Wellman, Inc. announces the initiation of a patent infringement lawsuit against Eastman Chemical Company for infringement of United States Patent Nos. 7,129,317 and 7,094,863 owned by Wellman that cover titanium catalyzed polyethylene terephthalate (“PET”) resins and the preforms made from titanium catalyzed PET resins. The complaint alleges that Eastman infringes Wellman’s ‘317 patent with its ParaStar resins that are made from its IntegRex process and Eastman is inducing third parties, including its customers, to infringe Wellman’s ‘863 patent when they make preforms using ParaStar resin.
