Is Apple stepping on a universitys toes with its A7 processor design? The Wisconsin Alumni Research Foundation (WARF) has filed suit against the company, claiming that the iPhone 5S, iPad mini with Retina Display, and iPad Air all benefit from an information processing system developed at the University of Wisconsin – Madison and patented in 1998. The lawsuit asks for unspecified damages and an injunction stopping the sale of any product containing the A7 processor without a licensing payment — both are standard requests for these lawsuits, although WARF is asking for damages to be tripled because Apple knew of the patent and therefore willfully infringed on it. WARF, an independent group that acts as the universitys patent enforcement arm, has a mixed reputation.
