Item 8.01         OTHER EVENTS.

On September 23, 2005, Lowell Giffhorn, a former executive officer and a current
director of Patriot Scientific Corporation (the "Company"), submitted a demand
for arbitration with the American Arbitration Association related to the
termination of Mr. Giffhorn's employment with the Company. Mr. Giffhorn asserts
that the termination of his employment with the Company was unlawful,
retaliatory, wrongful, violated public policy, violated the covenant of good
faith and fair dealing and violated securities laws. Mr. Giffhorn demands
damages of $1,500,000, which amount constitutes approximately 25% of the
Company's current cash reserves. The Company intends to vigorously defend itself
with regard to these claims. The parties are currently in the process of
selecting arbitrators. The amount, if any, of ultimate liability with respect to
the foregoing cannot be determined. Despite the inherent uncertainties of
litigation, the Company at this time does not believe that the foregoing will
have a material adverse impact on its financial condition, results of
operations, or cash flows.
