ENGLEWOOD, Colo., Feb. 18, 2014 (GLOBE NEWSWIRE) -- Gevo, Inc. (Nasdaq:GEVO), the world's only commercial producer of renewable isobutanol, announced today that the U.S. Court of Appeals for the Federal Circuit (Appeals Court) issued a decision in a patent case involving Butamax's Patent Nos. 7,851,188 ('188 Patent) and 7,993,889 ('889 Patent). The appeals court offered a new interpretation of a disputed claim term, vacated the district court's prior rulings, and ordered the court to reconsider issues related to infringement and invalidity.
On remand, two issues remain to be determined: 1) whether the patents are valid; and 2) whether Gevo infringes them under the new claim interpretation. The claims of the two Butamax patents at issue are currently under reexamination at the United States Patent and Trademark Office (USPTO), which has declared them unpatentable. Gevo believes that it does not infringe any valid claims, and at this time maintains freedom to produce and sell isobutanol worldwide and into all markets.
Gevo is a leading renewable chemicals and next-generation biofuels company. Gevo's patent-protected, capital-light business model converts existing ethanol plants into bio-refineries to make isobutanol. This versatile chemical can be directly integrated into existing chemical and fuel products to deliver environmental and economic benefits. Gevo has executed initial commercial-scale production runs at its isobutanol facility in Luverne, Minn., constructed in conjunction with ICM, a leading provider of proprietary ethanol process technology, and has a marquee list of partners including The Coca-Cola Company, Sasol Chemical Industries, and LANXESS, Inc., an affiliate of LANXESS Corporation, among others. Gevo is committed to a sustainable bio-based economy that meets society's needs for plentiful food and clean air and water. For more information, visit www.gevo.com.
