Patriot Scientific Confirms Addition of Agilent Technologies to Steadily Expanding Roster of MMP Patent Portfolio Licensees

Growth Strategy Continues As 10th Major Manufacturer Purchases Moore Microprocessor Patent™ Portfolio License During 2006

Carlsbad, CA, November 28, 2006 -- Patriot Scientific Corporation (OTC Bulletin Board: PTSC) confirmed today that Agilent Technologies has become the 10th major manufacturer to purchase a license to use the Moore Microprocessor Patent™ (MMP) Portfolio this year. Patriot Scientific and The TPL Group are co-owners of the MMP Portfolio, which Alliacense™, a TPL Group enterprise, exclusively manages. In addition to Agilent Technologies, license agreements have been signed in 2006 with HP, Casio, Fujitsu, Sony, Nikon, Seiko Epson, Pentax, Olympus and Kenwood. Earlier agreements were signed with AMD and Intel.

"The sound growth strategy for Patriot Scientific continues to move forward with the signing of each license agreement," said David Pohl, Patriot Scientific chairman and CEO. "Our strategy is two-fold. While the Alliacense team is actively engaging in communications with manufacturers who are candidates to become licensees of our patented technology, the management and board of Patriot Scientific are actively evaluating opportunities to create or acquire other revenue sources that would be in addition to what the company is realizing from our valuable patent portfolio."

Pohl noted that preliminary discussions are currently being held with several companies that are candidates for Patriot Scientific to possibly either acquire the companies or their technologies, or to enter into joint ventures related to existing or new technologies.

"The global technology leaders that have purchased MMP Portfolio licenses this year recognize the competitive edge to be gained by licensing MMP technologies sooner rather than later," said Alliacense Sr. Vice President, Licensing Mike Davis. "As we welcome Agilent Technologies to our distinguished roster of MMP licensees, we also want to encourage all electronic product manufacturers to contact us regarding the significant competitive advantages of becoming an early MMP Portfolio licensee."

According to Davis, Agilent Technologies has captured one of the "first-mover" MMP Portfolio licensing berths, which encompass electronic measurement, bio-analytical measurement and semiconductor test solutions products. Agilent Technologies is the world's premier measurement company providing core analytical and electrical instruments to the life sciences, chemical analysis, communications and electronics industries. The company has two primary businesses: bio-analytical measurement and electronic measurement. The company currently has approximately 20,000 employees and serves customers in more than 110 countries. Agilent had revenue of $5.1 billion in fiscal year 2005.

The MMP Portfolio patents, filed in the 1980s, cover techniques that enable higher performance and lower cost designs, and are fundamental to consumer and commercial digital systems ranging from DVD players, cell phones and portable music players to communications infrastructure, medical equipment and automobiles, which today have dozens of microprocessor-based key features and benefits.
