Wanda,
QCOM won a court case that established that if you want to make a 2G phone you have to license with QCOM. That gave them the leverage to negotiate a good rate. You may want to look at QCOMs negotiations with Nokia regarding 3G to see that there is no Svengali negotiator that can get the big boys to sign without great effort and legal challenges.
Read the analysts reports on IDCC, especially Tom Carpenter of Hillyard Lyons. Tom has followed IDCC for a long time and has an excellent understanding of the situation. If you need help finding them I'm sure others here can point you to them.
If you can stand a lot of volitility, I suggest you buy at these levels. Risk/Reward is very positive in my opinion, short term and especially long term.
