TULSA, Okla., July 3, 2013 (GLOBE NEWSWIRE) -- On June 26, 2013, the U.S. Patent & Trademark Office ("PTO") issued an Office Action Closing Prosecution and rejecting all claims in the ongoing inter partes reexamination of Neste Oil's U.S. Patent No. 8,187,344. The reexamination was initiated by Syntroleum Corporation (Nasdaq:SYNM) in August of 2012 after Neste filed suit against Syntroleum on May 29, 2012 in federal court in the District of Delaware. On January 31, 2013, the District Court stayed the lawsuit pending the final outcome of the PTO's reexamination of the '344 patent. Mirroring its prior office action (dated September 14, 2012), the PTO has again rejected both the original claims of the '344 patent, as well as the amended and new claims submitted by Neste, as obvious in view of the prior art. The reexamination proceedings remain pending at the PTO under Reexam Control Number 95/002,084.
