HOUSTON (ICIS)--Butamax Advanced Biofuels has filed a patent infringement lawsuit in the US against renewable fuels firm Gevo, officials said on Thursday.

Butamax, a joint venture between DuPont and BP, alleges in the case court brought in a US District Court in Delaware that Gevo infringed one of its newly issued patents “which describes Butamax’s foundational methods for low-cost production of biobutanol”.

In a statement, Gevo said it believes Butamax’s case to be “without merit”.

“We are the leaders in the technology and commercialisation of low-cost isobutanol,” said Gevo CEO Pat Gruber. “Unfortunately, lawsuits like this are typical disputes that leaders face.”

Christine Lhulier, vice-president and general counsel of Butamax, said: “We pioneered fermentative production of isobutanol and violation of our intellectual property rights is unacceptable.”

Gevo is retrofitting existing ethanol plants into biorefineries to make renewable building block products for the chemical and fuel industries. The company plans to convert renewable raw materials into isobutanol and renewable hydrocarbons.

Germany-based chemicals major LANXESS is a stakeholder in Gevo.

DuPont and BP formed Butamax in 2009 to develop and commercialise biobutanol as a next-generation renewable biofuel for the transport market.
