"So... What is TPL waiting for??"
Money to prosecute.
No one will pay up until our current case is taken to conclusion with a large settlement, or a settlement between the parties with large dollar amounts. Why would anyone sitting on the sidelines pay until they have to. It would seems TPL is asking for larger dollar amounts now. Of course that is just a guess, but it would seem reasonable. Now the question would be... when can infringers be considered to be willful infringers and be charged triple damages? Is it after the NIRC, or is it after the first litigates are found guilty? Perhaps all are waiting on developments before proceeding. I think that is what I would do if the dollar amounts were now higher.
It seems obvious to me that we don't have the cash on hand now to litigate with others at this time and why should we until this case come to conclusion.
