Gevo to Appeal US Patent Office ruling following setback on separation, recovery patents

September 28, 2014 |

In Colorado, Gevo announced that the United States Patent and Trademark Office (“USPTO”) issued an inter partes review decision rejecting the claims of Gevo’s U.S. Patent Nos. 8,283,505 (the ‘505 Patent) and 8,304,588 (the ‘588 Patent), which cover methods of isobutanol separation and recovery in retrofit ethanol plants. Gevo plans to appeal the decision to the United States Court of Appeals for the Federal Circuit (the Federal Circuit).

Gevo adds: “The ‘505 and ‘588 Patents remain valid and fully enforceable during the appeal process, and Gevo continues to maintain full freedom to operate worldwide. This decision 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. In addition, this decision only affects two of Gevo’s nearly 500 patents and applications worldwide.”
