I have heard some financial writers say this company rivals Qualcomms IP. That is far more extensive than a mere Nortel.
I haven't accessed or found any articles which argue IDCC is less than nortel and several that have stated they are superior. Most that side with superior say so because they are for the newer tech. like 4G and LTE.
You can find them on this mb if you can sort through all the hoopla that has been posted lately.
