Butamax and Gevo Grapple With Biofuels Patent Case Claims
Gevo “has agreed to temporarily dismiss its lawsuit” because Butamax at the present time doesn’t have a chemical plant in which to infringe, according to a statement from Gevo Executive Vice President Brett Lund.
Claims in the patent suit were dismissed and Gevo can’t refile the complaint against Butamax “until a final certificate of reexamination is issued” by the U.S. Patent and Trademark Office, wrote U.S. District Judge Sue L. Robinson in an order May 6 in Wilmington.
At least 13 patent cases have been filed by Butamax and Gevo against each other since 2011, according to court electronic records.
The case is Gevo v. Butamax, 12-cv-00070, U.S. District Court, District of Delaware (Wilmington).
