W.L. Gore wants the U.S. Supreme Court to hear an appeal of its $186 million loss to C.R. Bard in a patent infringement spat over a vascular graft patent.
Gore alleges that 1 of its engineers, Peter Cooper, invented a key claim in the patent in the early 1970s, according to a petition for a writ of certiori filed with the high court.
The U.S. Court of Appeals for the Federal Circuit affirmed in June  that the patent was invented by Dr. David Goldfarb, who later assigned it to Bard. Gore wants the Supremes to rule that the patent was the joint invention of Cooper and Goldfarb, according to court documents.
