Patriot Scientific Corporation Announces Three Purchases of Moore Microprocessor Patent(TM) Portfolio Licenses

Patriot Scientific Corporation Announces Three Purchases of Moore
Microprocessor Patent(TM) Portfolio Licenses

CARLSBAD, Calif., Oct. 5 /PRNewswire-FirstCall/ -- Patriot Scientific
Corporation (OTC Bulletin Board: PTSC) announced today three new MMP(TM)
Portfolio licensees less than three weeks after the USPTO announced its
decision to affirm the validity of US'336, the most widely recognized patent
in the MMP Portfolio. The new licensees include Harman International, TPV
Technology, and Textron Inc., and will result in both upfront and future
payments.

The agreements follow a string of successes in the reexamination of the MMP
Portfolio(TM) patents by the USPTO and German Patent Court. In the past 9
months, the German Patent Court affirmed the validity of EP'730, and the USPTO
has affirmed the validity of both US'584 and most recently US'336.

Despite the risk of willful infringement in cases where companies delay
licensing decisions on the basis of reexams, companies have been awaiting the
outcome of US'336 and are now reengaging in licensing discussions in light of
the escalating royalty rate structure of the MMP Portfolio(TM) Licensing
Program.

Harman Industries is a worldwide leader in the manufacture of high-quality,
high-fidelity audio and electronic products for automotive, consumer and
professional use. TPV Technology is a leading display solution provider,
specializing in design and production of a wide spectrum of desktop monitors
and LCD TVs. Textron Inc. is one of the world's best known multi-industry
companies, consisting of numerous subsidiaries and operating units and known
by familiar brand names, including Bell Helicopter, Cessna Aircraft, Greenlee
and E-Z-GO, among others.

The MMP Portfolio patents cover techniques that enable higher performance and
lower cost designs, and are fundamental to consumer and commercial digital
systems ranging from DVD players, cell phones and portable music players to
communications infrastructure, medical equipment and automobiles, which today
have dozens of microprocessor-based features and benefits.
