PTSC this could be big... SAN DIEGO, Apr 23, 2004 /PRNewswire-FirstCall via COMTEX/ -- Patriot Scientific Corporation (PTSC) , a developer and owner of core microprocessor technologies, announced today that it has sent notification to more than 150 additional companies of potential infringement of its U.S. Patent 5,809,336. The companies are among the world's largest electronics firms in the semiconductor, communications equipment, computer hardware, electronic instruments, computer peripherals, scientific and technical instruments, computer storage, computer networks and office equipment business segments.
Dr. Patrick Nunally, chief technical officer of Patriot Scientific, said, "The widespread use of U.S. 5,809,336 is becoming increasingly apparent across multiple industries. The mechanisms disclosed are essential to the operation of thousands of products. We believe that each of these violates PTSC's rights."
The notifications are intended to protect Patriot Scientific's patent rights. Patriot previously announced lawsuits filed against Sony, Fujitsu, Toshiba, NEC and Matsushita. The initial filings seek damages in excess of several hundred million dollars.
Patriot Scientific's patents describe the principal means used by the microprocessor industry to increase the internal operating speed of modern microprocessors. Patriot Scientific'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 Scientific'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 violates portions of Patriot Scientific's patent portfolio.
