Patriot Scientific Announces Nokia Purchase of Moore Microprocessor Patent Portfolio License

CARLSBAD, Calif. - May 4, 2007 -- Patriot Scientific Corporation (OTC Bulletin Board: PTSC) confirmed today that Nokia, a world leader in mobile communications, has purchased a Moore Microprocessor Patent™ (MMP) Portfolio license. Patriot Scientific and The TPL Group are co-owners of the MMP Portfolio, which Alliacense, a TPL Group enterprise, exclusively manages.

"The feature richness of mobile phones would not be possible without exploiting the design techniques engendered by the MMP Portfolio," said Mike Davis, Alliacense Senior VP of Licensing. "Such techniques are fundamental in the design of microprocessors and enable higher performance and lower cost in a host of digital products ranging from mobile phones and portable music players to communications infrastructure and medical equipment to automobiles, which today deploy dozens of microprocessors."

Nokia is the 17th company to join the distinguished roster of global manufacturers that have captured early-mover MMP licensing berths in specific industry segments since January 2006. Alliacense again confirmed that subsequent licensees in segments where early tiers have been secured are subject to progressively higher royalty rates on relevant products.

"As co-owner of the MMP Portfolio we are pleased to welcome Nokia as the newest addition to the growing list of global companies participating in the MMP Portfolio Licensing Program," said David Pohl, chairman and CEO of Patriot Scientific Corporation. He noted that HP, Casio, Fujitsu, Sony, Nikon, Seiko Epson, Pentax, Olympus, Kenwood, Agilent, Lexmark, Schneider Electric, NEC Corporation, Funai Electric, SanDisk and Sharp Corporation have purchased MMP Portfolio licenses. Intel and AMD are also licensees.

Pohl noted that the strong momentum of the licensing program validates the decision by Patriot's board of directors in June 2005 to shift the company's primary business model from manufacturing and marketing products to a model currently focused primarily but not exclusively on licensing their joint venture MMP patent portfolio. He emphasized that Patriot Scientific invested millions of dollars and hundreds of thousands of man-hours over 12 years or more developing and bringing to market products based upon the company's intellectual property, including IP contained in the MMP Portfolio.

"As evidenced by information in our recent quarterly report and presented at our annual meeting of shareholders last week, we are continuing to seek and evaluate opportunities to diversify our revenue stream by developing and marketing new technologies, entering into joint ventures or by acquiring other companies and technologies," Pohl stated. "We are always focused on the goal of increasing the financial position and strength of the company and providing value to our shareholders."
