Neste contends Dynamic Fuels LLC, a joint venture between Springdale, Arkansas-based Tyson and Tulsa, Oklahoma-based Syntroleum Corp., is making a product that violates a new patent for NExBTL diesel fuel.
“Defendants have no license or other authorization to use the inventions” and owe damages, Neste said in a complaint filed yesterday in federal court in Wilmington, Delaware. The Espoo, Finland-based company has invested 1.5 billion euros ($1.86 billion) in diesel production, according to a statement.
Amanda Burns, a spokeswoman for Syntroleum, wasn’t immediately available to respond to a phone call and e-mail seeking comment on the lawsuit. Gary Mickelson, a spokesman for Tyson, wasn’t immediately able to comment.
The case is Neste Oil Oyj (NES1V) v. Dynamic Fuels LLC, 12-cv-662, U.S. District Court, District of Delaware (Wilmington).
