A negative USPTO ruling would not be the end of the process as PTSC/TPL have rights to appeal that decision with the USPTO, and then even if that were to fail, take it to court. If you were Toshiba or Matsushita or NEC, would you give millions to a penny stock company known for giving divy's on the idea that you could get it back from them based on a beauracratic process that has no specific timing to it? I think that's an unlikely scenario. As the orders from the court state, these issues are RESOLVED. They're not pending on further action. If the J's want to go take advantage of the dismissal WITHOUT prejudice, they'd have to sue TPL/PTSC anew and start over, as I understand it. I suspect, they have bigger issues to deal with in business then to reopen a battle they've fought for the last 4 years, and decided to give up on.
Another thought, jave you considered that maybe the J's as part of the deal agreed to withdraw their requests for re exam? I don't think that's likely either but nobody seems willing to consider other options except that PTSC is getting screwed in this deal.
