I could see TPL wanting to reverse merging with PTSC just so they can go public.

Plus the revenues would no longer be split and they get the entire pot.

I think PTSC got a heck of deal of allowing TPL to handle the licenses...meaning they have alot less expenses...and TPL had the better infrastructure to get it moving faster.  Sure they lose control of some of the process of the licensing, but i think TPL has been doing a good job of getting companies on board.
