HOUSTON (ICIS)--Butamax Advanced Biofuels said on Tuesday that a lawsuit accusing it of patent infringement in the making of bio-based isobutanol was baseless.
Earlier on Tuesday, Gevo said it had filed a lawsuit against Butamax for alleged infringement of Gevo’s two newly issued isobutanol patents. “Gevo’s lawsuit against Butamax is baseless and irresponsible” said Paul Beckwith, CEO of Butamax, which is a joint venture by US DuPont and UK-based energy major BP.
“When Butamax makes isobutanol, we do not use the technology claimed in the Gevo patents,” Beckwith said.
“We are so confident about this, that we offered Gevo an opportunity to independently verify that Butamax does not infringe either of these patents,” Beckwith continued. “Ignoring both our offer to verify and the facts, Gevo instead filed its lawsuit.”
Butamax maintained that the Gevo patents were in fact based on Butamax’s technology.
Butamax filed a patent infringement lawsuit in August against Gevo.
