Gevo, Inc. : Gevo Overcomes 110 Rejections in USPTO Reexamination ENGLEWOOD, Colo. - April 11, 2013 - Gevo, Inc. (NASDAQ: GEVO) announced today that the U.S. Patent and Trade Office (USPTO) issued a second office action in the ongoing inter partes reexamination of Gevo's U.S. Patent No. 8,101,808 ('808 Patent) entitled "Recovery of Higher Alcohols from Dilute Aqueous Solutions", which relates to Gevo's Integrated Fermentation Technology^® (GIFT^®). The Examiner's decision, which dismissed 110 previous grounds of rejection and introduced a limited number of new rejections, is a non-final action called an Action Closing Prosecution (ACP), and gives Gevo the opportunity to respond to the limited new questions raised by the USPTO Examiner. The '808 Patent remains valid and fully enforceable during the reexamination process. "Gevo will respond to the ACP and is confident that the remarks presented in the response will be sufficient to overcome the limited number of new rejections," said Brett Lund, Gevo's executive vice president and general counsel. "Importantly, Gevo was successful in eliminating all of the previous 110 rejections presented in the first office action and the minimal number of new rejections are based on obviousness as opposed to novelty." Gevo continues to maintain full freedom to operate worldwide. This ACP does not impact in any way Gevo's ability to commercialize isobutanol, nor does it impact in any way Gevo's operations at its plant in Luverne, MN. Gevo has an additional issued GIFT^® patent that solidly protects Gevo's isobutanol recovery process in US Patent No. 8,283,505, entitled "Recovery of Higher Alcohols for Dilute Aqueous Solutions", issued October 9, 2012. Furthermore, Gevo has another issued patent broadly covering both Gevo's and Butamax Advanced Biofuels LLC's (Butamax's) intended isobutanol recovery processes in US Patent No. 8,304,588, entitled "Recovery of Higher Alcohols from Dilute Aqueous Solutions", issued November 6, 2012. Gevo is suing Butamax, a 50/50 joint venture between DuPont and BP, for infringing the '808 Patent. This case is scheduled to go to trial in the US District Court of Delaware in July of 2014. About Gevo Gevo is a leading renewable chemicals and next-generation biofuels company.
