California Court Defers to Outcome of TPL`s Infringement Lawsuit in Texas; Northern California Court Grants TPL`s Motion to Stay Proceedings Pending Outcome of Infringement Proceedings Against Major Japanese Manufacturers in Eastern District of Texas

CUPERTINO, Calif.--(BUSINESS WIRE)--March 17, 2006--The TPL Group, a global intellectual property management company, today announced that the US District Court of Northern California has stayed the declaratory judgment actions recently filed in that court against the TPL Group, Patriot Scientific, et al, by major Japanese manufacturers pending outcome of TPL`s earlier-filed action against those same companies in the US District Court in the Eastern District of Texas. This clears the way for the Texas court, sometimes referred to as the `` rocket docket`` for its expeditious rulings in patent infringement cases, to now take the lead in judging TPL`s broad-based intellectual property claims for infringement of three of the ten patents in the Moore Microprocessor Patent(TM) (MMP) Portfolio.

`` This ruling puts a halt to procedural maneuvering by the Matsushita, Panasonic, JVC, Toshiba, and NEC entities,`` said Dan Leckrone, chairman of the TPL Group. Mr. Leckrone noted that the Fujitsu entities, who were also defendants in the Texas action, have recently purchased a license under the MMP Portfolio, and have been dismissed from the Texas and California actions.

The validity of TPL`s views regarding the scope of the MMP Portfolio has gained substantial momentum since marquee chip makers Intel and AMD purchased MMP licenses last year. Since the beginning of 2006, Hewlett-Packard, Casio Computer and Fujitsu have purchased MMP system licenses. TPL believes that the intellectual property protected by the MMP Portfolio is used in a wide variety of end-user products including personal computers, servers, workstations, home theater systems, digital TVs, video games, DVD Recorders/Players, mobile handsets and automotive electronics.

About the MMP Portfolio

Named after legendary inventor Charles `` Chuck`` Moore, the Moore Microprocessor Patent(TM) Portfolio encompasses seven US patents as well as their European and Japanese counterparts. Protected through year of 2015, the MMP portfolio contains intellectual property that became jointly owned by the privately held TPL Group and publicly held Patriot Scientific in a settlement between them in June 2005. Both TPL and Patriot assert that their jointly owned patents have long been essential to the design of microprocessors, microcontrollers, Digital Signal Processor (DSPs), embedded processors and System-on-Chip (SoC) devices. The MMP Portfolio is exclusively managed by Alliacense, a TPL Group enterprise. For more information on the MMP Portfolio, visit www.alliacense.com.
