Item 8.01 Other Events.

On September 10, 2013, Neste Oil Oyj filed a Petition for Inter Partes Review ("IPR") of Syntroleum Corporation’s U.S. Patent No. 8,231,804 (the ‘804 patent) in the U.S. Patent and Trademark Office. The ‘804 patent is directed to an even carbon number paraffin composition and method of manufacturing same. The IPR procedure allows a party to challenge the validity of a patent in whole or in part before the Patent Trials and Appeals Board (PTAB) via a patent validity trial. However, such a validity trial will only commence if the PTAB decides to institute the IPR proceeding, after first considering the challenger’s Petition and any Preliminary Response made by the Patent Owner (i.e., Syntroleum). Should the PTAB determine that Neste’s Petition meets the minimal formal filing requirements, Syntroleum will be given 3 months to file an optional Preliminary Response. Upon receipt of any Preliminary Response, the PTAB has another three months in which to institute or deny the IPR proceeding. A U.S. patent is presumed valid unless and until the PTAB (or court) makes an invalidity determination. Syntroleum intends to defend the validity of the ’804 patent.
