E.I. du Pont de Nemours & Co. v. Cetus Corporation
In 1989, American chemical company, E.I. du Pont de Nemours & Co., filed suit against
Cetus Corporation, alleging the Cetus core PCR patents were not novel. Despite strong
witnesses, DuPont could not prove that PCR invention had been obvious, and court ruled
in favor of Cetus.
