To repeat myself again: IMHO this is the main reason, why the SP is suffering since two years. Patriot had to pay the huge bill, they built up over years, starting from 97 (thank you GE, I forgot this filing) until 2005, because they couldn't finance their business on sales of their technology, but only with the money from Swartz and thus us, the shareholders.
I know, I sound like a broken record, but the company had no choice at that time and they didn't have a choice the last two years:
Agreed, the subsequent dilution was necessary for the survival of PTSC, as was the arrangement to remove the remaing warrants, the price resets, and covertible debentures.
All that is needed now, in my humble opinion, is for Carlton Johnson to follow the sterling example set by David Pohl.
Be well
