j70k:"I don't know what a fair price would be," I don't know the answer but I do know IDCC will never get what IDCC is worth. That you can bank on.
As I have said before why sell now. Who ever (?) buys IDCC the stock will forever be tied to that stock. If as you say the market turns south, then the company that buys IDCC will go south with the market also. So what have you gained??? If you just want to play IDCC, no need to sell the company to do it. It has been played from the start. It is in play almost everyday. Play it.
The bigger question is How High will IDCC go before it splits and goes higher? Do you want to take the chance and miss out on stock that can go threw the roof or do you want to settle for pennies on the dollar and sell out cheap??? Because that is all you will "pennies on the dollar." IMO stay & ride the IDCC train to the end of the line!!!
