CHANDLER, Ariz., Nov 19 -- Amkor Technology, Inc. (Nasdaq: AMKR) has filed suit in Federal District Court in the Northern District of California, against Carsem(M) Sdn Bhd, Carsem Semiconductor Sdn Bhd, and Carsem Inc. (collectively "Carsem"). The suit alleges infringement of Amkor's United States Patent Nos. 6,433,277, 6,455,356, and 6,630,728 (collectively the "Amkor Patents"). Amkor alleges that by making, using, selling, offering for sale, or importing into the U.S. of the Carsem Dual and Quad Flat No-Lead Package, the defendants infringe on one or more of the MicroLeadFrame® packaging technology claims in the Amkor Patents. The District Court suit seeks both injunctive relief and monetary damages and is a counterpart legal action to a previously filed lawsuit against Carsem in the International Trade Commission, which seeks to halt importation of infringing products.
