I'm not sure I agree with you on the reasons.  From Turley's note:

"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."

This specifically references the settlement terms, NOT any other license deals that were signed previously.  It's from that perspective that I was thinking.  The only difference between this deal and the Fujitsu, HP, Sony, or any other deal for that matter is the fact that they have been restricted from trading the shares until AFTER the terms are released, while in the past, they seemed to be able to trade without any specific ties to other license numbers being revealed.
