Amkor Announces Rulings In License Agreement-Related Dispute With Tessera

(RTTNews) - Amkor Technology Inc (AMKR) Sunday announced two rulings in its long-running dispute with Tessera Technologies Inc related to a license agreement entered into in 1996 between Tessera and Amkor's predecessor.

On October 10, 2014, the Patent Trial and Appeal Board at the United States Patent and Trademark Office, in an inter partes review proceeding, or IPR, ruled on Amkor's petition seeking cancellation of certain claims of U.S. Patent No. 6,046,076. In a two-one decision, the IPR board reversed its preliminary determination and denied Amkor's petition with respect to the most material claims.

As previously reported, an arbitration panel has awarded Tessera royalties of $113 million plus interest, most of which relate to our alleged use of the '076 patent. The Superior Court for San Francisco County formally confirmed the arbitration panel's award on October 9.

"We believe the decisions by the IPR board and Superior Court are in error and plan to pursue all avenues of appeal," noted Gil Tily, Amkor's executive vice president and general counsel.

Other proceedings with respect to the arbitration award in the California state appellate court and the United States District Court for the District of Delaware remain pending.
