University of Wisconsin sues Apple Inc. (AAPL)

Posted Feb 4, 2014

Apple Inc. (NASDAQ:AAPL) is getting sued by The Wisconsin Alumni Research Foundation (WARF), which is in charge of patent licensing for the University of Wisconsin. WARF alleges that Apple’s A7 processor infringing on a patent developed by the university involving “the efficiency and performance of contemporary computer processors.” The patent in question is #5,781,752, which is called “Table Based Data Speculation Circuit for Parallel Processing Computer.” This patent was filed by Andreas Moshovos, Scott Breach, Terani Vijaykumar, and Gurindar Sohi.

The patent details a process that allows quicker execution of processor instructions by predicting dependencies based on previous mis-speculations detected at the final stages of processing. Sohi was the leader of the group and received the Eckert-Mauchly Award, which is a highly coveted prize for computer architects. Apple integrated the 64-bit A7 processor in the iPhone 5s, iPad Air, and iPad mini with Retina Display.

The lawsuit alleges that Apple was aware of the patent’s existence because it was cited in several of Apple’s newer patents that were issued. WARF believes that Apple incorporated the technology of the patent into the A7 processor to achieve enhanced efficiency. WARF is asking the court to prevent Apple’s unauthorized use of the patent. WARF is seeking an injunction that prevents Apple from using the technology without a license along with monetary damages, interest, and legal fees.
