Durham LED giant Cree is on the offensive, filing federal complaints that a competing firm, California-based Feit Electric Company, infringed on 10 of its patents. In papers filed with both the U.S. International Trade Commission and the U.S. District Court for the Western District of Wisconsin against Feit and its Asian supplier, Unity Opto Technology Co., Cree requests that the ITC issue an order to exclude "infringing and falsely advertised articles" from entering the United States.
