Patriot Scientific Corporation Announces Second Cash Stock Dividend in Less Than a Month

Annual Meeting and New Offices Also Announced SAN DIEGO--March 9, 2006--Patriot Scientific Corporation  today announced that it will issue yet another cash dividend for shareholders and qualified warrant holders of record as of March 31, 2006. This dramatic announcement follows closely on the heels of last month's announcement of the Company's first dividend payable on March 22, 2006. Patriot's earlier dividend was $0.02 per share - the new dividend is planned to be $0.04 per share.

The Company has been advised that it will likely receive the distribution of its share of the proceeds from recently announced patent portfolio license transactions by the end of March. Those transactions, announced within the past month, involved the Company's jointly owned Moore Microprocessor Patent(TM) (MMP) Portfolio having been successfully licensed - through its marketing alliance with The TPL Group's Alliacense division - to Casio Computer Co. Ltd. and Fujitsu Limited.

The Company expects to pay the dividend in late April, with the exact date to be determined and announced. Final information as to the number of shareholders and outstanding shares will be provided by the Company's transfer agent as of the record date, but based upon current information and estimates the Company will set aside funds of approximately $15 million for payment of the dividend when distribution of its share of licensing proceeds is received.

"I am delighted to speak on behalf of the Board of Directors in announcing this planned dividend, which will be double the amount of the previously declared dividend," said Patriot Scientific's Chairman and CEO, David H. Pohl. "The timing and amount of the payment to dividend recipients is subject, of course, to the Company actually receiving our expected share of the proceeds from the licensing transactions," Pohl continued.

"This second dividend announcement in less than a month - something extremely rare in the world of microcap stocks - is yet a further important step toward evidencing the faith and belief of the Board of Directors and management of Patriot Scientific in the Company's current financial strength and future potential," said Pohl. "We are pleased to be able to continue rewarding loyal shareholders with this additional, and even more significant dividend." The Company strongly believes that more licensing transactions and related revenues are likely, although none are assured. As in the instance of announcing this increased dividend, Patriot Scientific's Board of Directors will continue to consider and decide whether to take such dividend payment actions in the future, based on future revenues and the financial condition of the Company, as well as market conditions and other factors.

About the MMP(TM) Patent Portfolio

The patent portfolio, marketed as the Moore Microprocessor Patent(TM) (MMP) Portfolio, contains intellectual property that is jointly owned by publicly held Patriot Scientific Corporation and the privately held TPL Group. The portfolio encompasses seven U.S. patents as well as their European and Japanese counterparts. Protected through year 2015, these patents protect techniques used in designing microprocessors, microcontrollers, Digital Signal Processor (DSPs), embedded processors and System-on-Chip (SoC) implementations.

The MMP Portfolio is exclusively managed by Alliacense, a TPL Group enterprise. In light of the early validation of the MMP Portfolio by license agreements with marquee chip-makers Intel and AMD in 2005, followed by the announcement in 2006 of licenses with HP, Casio and Fujitsu, MMP licensing efforts are now focused on global system manufacturers.

Global sales of end products deploying chips using technologies protected by the jointly owned patents are estimated to be nearly $260 billion annually. Products ranging from televisions, digital cameras and portable music players to servers, medical equipment, and even automotive electronics systems -- are all designed with multiple semiconductor devices that use MMP Portfolio technologies.
