WILMINGTON, Del., July 31, 2012 /PRNewswire/ -- Butamax™ Advanced Biofuels, LLC, the biobutanol technology leader, commented on the lawsuit filed by Gevo today alleging patent infringement of Gevo patent number 8,232,089.

"The Gevo '089 patent adds no new point of novelty over previous Butamax discoveries. As such, Butamax is the rightful owner and innovator of this technology," said Paul Beckwith, Butamax CEO. "We look forward to putting forth detailed evidence both to the court in response to this lawsuit and with the USPTO through its reexamination process."

In a like case, the USPTO recently granted Butamax's request for reexamination of Gevo patent number 8,101,808 rejecting all 156 claims of the patent.  In that case, certain claims were rejected in view of prior Butamax inventions. Given that the Butamax inventions have been accorded significant priority over the Gevo applications, we anticipate a similar result for the '089 patent.
