Wisconsin Alumni Research Foundation sues Apple for patent infringment involving the A7 chip
The Wisconsin Alumni Research Foundation is the division of the University that controls the school's patent portfolio. According to the Foundation, Apple used the patent in the A7 to improve the efficiency and performance of it. The suit asks Apple to stop infringing on the patent and wants the court to force Apple to pay monetary damages.
In the past, Apple has filed one or more patent applications using the '752 patent as relevant prior art, so it obviously was aware of its existence. So far,no judge has been assigned to this case, which we will follow as it progresses through the Wisconsin legal system.
