CHANDLER, Ariz., April 4 -- Amkor Technology, Inc. (Nasdaq: AMKR) announced today that on March 31, 2005 the International Trade Commission ordered new claims construction on numerous patent claim terms relating to Amkor's proprietary MicroLeadFrame® package technology. The ITC also remanded the case to the presiding administrative law judge (ALJ) to conduct further proceedings and make new findings necessitated by the Commission's clarification of Amkor's claims.
The Commission originally instituted an investigation of Carsem on December 19, 2003 based on a complaint filed by Amkor alleging patent infringement of U.S. Patents 6,433,277, 6,455,356 and 6,630,728 relating to Quad Flat No-lead (QFN) products. On November 18, 2004 the ALJ issued an Initial Determination finding no violation of section 337 of the Tariff Act. On February 1, 2005 the Commission decided to review the Initial Determination in its entirety. On Thursday, the Commission rendered its decision ordering a new claims construction and remanding the investigation to the ALJ. The subsequent decision by the ALJ will be subject to review by the full Commission, which has targeted November 21, 2005 for completion of the investigation.
"We are pleased that the Commission has provided the ALJ with a definitive clarification as to the meaning of our patent claims and believe that this will have a positive effect on our case against Carsem," said John Boruch, Amkor's President and COO. "We believe that this action by the Commission will strengthen our infringement claims against Carsem, and we are optimistic that the validity of our patents will withstand judicial review. We are hopeful that the Commission's order will result in the ultimate finding of a violation of the Tariff Act and an exclusion order which would prohibit Carsem from importing its infringing QFN products into the U.S."
MicroLeadFrame® is Amkor's proprietary version of an IC package with the generic nomenclature of QFN, which stands for "quad, flat-pack, no lead."
