June 25, 2009 7:51 AM EDT

Tessera Technologies, Inc. (Nasdaq: TSRA) provided a status update on certain U.S. Patent and Trademark Office (PTO) actions.

On June 22, 2009, the PTO issued documents in the patent reexamination proceedings involving Tessera's US Patent No. 5,852,326 (the '326 patent), and US Patent No. 6,465,893 (the '893 patent). In the ex parte reexamination proceeding of the '326 patent, the PTO issued an Advisory Action restating and revising the rejections of patent claims subject to reexamination that had been set forth in the previous Final Action. The '326 patent's validity has been upheld in litigation, including in the recently-concluded International Trade Commission (ITC) action, ITC Inv. No. 337-605 (Wireless ITC action) against Motorola, Qualcomm, Freescale and others. In the inter partes reexamination proceeding of the '893 patent, the PTO issued a Right of Appeal Notice restating and revising the prior rejections of the claims under reexamination. Tessera is currently reviewing its options related to both of these proceedings.
