LIVERMORE, CA — January 07, 2005 — FormFactor, Inc. (Nasdaq: FORM) today announced the Korean Intellectual Property Office has dismissed challenges against three issued FormFactor Korea Patents. In dismissing the patent validity challenges, the Korean Intellectual Property Office upheld the validity of all the claims of FormFactor’s Korea Patent Nos. 278342, 399210 and 324064.

The validity challenges were brought by Phicom Corporation, a Korean corporation, after FormFactor filed complaints in the Seoul (South Korea) Southern District Court alleging Phicom’s infringement of four different FormFactor Korean patents. Phicom has appealed the Korean Intellectual Property Office decisions. The Office has not yet conducted a substantive hearing on the fourth FormFactor patent challenged by Phicom.

“The rulings upholding the validity of all three FormFactor Korean patents are an important step for FormFactor as we seek to enforce intellectual property rights embodied in our proprietary technology,” said Igor Khandros, chief executive officer of FormFactor. “The decisions issued by the Korean Intellectual Property Office provide strong support for our pending lawsuits, and confirm the strength of our growing global patent portfolio.”

More information about the Korean Intellectual Property Office rulings will be made available if the decisions are formally published by that Office. The Seoul Southern District Court is expected to conduct substantive hearings on FormFactor’s infringement claims in the next several months.
