Apple was found liable of using a 1998 patent owned by University of Wisconsin in its A7, A8, and A8X processors included in the 2013 and 2014 iPhone and iPad lineup without getting proper permission. The patent involves a technology that was designed to improve chip efficiency.
Last year, the Wisconsin Alumni Research Foundation (WARF), which protects the University of Wisconsin’s intellectual rights and patents, sued Apple for infringing on one of its processor patents. Reuters reports that a Wisconsin jury today found Apple guilty of infringing on the patent owned by WARF, and as a result, the Cupertino-based company could be forced to pay up to $862 million in damages. The jury also ruled that the patent was valid, negating Apple’s argument that it was invalid and no infringement had taken place.
Cupertino, California-based Apple denied any infringement and argued the patent is invalid, according to court papers. Apple previously tried to convince the U.S. Patent and Trademark Office to review the patent’s validity, but in April the agency rejected the bid.
According to a recent ruling by U.S. District Judge William Conley, who is presiding over the case, Apple could be liable for up to $862.4 million in damages.
Granted in 1998, the patent in question covers a method for improving processor efficiency and is titled “Table based data speculation circuit for parallel processing computer.” It lists several current and former University of Wisconsin researchers as inventors.
According to Reuters, the court is slated to try the case again to determine how much Apple should pay the University and the judge presiding over the case believes it could be as much as $862.4 million in damages, but even the full amount will not make a dent in Apple’s finances.
The legal battle between Apple and University of Wisconsin is far from over yet, though. The Wisconsin Alumni Research Foundation (WARF) has also filed a second lawsuit against Apple for the same patent, accusing the company of using the technology in the A9 and A9X found in the iPhone 6s, 6s Plus, and iPad Pro. The University of Wisconsin has filed a similar case against Intel back in 2008 for using the same patent, but it was immediately settled out of court.
