Note Regarding Settlement from CEO Jim Turley

Shareholders are advised that the following is the only information that will be provided by Patriot Scientific Corporation regarding the resolution of the Texas (and California) litigation that had been pending regarding the MMP portfolio patents subject to the dispute:

Patriot Scientific Corporation, its directors, officers and employees are obligated to observe the confidentiality provisions of the settlements and will limit any comments or statements solely to references to the wording of the joint press release or statements that matters between the parties to the litigation have been settled.

This settlement occurred during Patriot's current financial quarter, which ends February 28, 2008, and for which financial reports will be due for filing with the SEC by the second week of April, 2008. Information applicable to this settlement will be included in those reports to the extent required of the company, yet consistent with the confidentiality restrictions imposed by the settlement pursuant to guidance from Patriot's professional legal and accounting advisors.

In addition, consistent with applicable securities laws and Patriot's insider-trading policy, the company's directors, officers, employees and consultants who have knowledge of the terms of settlement are restricted from trading in PTSC shares until after the company's quarterly financial reports are publicly filed next April.

We realize that our shareholders may expect that the details of the settlement should be made available to them, or that Patriot's board and management might provide at least general comments or further press releases on the subject. We understand this and would do so if permitted, but in order to honor our legal commitments regarding confidentiality, we have said all we can say.
