PTO Issues Initial Office Action on Tessera (TSRA) Patent

March 4, 2008 1:07 PM EST

Tessera Technologies, Inc. (Nasdaq: TSRA), a leading provider of miniaturization technologies for the electronics industry, announced that the U.S. Patent and Trademark Office (PTO) has issued an initial office action regarding Tessera's 6,133,627 patent ("627") in ex parte reexamination. This initial action is non-final and will be subject to a lengthy review process, including the possibility of appeal. This issued patent is presumed to be valid, intact and enforceable during the reexamination process, which on average takes 24 months to complete, not including appeals.

"An initial, non-final office action in an ex parte reexamination is not a final decision and should not be characterized as such," said Bruce McWilliams, chairman, president and chief executive officer, Tessera. "We are one year into the process and just received the first office action on the '627 patent. We believe in the strength and validity of our battle-tested patents and will continue to vigorously defend them."

It is not unusual for the PTO to preliminarily reject claims during the reexamination process. Tessera has the right to argue, and will continue to argue, the merits of its position.

Tessera is concurrently reiterating its revenue guidance for the first and second quarters of 2008, as contained in its announcement dated January 31, 2008. In accordance with company's policy, Tessera's quarterly guidance does not include settlements from the company's current enforcement actions.
