Patriot Scientific Announces Purchase by NEC of First 2007 Moore Microprocessor Patent(TM) Portfolio License

CARLSBAD, Calif. -- Feb. 8, 2007 -- Patriot Scientific Corporation (OTC Bulletin Board: PTSC) confirmed today that NEC Corporation has purchased a Moore Microprocessor Patent(TM) (MMP) Portfolio license. As the first global manufacturer to become an MMP Portfolio licensee in 2007, NEC closely follows in the footsteps of HP, Casio, Fujitsu, Sony, Nikon, Seiko Epson, Pentax, Olympus, Kenwood, Agilent, Lexmark and Schneider Electric, all 12 of whom purchased MMP licenses during 2006.

Patriot Scientific and The TPL Group are co-owners of the MMP Portfolio, which Alliacense, a TPL Group enterprise, exclusively manages. MMP Portfolio patents encompass fundamental design techniques that enable higher performance and lower cost digital electronic systems ranging from cell phones and portable music players to communications infrastructure and medical equipment as well as automobiles, which today utilize dozens of microprocessors.

"After several years of exhaustive study and negotiation, we are pleased with NEC's decision to purchase an MMP Portfolio license," said Mac Leckrone, Alliacense president. "NEC becomes our inaugural MMP Portfolio licensee in 2007, as well as the first to capture a berth in the networking and communications industry segment." He noted that the MMP Portfolio licensees in this segment, as well as future licensees in segments where early tiers have been captured, are subject to progressively higher royalty rates. "We are especially pleased that NEC has chosen to become TPL's program partner instead of continuing as a defendant with Matsushita and Toshiba, against whom TPL filed broad-based infringement claims about 15 months ago in the U.S. District Court, Eastern District of Texas."

"As a co-owner of the MMP Portfolio and co-plaintiff with TPL in the litigation still pending in Texas as to infringement claims against defendants Matsushita and Toshiba, we are equally pleased with this decision by NEC," said David Pohl, chairman and CEO of Patriot Scientific Corporation. He noted 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. "Patriot's board of directors decided in June, 2005 to shift our primary business model from manufacturing and marketing products to a model currently focused on licensing our joint venture patent portfolio," Pohl continued. "Each new licensee, with NEC being a significant example, validates that decision."

"We will continue 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, "always pointed toward the goal of increasing the financial position and strength of the company and providing value to our shareholders."
