(Source: Business Wire)Amkor Technology, Inc. (NASDAQ: AMKR) today announced that the Administrative Law Judge ("ALJ") in Amkor's patent infringement case against Carsem in the International Trade Commission has reaffirmed his prior ruling that the Carsem Dual and Quad Flat No-Lead Packages infringe some of Amkor's patent claims relating to MicroLeadFrame® (MLF) technology, that all of Amkor's asserted patent claims are valid, and that Carsem violated Section 337 of the Tariff Act.

"We are pleased that the ALJ has again validated Amkor's technology and patent rights for our MLF packaging solutions," said Ken Joyce, Amkor's President and Chief Executive Officer. "We will now be taking steps under ITC procedures for a ruling by the Commission upholding or adopting the ALJ's decision and issuing an exclusion order that would prohibit Carsem from importing its infringing QFN products into the United States."
