I try not to give advice on Portfolio Management. At any point in time virtually anything can happen to just about any stock and to the overall market as well (ie 9/11 terrorist acts).
However, I think IDCC is about the most undervalued stock I have ever encountered. They have $13/share cash in the bank, they are earning $3.50/share and they have IP that covers the 3G market, the M2M market, the LTE/4G market, and they have IP that can assist carriers in solving the bandwidth crunch. I personally don't see why IDCC isn't selling in the low 50's right now.
Take that free opinion for what you paid for it.
