Eastman Chemical Co. (EMN) announced that the United States District Court in Wilmington, Del., has ruled in favor of the company in a patent infringement lawsuit filed by Wellman, Inc.
The court's decision that held two Wellman patents invalid ended the case which was scheduled to go to trial February 17, 2010.
In September 2007, Wellman filed a lawsuit against Eastman in U.S. District Court claiming that Eastman's manufacture of certain ParaStar PET resins infringed two Wellman patents. The ruling confirms that Eastman continues to be free to practice its innovative technology used to make its ParaStar products.
