Tessera Technologies, Inc. announced today that a California state appellate court affirmed a lower court ruling denying a petition by Amkor Technology, Inc. to correct an arbitration award that the International Court of Arbitration of the International Chamber of Commerce issued in July 2012 in favor of Tessera, Inc. in its contract dispute with Amkor. This award was the basis for the arbitrators' ultimate damages award that a California trial court recently confirmed in the amount of $128.3 million plus ongoing post-judgment interest in Tessera's favor.
