ENGLEWOOD, Colo., Nov 28, 2011 (BUSINESS WIRE) -- Gevo, Inc. /quotes/zigman/3670856/quotes/nls/gevo GEVO +3.22% , a leading renewable chemicals and advanced biofuels company, today announced that the United States Patent and Trademark Office (USPTO) has agreed to reexamine U.S. Patent No. 7,993,889 ('889 Patent) owned by Butamax(TM) Biofuels LLC (Butamax), determining that substantial questions of patentability exist. In addition to granting the reexamination, the USPTO issued an office action finding that all challenged claims are invalid. The USPTO agreed with Gevo's petition that substantial questions exist regarding whether others invented this technology first and that several scientific journal publications had described the technology before Butamax applied for the patent.
"This USPTO action means that key claims contained in the formerly granted patent are now invalid effective immediately and are subject to a complete inter party examination," said Brett Lund, Gevo Executive Vice President and General Counsel. "The USPTO action raises serious questions regarding the merits of Butamax's claims against Gevo and strengthens our position in the pending infringement lawsuit."
Gevo's patent portfolio consists of over 300 patents and applications for the economic production of isobutanol, process innovations and downstream product applications.
