Gevo Inc. (GEVO), announced that a judgment of non-infringement will be entered for Gevo following the acknowledgment by Butamax Advanced Biofuels LLC that Gevo does not infringe Butamax's asserted patents under the Court's construction of a key claim term in Butamax's Patent Nos. 7,851,188 and 7,993,889. As a result of this victory, a judgment of non-infringement will be entered in Gevo's favor and the trial scheduled for April 1st will no longer take place.
The company stated that the judgment of non-infringement comes on the heels of the Court's important claim construction determination which held that Butamax's Patent Nos. 7,851,188 and 7,993,889 require the use of an "NADPH-dependent" KARI. Butamax conceded that it could not establish that Gevo's KARI is NADPH-dependent.
In addition to granting a judgment of non-infringement, the Court invalidated Butamax's patent claims for the deletion of PDC. PDC is the enzyme responsible for making ethanol and its deletion is required for the commercially viable production of isobutanol. Gevo's patents covering the deletion of PDC and the use of AFT are set for trial in August of this year, where Gevo is suing Butamax for patent infringement.
