"Wisconsin's complaint notes that Apple has cited the '752 patent in some of its own patent applications (meaning that Cupertino was aware of the patent), but rebuffed WARF's approaches seeking a licensing deal."
That seems to be an on-going theme with Apple. Hopefully Wisconsin University won't let Apple get away with it and sees this to the end. They could easily get triple damages as Apple knew they were infringing and thus it was willful. Since it is also not FRAND, the sky is the limit for licensing. They could make the A7 and any successor to it quite expensive. Even better, when Apple loses, they could get a court order barring Samsung from selling the CPU to Apple until the fines and all licensing fees are paid.
I would bet that the PA Semi guys at Apple are working on a new chip that doesn't violate that patent but we all know, it won't be coming out tomorrow.
