Gevo Denies All Claims of Infringement in the Butamax Patent Infringement Complaint

ENGLEWOOD, Colo., Mar 25, 2011 (BUSINESS WIRE) -- Gevo, Inc. (NASDAQ: GEVO), a renewable chemicals and advanced biofuels company, today filed its answer in Delaware District Court to the patent infringement complaint filed on January 14, 2011 by Butamax Advanced Biofuels LLC, which alleges that Gevo is infringing one patent that has been assigned to Butamax relating to the production of isobutanol.

"Our answer, filed in Delaware district court, formally denies all claims of infringement, as we use Gevo's Integrated Fermentation Technology(R) (GIFT(R)), which is covered by over 150 patent applications, and is a different approach than the one described in the Butamax patent," said Brett Lund, Gevo Executive Vice President and General Counsel. "We will vigorously defend against the claims asserted in the complaint."
