Company’s underlying merits action for infringement of Korea patent previously held valid by appellate Patent Court is allowed to proceed forward

LIVERMORE, Calif. – February 12, 2006 – FormFactor, Inc. (Nasdaq: FORM) announced the Seoul Central District Court issued a ruling denying its request for a preliminary injunction for infringement of Korea Patent No. 252457 filed in mid-2006 against Phicom Corporation, a Korean company. The district court ruling does not preclude FormFactor from proceeding on the related patent infringement merits action it has been pursuing at the same time before the court. The company is reviewing the written decision and evaluating the substantive merits of an appeal.

“Our commitment to innovation allows us to develop and deliver wafer test products and solutions that reduce our customers’ overall cost of test and meet their technical roadmaps,” said Igor Khandros, CEO of FormFactor. “We will continue our efforts to protect the investments we make in innovation, which are important not only to FormFactor, but to our customers’ businesses. IP protection is an ongoing, long-term project for FormFactor; there are several infringement actions continuing in Korea and the US litigation is proceeding as planned. ”

The company will continue to assert its infringement claims and support the validity of its Korea Patent No. 252457 before the district court during the course of the full patent infringement merits action, during which a more in-depth review of the claims and defenses is conducted. FormFactor does not believe this latest Korea district court ruling will have any current business impact.
