other reorganization by Crossflo with another entity, or (iv) the closing of a sale of all or substantially all of the assets of Crossflo. The value attributed to the warrant was insignificant, and accordingly, the principal amount of the loan was recorded as a note receivable at May 31, 2008.

At May 31, 2008, the balance of the note receivable was $400,115, including accrued interest receivable of $115 recognized during the year ended May 31, 2008. During the fiscal year 2009, interest of $5,293 accrued on the note. The note and accrued interest was converted during our acquisition of Crossflo on September 1, 2008.

On August 8, 2008, we purchased a secured convertible promissory note from Crossflo with a face amount of $417,750. This note carried the same terms and provisions as the May 30, 2008 convertible promissory note. Accrued interest receivable on the note from August 8, 2008 to September 1, 2008 was $1,442. The note and accrued interest was converted during our acquisition of Crossflo on September 1, 2008.

On August 5, 2008, we announced our intent to acquire Crossflo for $10 million comprised of cash and stock with an effective completion date of September 1, 2008, subject to approval by Crossflo’s shareholders. On September 1, 2008, according to provisions of the Merger Agreement, the principal amounts of our secured convertible promissory notes were offset against the shares of stock we provided at closing (see Note 4) and the warrants associated with the notes were cancelled.

Avot Media, Inc.

On August 15, 2008, we purchased a convertible promissory note from Avot with a face amount of $250,000. Interest accrued on the note at a rate of 5% per annum and was due with principal at the earlier of (i) September 1, 2008, (ii) consummation of an equity financing by Avot which closed on or before August 31, 2008 in which Avot sold and issued shares of its convertible preferred stock to Patriot (a “Qualified Financing”) or (iii) upon or after the occurrence of an event of default, as defined substantially all assets of Crossflo. On August 22, 2008, we converted the principal of $250,000 to 2,777,778 shares of Avot’s Series B preferred stock and on September 3, 2008 we received $243 from Avot representing accrued interest on the note.

At May 31, 2009, work-in-process consisting of recognized revenue on PDSG’s current contracts was $193,826 and invoices to customers were $166,547. These amounts are shown on our May 31, 2010 and 2009 balance sheets at net of $136,637 and $27,279, respectively, due to their immateriality.

Investments in Marketable Securities (continued)

As of May 31, 2010 and 2009, we held four and six investments, respectively, that were in an unrealized loss position:

	Continuous Unrealized Loss
	Less than 12 months				12 months or greater
	Fair Value		Unrealized Loss		Fair Value		Unrealized Loss
Auction rate securities	$	-	$	-	$	5,133,835	$	(416,165	)

The following table presents the amortized cost and fair value of our investments in marketable securities classified as available-for-sale at May 31, 2010 and 2009 by contractual maturity:

	May 31, 2010
	Amortized Cost			Fair Value
Maturity
Greater than two years		$	5,550,000		$	5,133,835

	May 31, 2009
	Amortized Cost			Fair Value
Maturity
Greater than two years		$	11,650,000		$	10,598,389

As of May 31, 2010 and 2009, we held auction rate securities with a par value totaling $5.6 and $11.7 million, respectively, which failed to sell at auction. In the event we need to access funds invested in these auction rate securities we would not be able to liquidate these securities until (i) a future auction of these securities is successful, (ii) they are refinanced and redeemed by the issuers, or (iii) a buyer is found outside of the auction process. The investments consist of student loan auction rate instruments issued by various state agencies pursuant to the Federal Family Educational Loan Program (“FFELP”). These investments are of high credit quality and the AAA credit ratings of the investments have been reaffirmed since May 2010. These instruments are collateralized in excess of the underlying obligations, are insured by the various state educational agencies, and are guaranteed by the Department of Education as an insurer of last resort. We have the intent and the ability to hold these investments until the anticipated recovery period.

Due to the uncertainty surrounding the timing of a market recovery, we have classified our auction rate securities as long- term investments in our consolidated balance sheets as of May 31, 2010 and 2009. As a result of temporary declines in the fair value of our auction rate securities, which we attribute to liquidity issues rather than credit issues, we have recorded an unrealized loss of $246,994 in accumulated other comprehensive loss at May 31, 2010, which represents the gross valuation adjustment of $416,165, net of the related tax benefit of $169,171. At May 31, 2009 we recorded an unrealized loss of $629,314 in other comprehensive loss which represented the gross valuation adjustment of $1,051,611, net of the related tax benefit of $422,297.

We will continue to evaluate the fair value of our investments in auction rate securities each reporting period for a potential other-than-temporary impairment.

During June 2008, we obtained a credit facility for as long as needed, which provides for financing up to 50% of the par value balance of our outstanding auction rate securities on that date. The facility is collateralized by the full value of the outstanding auction rate securities, required no origination fee, and if drawn upon will bear interest at the federal funds rate plus 3% (see Note 16).

11. Property and Equipment

Property and equipment consisted of the following at May 31, 2010 and 2009:

	2010			2009
Computer equipment and software	$	92,416		$	118,794
Furniture and fixtures		51,725			52,147
		144,141			170,941
Less: accumulated depreciation and amortization		(107,042	)		(85,466	)
Net property and equipment	$	37,099		$	85,475

Depreciation and amortization expense related to property and equipment was $35,695, $68,457 and $36,359 for the years ended May 31, 2010, 2009 and 2008, respectively.

Prior to the sale of the assets of Verras (see Note 4) we recorded depreciation and amortization expense of $15,377 during the year ended May 31, 2010.

12. License Agreements

In February 2005, we entered into two separate licensing agreements with one customer for our patent portfolio and Ignite microprocessor technology. The aggregate amount of the two licenses was $3,050,000, of which $2,950,000 was for licensing fees and $100,000 was for maintenance services. Maintenance under the agreement was expected to be provided over a period not to exceed four years; which ended in February 2009. Maintenance revenue recognized during the fiscal years ended May 31, 2009 and 2008 was $18,750 and $25,000, respectively. The payment terms of the agreements required aggregate payments of $300,000 at the time of execution, three quarterly payments of $750,000 each on April 1, August 15, and November 15, 2005 and one final payment of $500,000 on February 15, 2006. The $500,000 payment due on February 15, 2006 was paid in March 2006. Total payments received in fiscal 2005 amounted to $1,050,000, and total payments received in fiscal 2006 amounted to $2,000,000. The agreements also provide for the future payment of royalties to us based on sales of product using the Ignite licensed technology. In connection with this license agreement, we became obligated to the co-inventor of the patent portfolio technology for $207,600 pursuant to a July 2004 agreement under which we were obligated to pay a percentage of all patent portfolio licensing proceeds to the co-inventor. The amount due under that license was payable in four installments of $51,900. The co-inventor of the patent portfolio technology filed a lawsuit against us seeking damages and/or enforcement of the July 2004 agreement. We challenged the enforceability of the agreement by counterclaim in that action. On February 14, 2007, a settlement of the litigation was finalized. Terms of the settlement required us to pay $3,400,000 in cash on February 14, 2007 and $3,000,000 on May 1, 2007, which amounted to approximately the debt claimed by the co-inventor to be owed to him under the July 2004 agreement. In addition, the settlement required us to make a donation of $15,000 on February 14, 2007 on behalf of Russell H. Fish III (“Fish”) to Maasai Power and Education Project, Inc., and to pay Fish the equivalent of 4% of 50% of the next $100 million of gross license fees as they are collected by PDS and as distributions are made to us, after excluding the first $20 million collected by PDS after December 1, 2006. Our commitment to make payments to Fish related to such future license revenues was limited to $2 million. During the fiscal year ended May 31, 2008 we recorded $836,400 in settlement and license expenses relating to royalty payments due to the Fish parties. In January 2008, we made the final payment under the Fish settlement agreement.

13. Investments in Affiliated Companies

Phoenix Digital Solutions, LLC

On June 7, 2005, we entered into a Master Agreement (the “Master Agreement”) with TPL, and Charles H. Moore (“Moore”), the co-inventor of the technology which is the subject of the MMP Portfolio of microprocessor patents, pursuant to which the parties resolved all legal disputes between them. Pursuant to the Master Agreement, we and TPL entered into the Limited Liability Company Operating Agreement of PDS (the “LLC Agreement”) into which we and Moore contributed our rights to certain of our technologies.

Investments in Affiliated Companies (continued)

We and TPL each own 50% of the membership interests of PDS, and each of us has the right to appoint one member of the three member management committee. The two appointees are required to select a mutually acceptable third member of the management committee. Pursuant to the LLC Agreement, we and TPL agreed to establish a working capital fund for PDS of $4,000,000, of which our contribution was $2,000,000. The working capital fund increases to a maximum of $8,000,000 as license revenues are achieved. We and TPL are obligated to fund future working capital requirements at the discretion of the management committee of PDS in order to maintain working capital of not more than $8,000,000. Neither we nor TPL are required to contribute more than $2,000,000 in any fiscal year. During the fiscal year ended May 31, 2010 we and TPL each contributed $580,000 to PDS for working capital requirements. Distributable cash and allocation of profits and losses will be allocated to the members in the priority defined in the LLC Agreement.

Pursuant to the Master Agreement, PDS has committed to pay a quarterly amount ranging between $500,000 and $1,000,000 (based upon a percentage of the working capital fund balance of PDS) for supporting efforts to secure licensing agreements by TPL on behalf of PDS. During the fiscal years ended May 31, 2010, 2009 and 2008, PDS paid $1,500,000, $2,869,114 and $2,952,362, respectively, to TPL pursuant to this commitment.

PDS reimburses TPL for payment of all legal and third-party expert fees and other related third-party costs and expenses, and certain internally generated costs as approved on August 17, 2009 and more fully described below. During the fiscal years ended May 31, 2010, 2009 and 2008, PDS paid $3,684,154, $5,851,514, and $12,894,053, respectively, to TPL pursuant to the agreement.

On November 13, 2008, the management committee of PDS resolved to pay TPL 3% of the gross licensing revenue received by PDS for the period June 1, 2008 through May 31, 2009, as reimbursement for certain expenses incurred by TPL in connection with TPL’s activities related to a possible amendment of patent laws in the United States. The aggregate reimbursement under this resolution was not to exceed $1,000,000 for the period June 1, 2008 through May 31, 2009. From November 2008 to May 31, 2009, PDS expensed $571,500 pursuant to this resolution. This amount is not included in the legal and third-party expenses above for fiscal 2009.

On August 17, 2009, the management committee of PDS resolved to pay TPL $500,000 per quarter beginning on June 1, 2009 and continuing through May 31, 2010 relating to TPL’s special work and effort regarding the MMP litigation and U.S. Patent Office re-examinations. In the event that PDS had insufficient funds to make such payments, we were required to advance half of the quarterly amount to PDS. Our advances to PDS were to be without interest and were to be repaid to us no later than May 31, 2010. During the fiscal year ended May 31, 2010, TPL received $1,500,000 from PDS pursuant to this agreement which is included in the fiscal 2010 legal and third-party expenses of PDS above. We did not advance any funds to PDS under this resolution. On May 31, 2010, the resolution terminated.

During April 2010 we filed two separate actions against TPL in the Superior Courts of San Diego and Santa Clara counties. We and TPL had been in negotiations to restructure our relationship, however those negotiations failed and the litigation is proceeding (see Note 19).

Based on our analysis of current authoritative accounting guidance with respect to our investment in PDS, including the notes receivable to TPL described in Note 8, we continue to account for our investment in PDS under the equity method of accounting, and accordingly have recorded our share of PDS’ net income of $4,483,190, $10,192,693 and $19,926,145 during the years ended May 31, 2010, 2009 and 2008, respectively, as an increase in our investment. Cash distributions of $7,557,827, $9,712,417 and $20,288,124 received from PDS during the years ended May 31, 2010, 2009 and 2008, respectively, have been recorded as a reduction in our investment. Cash contributions of $580,000 made during the fiscal year ended May 31, 2010 have been recorded as in increase in our investment. Our investment in PDS of $507,629 and $3,002,267 at May 31, 2010 and 2009, respectively, has been recorded as “Investments in Affiliated Companies”. We have recorded our share of PDS’ net income as “Equity in Earnings of Affiliated Companies, net” in the accompanying consolidated statements of operations for the years ended May 31, 2010, 2009 and 2008.

During the years ended May 31, 2010, 2009 and 2008, TPL entered into licensing agreements with third parties, pursuant to which PDS recorded license revenues of approximately $14,279,000, $29,392,000 and $59,283,000, respectively.

At May 31, 2010, PDS had accounts payable and accrued expense balances of approximately $1,724,000 and $7,000 to TPL and PTSC, respectively. At May 31, 2009, PDS had accounts payable balances of approximately $1,482,000 and $5,500 to TPL and PTSC, respectively.

The condensed balance sheets of PDS at May 31, 2010 and 2009 and statements of income of PDS for the years ended May 31, 2010, 2009 and 2008 are as follows:

Talis Data Systems, LLC

On May 16, 2008, we paid $400,000 to acquire a 15.09% share in Talis, a company that produced multi-domain computer and network security products for government, military, and enterprise customers. Talis developed and marketed PCs incorporating its Datagent security device, a patented, hardware based data security solution that avoids the vulnerability of software–based approaches.

On August 1, 2008, we increased our investment in Talis as a result of purchasing additional membership units offered by Talis for $300,000 as well as acquiring membership units from minority members for $196,500. We also acquired all of the Talis membership units previously held by Holocom for $100,000 in cash and a reduction on their outstanding line of credit of $219,000.

Patriot Scientific Corporation

Notes to Consolidated Financial Statements (Continued)

Investments in Affiliated Companies (continued)

During the fourth quarter of fiscal year 2009, we purchased an additional 185,793 membership units of Talis for $269,399 which brought our ownership share of Talis to 38.9% at May 31, 2009. During June 2009, we purchased 22,414 membership units for $32,500 which increased our ownership share to 39.4%.

The inability of Talis to meet its business plan, raise capital, and the general economic environment were indicators of impairment on our investment, accordingly at August 31, 2009, it was determined that our investment in Talis was impaired by approximately $680,000. We have recorded this as an impairment of investment in affiliated companies on our consolidated statement of operations for the fiscal year ended May 31, 2010.

We were accounting for our investment in Talis under the equity method of accounting. We had recorded our share of Talis’ net loss of $21,706, $488,024 and $8,376 during the fiscal years ended May 31, 2010, 2009 and 2008, respectively, as a decrease in our investment. Our investment in Talis was $669,498 at May 31, 2009 and was recorded as “Investments in Affiliated Companies”. We have recorded our share of Talis’ net loss as “Equity in Earnings of Affiliated Companies” in the accompanying consolidated statements of operations for the years ended May 31, 2010, 2009 and 2008. The carrying value of our investment in Talis after impairment is zero at May 31, 2010. During the third quarter of fiscal 2010 Talis was dissolved.

Due to the immaterial nature of Talis’ operations, no condensed financial statement information will be presented.

Avot Media, Inc.

During the quarter ended August 31, 2008, we invested an aggregate of $1,300,000, including conversion of a note receivable in the amount of $250,000, to obtain 14,444,444 shares of Series B preferred stock issued by Avot, representing 53.3% of the Series B preferred stock and 37.1% of all Avot’s preferred shares issued and outstanding.

We reviewed the Series B Preferred Stock Purchase Agreement and related agreements in addition to evaluating our voting rights for our investment in the preferred stock of Avot, and as such we concluded that we did not have the ability to exercise significant control over Avot. As a result, we were accounting for our investment in Avot at cost.

During March 2009, we entered into a revolving loan note with Avot. At May 31, 2010, the note has been paid in full (see Note 8).

The inability of Avot to meet its business plan, to raise capital, and the general economic environment were indicators of impairment of our investment, accordingly at May 31, 2009, management determined that our investment in Avot was impaired by approximately $867,000. We have recorded this as an impairment of investment in affiliated company on our consolidated statement of operations for the fiscal year ended May 31, 2009.

In September 2009, we entered into an agreement with Avot in which Avot developed a software package for PDSG’s Vigilys product. Terms of the agreement required PDSG to pay Avot four milestone payments of $50,000 each on September 1, October 1, November 1 and December 1, 2009. In connection with the agreement, Avot issued us 1,000,000 warrants to purchase shares of Avot’s common stock, with an exercise price of $0.05 per share and a 36 month exercise period. The warrants were issued in four 250,000 installments consistent with the milestone payments. The value attributed to the warrants was insignificant.

During the quarter ended November 30, 2009 we wrote off $433,333 which represented the remaining fair value of our preferred stock investment in Avot. We have presented the $433,333 as an impairment of investment in affiliated companies on our consolidated statements of operations for the fiscal year ended May 31, 2010.

During March 2010, Avot sold substantially all of its assets and we collected our note receivable. There was not adequate consideration to redeem any portion of our preferred stock investment which had been fully written off during the fiscal quarters ending in May and November 2009.

Our investment in Avot as impaired was $433,333 at May 31, 2009 and has been recorded as “Investments in Affiliated Companies” on our consolidated balance sheet at May 31, 2009.

Scripps Secured Data, Inc. (d/b/a Holocom, Inc.)

On February 2, 2007, we invested an aggregate of $370,000 in convertible preferred stock, representing all of the issued preferred stock and a 46% ownership interest, of and in Holocom, a California corporation that manufactures products that protect information transmitted over secure networks. The investment consisted of certain assets we contributed to Holocom valued at $250,000 and cash of $120,000. The investment is represented by 2,100,00 shares of convertible preferred stock, and the shares are convertible at our option into shares of Holocom’s common stock on a one-to-one basis. The convertible preferred stock entitles us to receive non-cumulative dividends at the per annum rate of $0.04 per share, when and if declared by the Board of Directors of Holocom. The investment in Holocom’s convertible preferred stock also entitles us to a liquidation preference of $0.40 per share, plus an amount equal to all declared but unpaid dividends.

We reviewed the Preferred Stock Purchase Agreement and related agreements to determine whether our convertible preferred stock investment in Holocom was in substance an investment in common stock pursuant to authoritative guidance. We also evaluated our voting rights pursuant to other agreements with Holocom and, when considered together with authoritative guidance, we believe that we do not have the ability to exercise significant influence over Holocom. As a result, we are accounting for our investment in Holocom at cost.

During March 2007, we entered into a revolving line of credit with Holocom which caused us to have a variable interest in Holocom and we were required to consolidate Holocom as a variable interest entity. Prior to initial consolidation, we recognized a $126,746 impairment loss on our preferred stock investment for the losses of Holocom for the period February 2007 through March 26, 2007. During May 2009, we deconsolidated Holocom due to a re-consideration event (see Note 14). At May 31, 2009, our investment in Holocom was $435,182 and has been recorded as “Investments in Affiliated Companies” on our consolidated balance sheet at May 31, 2009.

Management determined that the inability of Holocom to meet its business plan, raise capital, and the general economic environment were indicators of impairment on our investment. At May 31, 2010, we wrote off our investment in the preferred stock of Holocom amounting to $435,182. We have presented the $435,182 as an impairment of investment in affiliated companies on our consolidated statement of operations for the fiscal year ended May 31, 2010.

We review our investments in affiliated companies to determine whether events or changes in circumstances indicate that the carrying amounts may not be recoverable. The primary factors we consider in our determination are the financial condition, operating performance and near term prospects of the investees. If a decline in value is deemed to be other than temporary, we would recognize an impairment loss.

14. Deconsolidation of Variable Interest Entity

As stated in Note 13, in February 2007, we invested an aggregate of $370,000 in Holocom for 2,100,000 shares of convertible preferred stock. On March 27, 2007, we entered into an 18-month revolving line of credit with Holocom for a maximum amount of $500,000. As a result of the line of credit, we had a variable interest in Holocom, a variable interest entity, and we had determined that we were the primary beneficiary as we absorbed more than half of the variable interest entity’s expected losses. On August 29, 2008 Holocom paid the remaining balance due on the March 2007 line of credit and provided us notice effectively terminating the line of credit on August 29, 2008. During July 2008, Holocom obtained a credit facility for up to $300,000 from a third party, the facility’s term extended to May 1, 2009, and was guaranteed by us. As a result of our guarantee on the third party credit facility, which we were not contractually required to provide, we maintained a variable interest in Holocom as we are obligated under the guarantee to repay the third party should Holocom default on the credit facility. During May 2009, Holocom paid the balance due on the July 2008 facility, releasing our guarantee. As a result of this re-consideration event, we are no longer the sole source of financial support and the primary beneficiary for Holocom; accordingly on May 1, 2009 we deconsolidated Holocom from our financial results.

Short Term

During July 2008, Holocom obtained a credit facility for up to $300,000 from a third party, at an interest rate based on the Wall Street Journal Prime plus 1% (floating) with a floor of 6%. The credit facility term extended to May 1, 2009, and was guaranteed by us. At April 30, 2009, the balance on the credit facility was $290,000 at an interest rate of 6%. During May 2009, Holocom paid the balance due.

Long Term

Total warrants outstanding	325,000	550,000	300,000

Share-based Compensation Summary of Assumptions and Activity

The fair value of stock-based awards to employees and directors is calculated using the Black-Scholes option pricing model, even though this model was developed to estimate the fair value of freely tradable, fully transferable options without vesting restrictions, which differ significantly from our stock options. The Black-Scholes model also requires subjective assumptions, including future stock price volatility and expected time to exercise, which greatly affect the calculated values. The expected term of options granted is derived from historical data on employee exercises and post-vesting employment termination behavior. The risk-free rate selected to value any particular grant is based on the U.S. Treasury rate that corresponds to the pricing term of the grant effective as of the date of the grant. The expected volatility for the fiscal years ended May 31, 2010, 2009 and 2008 is based on the historical volatilities of our common stock. These factors could change in the future, affecting the determination of stock-based compensation expense in future periods.

	Year Ended May 31, 2010		Year Ended May 31, 2009		Year Ended May 31, 2008

Expected term		5 yrs		5 yrs		5 yrs

Options outstanding at June 1, 2009		10,210,000		$	0.39
Options granted		670,000		$	0.18
Options exercised		(100,000	)	$	0.07

Options exercisable at May 31, 2010		5,000,108		$	0.45		1.74	$	-

The weighted average grant date fair value of options granted during the fiscal years ended May 31, 2010, 2009 and 2008 was $0.15, $0.14 and $0.32 per option, respectively. The total intrinsic value of options exercised during the fiscal years ended May 31, 2010, 2009 and 2008 was $9,550, $11,000 and $562,150, respectively, based on the differences in market prices on the dates of exercise and the option exercise prices.

The aggregate intrinsic value in the table above represents the differences in market price at the close of the fiscal year ($0.09 per share on May 31, 2010) and the exercise price of outstanding, in-the-money options (those options with exercise prices below $0.09) on May 31, 2010.

As of May 31, 2010, there was $49,427 of total unrecognized compensation cost related to employee stock option compensation arrangements. That cost is expected to be recognized on a straight-line basis over the next 36 months.

The following table summarizes employee and director stock-based compensation expense for PTSC and employee stock-based compensation expense for PDSG for the fiscal years ended May 31, 2010, 2009 and 2008, which was recorded as follows:

	Year Ended		Year Ended		Year Ended

Total	$	227,717	$	405,747	$	502,770

During the eleven months ended April 30, 2009 and the fiscal year ended May 31, 2008, Holocom recognized $6,328 and $7,201, respectively, of employee, consultant and director stock-based compensation expense.

During the fiscal year ended May 31, 2010, we expensed $857 relating to warrants issued during the current fiscal year and we recognized an adjustment of ($6,932) relating to the forfeiture of warrants during the current fiscal year. During the fiscal year ended May 31, 2009 we expensed $6,932 relating to warrants issued during the fiscal year. We incurred no such expense during the fiscal year ended May 31, 2008.

Income Taxes (continued)

Deferred tax assets and liabilities reflect the net tax effect of temporary differences between the carrying amount of assets and liabilities for financial reporting purposes and amounts used for income tax purposes. Significant components of our deferred tax assets are as follows as of May 31:

	2010			2009
Current deferred tax assets (liabilities):
State taxes	$	(34,509	)	$	184,143
Accrued expenses		73,182			101,329

Total net long-term deferred tax asset		5,911,732			2,843,677
Net deferred tax asset	$	6,384,439		$	3,129,149

On September 1, 2008, we acquired 100 percent of the outstanding shares of Crossflo (see Note 4). As a result of this transaction, we set up a deferred tax asset related to Crossflo’s net operating loss carryforwards that can be used to offset consolidated taxable income in the future. At May 31, 2009, the entire $542,525 above, is a partial valuation allowance on some deferred assets of Crossflo, as management has not determined that it is more likely than not that these deferred tax assets will be realized.

We anticipate carrying back a federal net operating loss of approximately $1,394,000 to the tax year ending May 31, 2009. We have federal and state net operating loss carryforwards available to offset future taxable income of approximately $14,281,000 and $14,966,000, respectively, at May 31, 2010. These carryforwards begin to expire in the years ending May 31, 2023 and 2013, respectively. The state of California has suspended NOL deductions for taxable years beginning in 2008 or 2009 for taxpayers with business income of $500,000 or more.

On June 1, 2007, we adopted authoritative guidance which defines criteria that an individual tax position must meet for any part of the benefit of that position to be recognized in a company’s financial statements and also provides guidance on measurement, derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The adoption of this guidance did not result in any cumulative effect adjustment to retained earnings. Interest and penalties, if any, related to unrecognized tax benefits are recorded in income tax expense. As of May 31, 2010, we are subject to U.S.

Income Taxes (continued)

Federal income tax examinations for the tax years May 31, 1993 through May 31, 2009, and we are subject to state and local income tax examinations for the tax years May 31, 2001 through May 31, 2009 due to the carryover of net operating losses from previous years.

The table below summarizes our liability relating to unrecognized tax benefits under the authoritative guidance:

Balance at May 31, 2009	$	-
Increase in unrecognized tax benefit liability		-
Decrease in unrecognized tax benefit liability		-
Accrual of interest related to unrecognized tax benefits		7,000
Balance at May 31, 2010	$	7,000

Our liability relating to unrecognized tax benefits has been presented net of our prepaid income taxes on our consolidated balance sheet at May 31, 2010.

Our continuing practice is to recognize accrued interest and penalties related to unrecognized tax benefits as a component of tax expense. This policy did not change as a result of our adoption of the authoritative guidance on June 1, 2007. We do not expect our unrecognized tax benefits to change significantly over the next twelve months.

401(k) Plan

Patriot and PDSG have retirement plans that comply with Section 401(k) of the Internal Revenue Code. All employees are eligible to participate in the plans. Patriot matches 50% of each participant’s voluntary contributions, subject to a maximum contribution of 6% of the participant’s compensation. Patriot’s participants vest 33% per year over a three year period in their contributions. Patriot’s matching contributions during the fiscal years ended May 31, 2010, 2009 and 2008 were $18,242, $17,474 and $9,596, respectively. PDSG does not match participant voluntary contributions.

Employment Contracts

On June 5, 2007, Mr. Pohl, our outgoing chief executive officer retired. As a result, we recorded a severance charge of $100,000 during the fiscal year 2008 based on terms of his employment agreement which provided for salary continuation.

In connection with Mr. Turley’s appointment as President and Chief Executive Officer, and commencing on June 5, 2007, we entered into an employment agreement with Mr. Turley for a one-year term. Pursuant to the agreement, if Mr. Turley was terminated without cause, he was entitled to his then current salary level for the remaining term of his agreement conditional upon the execution of a general release. On February 28, 2008, Mr. Turley resigned. As a result, we recorded a one-time severance charge of $95,192 during the fiscal year 2008 in full discharge of all remaining obligations to Mr. Turley.

In connection with Mr. Flowers’ appointment as the Chief Financial Officer, and commencing on September 17, 2007, we entered into an employment agreement with Mr. Flowers for an initial 120-day term if not terminated pursuant to the agreement, with an extension period of one year and on a continuing basis thereafter. Pursuant to the agreement, if Mr. Flowers is terminated without cause or resigns with good reason any time after two years of continuous employment, he is entitled to receive an amount equal to 12 months of his annual base salary. Mr. Flowers is also entitled to certain payments upon a change of control of the Company if the surviving corporation does not retain him. All such payments are conditional upon the execution of a general release.

In connection with Mr. Goerner’s appointment as Interim President and Chief Executive Officer, and commencing on February 29, 2008, we entered into an employment agreement with Mr. Goerner for an initial 120-day term if not terminated pursuant to the agreement, with an extension period of one year and on a continuing basis thereafter. Pursuant to the agreement, if Mr. Goerner was terminated without cause within the first year of employment, after the initial 120-day term, he was entitled to receive an amount equal to his base salary for the period remaining in the agreement. Payments were conditional upon the execution of a general release. In connection with management’s restructuring plan on October 7, 2009, we entered into a Separation Agreement with Mr. Goerner which required us to pay his base salary for the next seven months in exchange for a general release of claims against us. During the fiscal year 2010 we recorded a one-time severance charge of $145,833 pursuant to the Separation Agreement. At May 31, 2010 we have satisfied all payments under the Separation Agreement.

Guarantees and Indemnities

We have made certain guarantees and indemnities, under which we may be required to make payments to a guaranteed or indemnified party. We indemnify our directors, officers, employees and agents to the maximum extent permitted under the laws of the State of Delaware and California for PDSG. In connection with our facility leases, we have indemnified our lessors for certain claims arising from the use of the facilities. The duration of the guarantees and indemnities varies, and in many cases is indefinite. These guarantees and indemnities do not provide for any limitation of the maximum potential future payments we could be obligated to make. Historically, we have not been obligated to make any payments for these obligations and no liabilities have been recorded for these guarantees and indemnities in the accompanying consolidated balance sheets.

Pursuant to the acquisition of Crossflo, we have agreed to indemnify the former owners of Crossflo for certain claims or losses resulting from any untrue, allegedly untrue or misleading statement made in a registration statement, prospectus or similar document.

Bonuses

In connection with the acquisition of Crossflo, retention bonuses were to be paid to individuals who were Crossflo employees pre-merger who remain with PDSG until March 1, 2010. In connection with the acquisition of Vigilys, a retention bonus was to be paid to a key employee who remains with PDSG until March 27, 2010. The projected liability for such bonuses was $75,000. These liabilities were being accrued ratably over the retention periods. During March 2010 retention bonuses in the amount of $75,000 were paid to qualified key employees.

By the terms of his employment contract, our CFO, who also currently serves as our interim CEO, is eligible to earn an annual bonus equivalent to 50% of his base salary. In connection with management’s restructuring plan on October 5, 2009, our Compensation Committee determined that this bonus would be payable at the end of the interim period. The projected liability for such bonus is $145,875 and has been recorded on our consolidated balance sheet in “Accrued expenses and other” at May 31, 2010.

Escrow Shares

As stated in Note 4, in connection with our acquisition of Crossflo, in the event that there is not an adequate number of shares remaining in the escrow account one year from September 1, 2008 (the closing date of the merger agreement between Crossflo and Patriot) to satisfy distribution to Crossflo stockholders in accordance with the terms of the Escrow Agreement, we are required to make up any difference in cash.

On August 31, 2009, we gave notice to the former shareholders of Crossflo and Union Bank of California (the “Escrow Agent”) under Section 2.5 of the Agreement and Plan of Merger between us and Crossflo (the “Agreement”), outlining damages incurred by us in conjunction with the acquisition of Crossflo, and seeking the return of 2,844,630 shares of our common stock held by the Escrow Agent. Subsequently, former shareholders of Crossflo representing a majority of the escrowed shares responded in protest to our claim, delaying the release of the escrowed shares until a formal resolution is reached. In the event we fail to prevail in our claim against the escrowed shares, we may be obligated to deposit into escrow approximately $256,000 of cash consideration due to the decline in our average stock price over the one year escrow period, calculated in accordance with the Section 2.5 of the Agreement. We have evaluated the potential for loss regarding our claim and believe that we will prevail. Accordingly, we have not recorded a contingent liability for this matter.

20. Segment Information

Holocom began operations in February 2007 and we consolidated Holocom in our consolidated financial statements commencing in March 2007. Due to a re-consideration event we deconsolidated Holocom on May 1, 2009 (see Note 14). Holocom was an operating segment as revenue was 10% or more of the total revenue of all operating segments. Segment information regarding Holocom’s operations is presented for June 1, 2008 though April 30, 2009 in the fiscal 2009 column below.

Holocom is engaged in the business of developing and manufacturing network-security hardware for sale to government, military, and other high-security facilities. There was no inter-segment revenue, and the accounting policies for segment reporting were the same as for us as a whole.

We acquired PDSG in a series of transactions in the second, third and fourth quarters of fiscal 2009 (see Note 4) and consolidate our wholly-owned subsidiary PDSG in our consolidated financial statements. PDSG provides data sharing services and products to the public sector. There is no inter-segment revenue and the accounting policies for segment reporting are the same as for us as a whole.

These reportable segments are strategic business units that offer different products and services. They are managed separately because each business requires different technology and marketing strategies.

The “all other” category includes the results for Patriot Scientific Corporation.

Operating segment net revenue, operating loss and income before taxes for each of the years ended May 31 were as follows:

	2010		2009		2008
Net revenue:
Holocom	$	-	$	4,709,491	$	3,649,898
PDSG		567,934		593,451		-

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Members

Phoenix Digital Solutions, LLC

We have audited the accompanying balance sheets of Phoenix Digital Solutions, LLC (the "Company") as of May 31, 2010 and 2009, and the related statements of income, members' equity and cash flows for each of the three years in the period ended May 31, 2010. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above, present fairly, in all material respects, the financial position of Phoenix Digital Solutions, LLC as of May 31, 2010 and 2009, and the results of its operations and its cash flows for each of the three years in the period ended May 31, 2010 in conformity with accounting principles generally accepted in the United States of America.

Notes to Financial Statements

1. Organization and Business

Phoenix Digital Solutions, LLC (the “Company”) is a Delaware limited liability company organized on June 7, 2005. Through a commercialization agreement dated June 7, 2005, the Company holds the rights to certain patents of its members. The Company receives license fees from license agreements entered into between licensees and a member of the Company and distributes license fee proceeds to its members.

Liquidity Risks and Management’s Plans

During the years ended May 31, 2008, 2009 and 2010, the Company has experienced a decline in license revenues. At August 10, 2010, the Company’s cash and cash equivalents balance was $1,177,211. The ability of PDS to continue as a going concern is dependent on its ability to generate or obtain sufficient cash to meet its obligations on a timely basis. The Company will need to generate proceeds from new license agreements or obtain equity or debt financing to fund its planned operating expenses and working capital requirements for the foreseeable future. Currently, the Company has no commitments to obtain additional capital from sources outside of that which may be contributed by the members, and there can be no assurance that financing will be available in amounts or on terms acceptable to the Company, if at all.

Because of the uncertain nature of the negotiations that lead to license revenues, pending litigation with companies which the members believe have infringed on their patent portfolio, the possibility of legislative action regarding patent rights, petitions with the USPTO to re-examine certain of the patents, the possible effect of new judicial interpretations of patent laws, and current litigation between the members of PDS, there is no assurance that the Company will receive any future revenues from license agreements, or if it does, that such license revenues in the future will be consistent with amounts received in the past.

In the event the Company is unable to successfully generate proceeds from license agreements at historical levels or obtain additional capital, it is unlikely that the Company will have sufficient cash flows and liquidity to finance its business operations as currently contemplated. Accordingly, in the event new financing is not obtained, the Company will likely reduce general and administrative expenses, including legal fees, litigation activity and other licensing costs, until it is able to obtain sufficient financing to do so.

2. Summary of Significant Accounting Policies

Limited Liability Company Operating Agreement

As a limited liability company, each member’s liability is limited to the capital invested. Allocation of profits, losses and distributions is in accordance with the terms as defined in the operating agreement.

The Company is treated as a partnership for federal income tax purposes. Consequently, federal income taxes are not payable by the Company. The Company’s net income or loss is allocated among the members in accordance with the operating agreement of the Company and members are taxed individually on their share of the Company’s earnings. The State of California assesses a limited liability company fee based on the Company’s income in addition to a flat limited liability company tax. Accordingly the financial statements reflect a provision for these California taxes.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures. Accordingly, actual results could differ from those estimates.

F-57

Phoenix Digital Solutions, LLC

Notes to Financial Statements (Continued)

Summary of Significant Accounting Policies (continued)

Revenue Recognition

The Company generally recognizes revenue upon receipt of the license proceeds from the licensee at which time all obligations of the Company have been performed under the license agreements (see Note 3).

Cash Equivalents

The Company considers all highly liquid investments with a maturity of three months or less at the date of acquisition to be cash equivalents.

Financial Instruments and Concentrations

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents.

Credit Risk

At May 31, 2010 and 2009, the Company’s cash and cash equivalents balance consisting of money market accounts not subject to FDIC insurance was $779,932 and $1,343,582, respectively. The Company limits its exposure of loss by maintaining its cash with a financially stable financial institution.

Intellectual Property Rights

The Company relies on a combination of patents, trademarks, copyrights, trade secret laws, confidentiality procedures and licensing arrangements to protect its intellectual property rights. The Company currently has seven U.S. patents, one European patent, and one Japanese patent issued. A successful challenge to its ownership of the technology or the proprietary nature of the intellectual property would materially damage the Company’s business prospects. Any issued patent may be challenged and invalidated.

3. Licenses Receivable

The Company generally recognizes revenue upon receipt of the license proceeds from the licensee at which time all obligations of the Company have been performed under the license agreements.

At May 31, 2010, the balance in licenses receivable consists of a license agreement for which partial payment was made in fiscal 2010 and the remaining payment of $2,000,000 was received by the Company during July 2010.

At May 31, 2009, the balance in licenses receivable consists of a license received during May 2009, but deposited to an incorrect bank account and a license agreement signed in April 2009 for which partial payment was made in fiscal 2009 and the remaining payment was received in June and July 2009.

4. Formation and Commercialization Agreement

The Company has two members: Technology Properties Limited Inc. (“TPL”), and Patriot Scientific Corporation (“PTSC”). Each member owns 50% of the membership interests of the Company. Each member has the right to appoint one member of the three member management committee. The two appointees are required to select a mutually acceptable third member of the management committee.

F-58

Phoenix Digital Solutions, LLC

Notes to Financial Statements (Continued)

Formation and Commercialization Agreement (continued)

Pursuant to the LLC Agreement, the members agreed to establish a working capital fund for the Company of $4,000,000, of which each member contributed $2,000,000. The working capital fund increases to a maximum of $8,000,000 as license revenues are achieved. The members are obligated to fund future working capital requirements at the discretion of the management committee of the Company in order to maintain working capital of not more than $8,000,000. Neither member is required to contribute more than $2,000,000 in any fiscal year. During the fiscal year ended May 31, 2010 PTSC and TPL each contributed $580,000 to the Company for working capital requirements. Distributable cash and allocation of profits and losses will be allocated to the members in the priority defined in the LLC Agreement.

On June 7, 2005, the Company entered into a Commercialization Agreement with TPL and PTSC. This Commercialization Agreement allows TPL to commercialize the patent portfolio by entering into settlement and/or license agreements, suing in the name of TPL, PTSC, the Company and Charles Moore, and manage the use of the patent portfolio by third parties.

Under terms of the Commercialization Agreement, the Company is required to pay a quarterly amount ranging between $500,000 and $1,000,000 (based upon a percentage of the working capital fund balance) to TPL for TPL’s supporting efforts to secure licensing agreements for the Company.
