Patriot Scientific Rejects Offer for Microprocessor Patent Portfolio

SAN DIEGO, Calif., Nov. 11, 2004 -- Patriot Scientific Corporation (OTC Bulletin Board: PTSC) said today that the company has declined an offer from Relational Advisors LLC (http://www.relationalgroup.com) for the sale of its critical microprocessor patents that are believed to be in widespread industry use.

Relational Advisors told the company that it represents Technology Properties Limited (TPL), Daniel Leckrone and Charles Moore in their effort to obtain PTSC ownership of patents US5809336, 6598148, 5440749, 5604915, 5530890, 5784584 and 5659703. PTSC's management and board deemed the $7.5 million dollar offer and related royalty-sharing scheme inadequate for the intellectual property held by PTSC. The company estimates the value to exceed $1 billion.

Relational Advisors, an investment fund with $3 billon under management, continues to pursue avenues to obtain the microprocessor technology held by PTSC. PTSC is the plaintiff in a lawsuit against TPL, Daniel Leckrone and Charles Moore that involves the patents and is expected to go to trial in early 2005.

PTSC is in receipt of a demand letter from NuVen Ltd., an affiliate company of TPL and a recent PTSC shareholder, to provide investment agreements, shareholder agreements, shareholder lists, board minutes and other documents. NuVen is represented by the law firm of Gibson, Dunn & Crutcher LLP of Palo Alto.

Patriot Scientific President and CEO Jeff Wallin said, "The recent activities of Relational Advisors and NuVen serve to validate the significant value of the PTSC patent portfolio. We are making every effort to realize the true value of our intellectual property for the benefit of all of our shareholders."
