PTSC Patriot Scientific Notifies More Than 150 Companies of Patent Portfolio Infringement
Apr 26, 2004 (TelecomWeb News Digest/PBI Media via COMTEX) -- PatriotScientific Corporation (PTSC), a developer and owner of core microprocessor technologies, on Friday (April 23) 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.
Patriot Scientific CTO Dr. Patrick Nunally said, the widespread use of the company's patent 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 has previously filed lawsuits against Sony, Fujitsu, Toshiba, NEC and
Matsushita. The initial filings seek damages in excess of several hundred million dollars.
PTCS'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 violate portions of Patriot Scientific's patent portfolio.
