Patriot Scientific Reports First Quarterly Profit In Its 18-Year History; Successful Licensing Credited With Dramatic Economic Turn-Around

Business Wire, April 5, 2005

SAN DIEGO -- On March 31, in its first quarterly Webcast, Patriot Scientific Corporation (OTC Bulletin Board: PTSC) announced it's first-ever quarterly profit - a major step forward for a company that recently signed a major licensing agreement with AMD (NYSE: AMD).

PTSC has also recently received from The Embedded Microprocessor Benchmark Consortium (EEMBC) the highest-ever ConsumerMark(TM) performance rating on its IGNITE(TM) microprocessor. EEMBC is an independent microprocessor testing, benchmarking and evaluation organization.

Revenue for the third quarter, which ended February 28, 2005, was approximately $2.9 million. This is up dramatically from revenue of $3,384, the amount reported for the period which ended February 29, 2004. Net income for the third quarter was approximately $600,000, compared to a net loss for the third quarter of fiscal 2004 of $975,894.

"This first ever quarterly profit," according to Jeff Wallin, president and chief executive officer, is an important milestone for Patriot Scientific Corporation. "For several years, the board and management team have been aggressively pursuing a carefully-crafted two-pronged strategy, first, to license the IGNITE(TM) technology and, second, to enforce its patent portfolio. Both strategies are designed to increase revenue and add shareholder value."

"This first-ever profit was the direct result of our entering into several licensing agreements with AMD," Wallin said. "We are pursuing licensing for both our core technology, IGNITE(TM), and for our patent portfolio of seven issued patents, and our license agreement with AMD covers both IGNITE(TM) and our patent portfolio."

"On behalf of our 5,809,336 patent," Wallin explained, "we are aggressively pursuing licensing revenue from companies that have been using our design without a license. We have begun licensing and promoting our newly evaluated world-class IGNITE(TM) microprocessor. AMD's endorsement of PTSC through its licensing of both our IGNITE(TM) and patent portfolio earmarks a positive inauguration of our long term growth strategy."

IGNITE(TM), the revolutionary ultra-low-power array microprocessor, intended primarily for the hand-held battery-powered applications market, received what is essentially a "best-we've-ever-tested" ConsumerMark(TM) rating from EEMBC in December, 2004; and in March, 2005, Patriot successfully completed the GNU C/C compiler software that will pave the way for IGNITE's adoption by manufacturers.

"With those accomplishments, and with AMD's recent licensing of this technology, we look forward to significant gains in market share for our core technology," Wallin concluded.
