Dutton Associates Announces Investment Opinion: Patriot Scientific Rating and Price Target Maintained By Dutton Associates

Dutton Associates continues its coverage of Patriot Scientific (OTCBB:PTSC) maintaining its rating and price target at Speculative Buy and $.75 respectively. The 15-page report by Dutton senior analyst Richard W West, CFA is available at www.jmdutton.com as well as from First Call, Bloomberg, Zacks, Reuters, Knobias, and other leading financial portals. Patriot Scientific Corporation’s new business course began in June 2005, after a change in top management, when the Company began to execute its new strategy to become a dedicated intellectual property (IP) company by licensing the portfolio of microprocessor patents which run until 2015. Patriot Scientific has granted licenses for the portfolio of microprocessor patents to 20 major microprocessor manufacturers, either directly or through the partnership with TPL, detailed in the report. Patriot Scientific cleaned up its balance sheet in 2006 and its balance sheet as of May 31, 2007, is quite strong, with a current ratio of over 15.5 to 1 and working capital of $ 29.4 million. Patriot Scientific’s potential for royalty revenue, while specifically incalculable, is quite large. Patriot Scientific’s patents address a large potential market of over 500 electronics manufacturers. Over 300 manufacturers already have been put on notice for possible infringement of the microprocessor patents. This report details the current status of Patriot Scientific, the current status of the litigation against Matsushita Electric Industrial Co., Ltd., et al, the U.S. Patent Office reexamination of Patriot Scientific’s patents, and the possible risks involved in an investment in Patriot Scientific. We believe that at the current market value, the major potential from continued royalty revenue, the progress made in repurchasing its outstanding warrants, and the securing of a partner to develop the technology of its subsidiary Holocom, outweigh the risks and we reiterate our Speculative Buy rating.
