Tessera Receives Third Office Action in '627 Patent Reexamination

SAN JOSE, Calif.--(BUSINESS WIRE)--Sept. 15, 2008--Tessera Technologies, Inc. (Nasdaq:TSRA), a provider of transformational technologies that enable innovation in next-generation electronics, today announced the U.S. Patent and Trademark Office (PTO) on Sept. 11, 2008 issued a third non-final office action in the ongoing ex parte reexamination of Tessera's U.S. Patent No. 6,133,627 (the '627 patent). The patent relates to semiconductor packaging technologies used in a variety of applications.

The latest office action, which rejects certain claims of the '627 patent, was issued only one month after the second office action, in which the PTO incorrectly stated that Tessera had "filed no arguments" addressing the prior rejections. After Tessera resubmitted its previously filed response, the PTO issued this third office action, allowing Tessera to file a response by Oct. 13, 2008.

After consideration of Tessera's submission in response to the third office action, the PTO may issue another office action, which may or may not be a final rejection of the claims in question. There is no deadline for further action by the PTO. If a final rejection is issued, Tessera will have the opportunity to submit a response to the PTO for its consideration, after which the PTO may either reopen the reexamination of the patent or allow Tessera to file a Notice of Appeal with the Board of Patent Appeals and Interferences.

The claims of a patent undergoing reexamination are valid until a reexamination certificate cancelling the claims is issued. A certificate can only be issued after all actions closing prosecution are concluded, and all appeals have been exhausted.

Tessera is asserting the '627 patent in a number of litigations including an investigation pending in the U.S. International Trade Commission (ITC) against several companies. A hearing in that investigation is scheduled to begin on Sept. 22, 2008.
