On July 26, 2013, Judge Robinson of the U.S. District Court for the District of Delaware granted a motion by Butamax Advanced Biofuels, LLC (Butamax) for summary judgment of non-infringement of U.S. Patent No. 8,017,375 (the '375 Patent) and U.S. Patent No. 8,017,376 (the '376 Patent), granted in part and denied in part Butamax's motion for summary judgment of invalidity of the '375 Patent and the '376 Patent, denied a motion by Gevo for summary judgment of validity of the '376 Patent, and denied Butamax's motion to exclude expert testimony on the '376 Patent. This court ruling is not material to the business of the company and is not material to any of the company's other pending litigation cases with Butamax.
On May 10, 2013, Gevo, announced that it had agreed to temporarily dismiss its lawsuit against Butamax and E. I. du Pont de Nemours and Company (DuPont) for infringing one of Gevo's three GIFT ® patents, U.S. Patent No. 8,101,808 (the '808 Patent). Gevo maintains all of its other lawsuits against Butamax and DuPont for infringing Gevo's biocatalyst technology. The company decided to dismiss the '808 Patent lawsuit, for now, in part because Butamax doesn't have a commercial plant that infringes the '808 Patent and, according to DuPont, they will not have a commercial plant by the time of the trial.
Revenues for the second quarter of 2013 were $1.9 million compared to $7.0 million in the same period in 2012. During the second quarter of 2013, the company focused on activities that culminated in the resumption of startup isobutanol production announced in June 2013. The decrease in revenues resulted from the company ceasing ethanol production at its Luverne facility in May 2012. Revenue reported in the second quarter of 2013 included proceeds of $0.9 million from further reduction of Gevo's corn inventory, sales of biobased jet fuel to the U.S. Air Force (USAF) of $0.3 million, revenue under its agreement with The Coca-Cola Company, and revenue from ongoing research agreements. Revenue in the second quarter of 2012 primarily related to the sale of ethanol and related products.
