DuPont recently filed a lawsuit claiming INVISTA is infringing a DuPont patent and has misappropriated DuPont trade secrets and proprietary information relating to DuPont's nylon engineering resins business. The suit was filed in U.S. Federal Court in the Southern District of New York. INVISTA is headquartered in US and runs integrated fibers and polymers businesses with a global presence.
DuPont is seeking a permanent injunction, declaratory relief and damages relating to the INVISTA production of nylon 6,6 engineering resins. DuPont claims INVISTA misappropriated DuPont trade secrets, infringed on the company's patents and breached a Patent and Technical Information Agreement. Under the terms of this agreement, INVISTA is not allowed to use DuPont technology to make nylon 6,6 engineering resins for several years.
