Non payment could include fraud. IMO he obtained some if not all the funds with promises of repayment on a certain date after doing certain things with the MMP.
At the same time, it is also possible that it was brought to PTSC's attention that TPL was using the MMP to support their own patents.
The reverse engineering of thousands of products will still have to be generated regardless, in order to prove infringement regardless of the work that has already been accomplished. All the products must be reversed engineered to prove liability.
To me the waste in shareholder funds is dealing with untrustworthy persons that will hurt your bottem line for gains on a patent that cannot stand on its own as has been done by selling TPL patents with the MMP as a backstop. How many more patents has he sold on his own since he stopped licensing the MMP? He manipulated Chuck Moore, he manipulated PTSC and he will continue to manipulate others to his advantage. This is the real waste to shareholder funds.
