Apple has been reportedly sued for infringing on a processor design patented by the University of Wisconsin back in 1998.
The Wisconsin Alumni Research Foundation (WARF) has filed a lawsuit against the company, claiming that the iPhone 5S, iPad mini with Retina Display , and iPad Air all benefit from an information processing system developed by researchers at the university.
According to The Verge, the lawsuit asks for unspecified damages and an injunction stopping the sale of any product containing the A7 processor without a licensing payment.
WARF, an independent group that acts as the university's patent enforcement arm, has asked for damages to be tripled because Apple knew of the patent and thus, willfully infringed on it.
The report said that whether Apple infringed on the design, and what the patent covers, is still undisclosed.
