1. Assignment of Transferred Assets. Assignor hereby unconditionally and irrevocably sells, assigns, transfers, conveys, and delivers to Assignee, its successors and assigns, all his right, title, and interest in, to, and under the Transferred Assets, said Transferred Assets set forth herein in Exhibit A, and any reissues, reexaminations, renewals, continuations, continuations-in-part, divisions, substitute applications thereof, and the like, and any extensions thereof, and all patents worldwide that may be granted thereon, together with the right to file such applications and the right to claim for the same the priority rights derived from such patent application under the laws of the United States and its territorial possessions, the International Convention for the Protection of Industrial Property, or any other international agreement or the domestic laws of the country in which any such application is filed, as may be applicable, to be held and enjoyed by Assignee for its own use and enjoyment, and for the use and enjoyment of its successors and assigns, to the end of the term or terms for which such patents may be granted or reissued, as fully and entirely as the same would have been held and enjoyed by Assignor if this assignment and sale had not been made.

2. Cooperation with Assignee. Assignor agrees to cooperate with Assignee to provide the necessary executed assignments and other documents as required to perfect the assignment set forth in Section 1. Assignor further covenants that Assignee will, upon its request, be provided promptly with all pertinent facts and documents relating to said inventions and said Letters Patent and legal equivalents as may be known and accessible to Assignor and will testify as to the same in any interference, litigation, or proceeding related thereto and will promptly execute and deliver to Assignee or its legal representatives any and all papers, instruments or affidavits required to apply for, obtain, maintain, issue and enforce said application, said inventions and said Letters Patent and said equivalents thereof which may be necessary or desirable to carry out the purposes thereof.

3. Issuance of Future Patents. Assignor hereby authorizes and requests the Commissioner of Patents and Trademarks of the United States, and any officer of any country or countries foreign to the United States, whose duty it is to issue patents or other evidence or forms of intellectual property protection to issue respective Letters of Patent to Assignee, and the entire right, title, and interest in and to the same, for its sole use and benefit; and for the use and benefit of its successors and assigns, to the full end of the term(s) for which said Patent(s) may be granted, as fully and entirely as the same would have been held by me had this assignment not been made.

4. No Prior Encumbrance. Assignor hereby covenants that no assignment, sale, agreement, or encumbrance has been or will be made or entered into which would conflict with the terms of this Assignment.

5. Right to Sue for Past Infringement. Assignor hereby expressly grants to Assignee all of Assignor’s rights to bring any necessary action, including, but not limited to lawsuits, against any past, present, or future third party infringers, potential or actual, of any Transferred Asset as if the Assignor himself were bringing such action. Assignee shall have the right to any and all recoveries from any such actions and Assignor hereby waives any recovery obtained by Assignee.
