Santa Ana, CA – Trademark lawyers for E.I. Du Pont De Nemours filed a trademark infringement and Lanham Act unfair competition (15 U.S.C. 1125) lawsuit at the Federal District Court in Santa Ana to protect its TEFLON® trademark. The complaint recites the history of DuPont’s discovery of polytetrafluoroethylene (“PTFE”), which is the slippery, chemically inert compound that is used in a wide variety of different products. Since approximately 1944, DuPont adopted the fanciful trademark “Teflon” for its PTFE products and began to sell products under the trademark and also licensed the trademark for others to use. DuPont owns several USPTO trademark registrations for the TEFLON® trademark in several International Classes of goods. All of the registrations are incontenstable under 15 U.S.C. § 1065.
