The last two paragraphs say it all:
"Mueller also agreed that InterDigital is valuable for just about any company in the high-tech sector because it includes not only a a sizable patent portfolio but a research and development group that produces many hundreds of new patent applications every year. With these patent researchers, Apple, Google, or Microsoft could accelerate the pace at which they obtains new patents.
Unfortunately for Google, Mueller doesn't think the search engine could outbid Apple for InterDigital. Apple has over $70 billion in the bank compared to just under $40 billion for Google."
Google is going to need serious help if they want Interdigital, and all of this saber rattling may have been a vain attempt to shoo people away from IDC.
