"But, I still would like to know why Deutsche Telekom has not bought a license? I'd expect a large payment from them."

I would have too....but there is no sense of urgency on the part of infringers with all the uncertainty surrounding TPL/Alliacense, PTSC, Moore, PTO. Lawsuits between each other, lack of revenues for enforcement etc., etc. has diminished the need for anyone to license. I have been absent the board and thank God in order to protect my sanity regard my PTSC shares. We need and deserve some insight from Patriot on all issues NOW! No more of ...we can't comment on PTO or ongoing court issues. What the heck do we have to lose? By the way, I am convinced there are shenanigans going on at the USPTO! Bet on it!
