TPL is PTSC's partner, anything effecting TPL financially could be important to PTSC. (in my opinion). From pg. 32 of the most recent 10Q

We May Be Required To Fund Our Joint Venture’s Legal Costs.

On March 20, 2013 TPL filed a petition under Chapter 11 of the United States Bankruptcy Code. While TPL’s petition does not affect the licensing agreement between PDS and Alliacense, PDS has incurred increased third-party legal costs as the litigation with HTC Corporation, and Acer, Inc., in the U.S. District Court, and the actions with the ITC Investigation No. 337-TA-853 progress. If PDS does not receive sufficient licensing revenues to pay these expenses, we may be required to pay these expenses. In the event the cost of the U.S. District Court and ITC Investigation actions exceeds our ability to fund these efforts, our options for additional sources of financing may be limited.
