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.

Gevo Challenges Validity of Butamax Patent Over Biofuels

Gevo Inc. said the U.S. Patent and Trademark Office is reconsidering a patent that the agency issued in August to Butamax Advanced Biofuels LLC for a fuel additive. The PTO upheld another patent as final

In a non-final action dated Nov. 25, the PTO said the patent claims were invalid, according to the agency’s website. Butamax will have a chance to respond to the agency’s findings, and by law the patent remains valid and enforceable during the review process.

Gevo, based in Englewood, Colorado, said in a statement it sought the review, adding 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.”

Butamax, based in Wilmington, Delaware, is a joint venture of BP Plc (BP/) and DuPont Co., according to information on its website and has brought patent litigation against Gevo. CEO Paul Beckwith said, in a statement on its website, that “We are pleased that the U.S. Patent Office found Gevo’s attempts to invalidate our first patent to be without merit and we are confident that our second patent, which is a continuation of the first, will ultimately receive the same revalidation.”
