Have the new "joint owners" from the Nortel patent sale agreed to subject any of these patents to litigation?
Philadelphia-based intellectual property lawyer Patrick Igoe called the winning bid a "staggering amount of money," though he noted that each company in the consortium could have paid $750 million each, significantly less than Google's original $900 million bid. It's not clear if each company contributed equally or will equally share in ownership of the patents in question. However, it seems likely all six companies have agreed to some sort of mutual licensing agreement.
