Patriot Scientific Cancels Presentation at Westergaard Investment Conference

Speculative Buy Rating Reiterated

Patriot Scientific Corporation (Patriot Scientific) cancelled their presentation at the Paulson Investment Company 30th Annual
Westergaard Conference on Tuesday, November 13, 2007, at the Waldorf Astoria Hotel in New York City. No reason for the
cancellation was given. The cancellation comes two days after the company cancelled a web-cast by James Turley, Pres./CEO, that was to be given on November 7, 2007.

SUMMARY

A 30-day stay has been granted in the litigation for Technology Properties Limited (TPL) and Patriot Scientific vs. Matsushita Electric Industrial Co., Ltd., et al. Since the 30-day stay granting, rampant speculation of a possible settlement has pushed Patriot Scientific's common stock up over 70% from a recent intra-day low of $0.38 per share set on October 26, 2007, to an intra-day high of $0.65 yesterday, November 8, 2007. Volume on the up move has been massive. We deign to join in speculation of a settlement, since if there is one, the terms will need to be analyzed as to the effect on Patriot Scientific's 50% net receipts and future possible settlemets. Further, there may be other reasons for this PR lock-down. TPL has the right of review and possible approval on news releases and we assume public presentations. An event that overhangs Patriot is the final ruling by the U.S. Patent and Trade Office (USPTO).

While we reiterate our Speculative Buy Rating and our $0.75 price per share target for Patriot Scientific, the stock may need to digest this 70% up move and we urge caution, keeping in mind any forthcoming news releases.
