About Patriot Scientific

Patriot Scientific is an intellectual property company developing and marketing innovative and proprietary semiconductor technologies into the fast- growing hand-held wireless and smart card markets. The company's portfolio of patents encompasses what is believed to be fundamental microprocessor technology and includes additional patents pending to protect its technology and architecture. For more information please visit Patriot Scientific online at www.ptsc.com

The company has filed lawsuits against Matsushita, Sony, Fujitsu, Toshiba and NEC, seeking damages in excess of several hundred million dollars to protect patent rights contained in Patent No. 5,809,336 "High Performance Microprocessor Having Variable Speed System Clock." Patriot's patents describe the principal means used by the microprocessor industry to increase the internal operating speed of modern microprocessors. Patriot's patent portfolio encompasses the fundamental workings of well over $18 billion dollars worth of microprocessors sold in the United States last year. From the time the patents were issued, the company estimates that over $150 billion dollars worth of microprocessors have made use of Patriot's technology. The company believes that significant segments of the electronics industry are currently benefiting from technology owned by Patriot Scientific and that microprocessors operating at speeds above 110 - 120 MHz are in violation of portions of Patriot Scientific's patent portfolio.
