Patriot Scientific To Now Focus On Outcome of Infringement Lawsuit in Texas

--Patriot Scientific Corporation (OTC Bulletin Board: PTSC - News), an intellectual property licensing company, today announced that the U.S. District Court of Northern California has stayed the declaratory judgment actions recently filed in that court against the TPL Group, a global intellectual property management company, and Patriot Scientific, et al, by major Japanese manufacturers. Further proceedings in the California actions were stayed pending outcome of TPL's earlier-filed action against those same companies in the U.S. 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 10 patents in the Moore Microprocessor Patent(TM) (MMP) Portfolio that is jointly owned by the TPL Group and Patriot Scientific.

"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. 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.

"The TPL Group continues to have our complete confidence as they proceed with their highly effective, exclusive management of our valuable jointly owned patent portfolio," stated David Pohl, chairman and CEO of Patriot Scientific.
