Gevo, a maker of biofuels, sued DuPont and its business partner Butamax Advanced Biofuels in federal court in Delaware, alleging infringement of a new patent for alcohol-fermentation processes.
The disputed patent issued Monday to Douglas County-based Gevo covers methods for alcohol recovery at reduced cost, according to its written description.
Gevo contends Butamax — a joint venture between DuPont and BP — performed the methods described in the patent without Gevo’s authorization and should pay unspecified damages after a jury trial.
