TESSERA RECEIVES SECOND OFFICE ACTION IN ‘326 PATENT REEXAMINATION

Tessera Technologies, Inc. (Nasdaq:TSRA), a leading provider of miniaturization technologies for the electronics industry, today announced the U.S. Patent and Trademark Office (PTO) on August 1, 2008 issued a second office action in the ongoing ex parte reexamination of Tessera's U.S. Patent No. 5,852,326 (the '326 patent). The patent relates to semiconductor packaging technologies used in a variety of applications. After receipt of the document, Tessera will have an opportunity to respond to the examiners’ decision, which rejects certain claims of the '326 patent. The initial office action on this patent was received on February 21, 2008.

After considerations of Tessera’s submission in response to the second office action, the examiners will 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 examiners. If a final rejection is issued by the examiners, Tessera will have the opportunity to submit a response to the examiners for their consideration, after which the examiners may either reopen the prosecution 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 ‘326 patent in two investigations pending in the U.S. International Trade Commission (ITC) against a number of companies. The first of those actions was completed on July 18, 2008. The second action is scheduled for a 7-day hearing to begin on February 5, 2009.
