Patriot Scientific Files Form 10-KSB for Fiscal Year 2006

Carlsbad, CA, Oct. 13, 2006 - Patriot Scientific Corporation today filed its 10-KSB annual report for its fiscal year ending May 31, 2006. The report, filed with the U.S. Securities and Exchange Commission, includes audited financial statements for its fiscal year and related disclosures concerning the company's results of operations and financial condition during that period.

Patriot Scientific's consolidated financial statements reflect net income of $28,672,688 for the fiscal year ending May 31, 2006, with revenue of $35,895,449 million as its share of distributions from licensing agreements related to the MMP Patent Portfolio. The report also discloses that during the period June 1, 2006 through October 3, 2006, Phoenix Digital Solutions, which is jointly owned by Patriot Scientific and the TPL Group, entered into MMP portfolio license agreements with third parties, pursuant to which Phoenix Digital received aggregate proceeds totaling $32,699,000. The dollar amount for each licensing deal varies and is dependent on the relevance of the patents to each licensee's revenue and the extent to which the patented technology is incorporated into specific products, rather than on the total revenue from all products of the licensee.

Patriot Scientific and The TPL Group are co-owners of the MMP Portfolio, which Alliacense™, a TPL Group enterprise, exclusively manages. The MMP Portfolio patents, filed in the 1980s, protect design techniques that have become essential to a myriad of consumer and commercial digital systems ranging from DVD players, cell phones and portable music players, to communications infrastructure, medical equipment and automobiles.

"Patriot Scientific has undergone tremendous positive change in the last year," said David Pohl, Patriot Scientific chairman and CEO. "The shift away from developing and marketing our own Ignite microprocessor to focus primarily on revenue from the licensing of our patent portfolio has bolstered the financial strength of the company. We are excited about the next phase of our plan that has already begun in which we are evaluating opportunities to diversify our revenue stream through possible joint ventures or acquisitions, all with the goal of increasing shareholder value."

Activities at Patriot Scientific that have occurred thus far in calendar year 2006, which includes the last six months of the fiscal year covered in the10-KSB include:

• 9 MMP portfolio licenses have been sold in the first 9 months of the year
• Over 300 companies have been notified that they are licensing candidates
• Unprecedented among Micro cap stocks, 2 cash dividends in 2006
• Announced open market buy-back program for shares
• Conversion and retirement of all outstanding debentures

Due to activities related to preparation and filing of restated financials for fiscal 2002 through 2005 as previously announced, Patriot Scientific has filed a notice to take the allowable five-day extension to file the fiscal 2007 first quarter 10-Q financial report for the three month period ending August 30, 2006. That document will be filed October 23, 2006. Patriot Scientific has been advised that the character "E" that has been appended to the company's trading symbol pending the filing of the company's annual report will be removed today.
