Apple found liable for using University of Wisconsin's patent
Apple can't win every patent lawsuit it's involved with. Here's a good case in point: the tech giant has been found liable of using technology patented by the University of Wisconsin in 1998 without the proper permission. To be precise, that technology was designed to improve chip efficiency as you can see in this USPTO filing, and it was used in iPhones and iPads. The Wisconsin Alumni Research Foundation (WARF) filed a case against Intel back in 2008 for using the same patent, but it was immediately settled out of court. It launched the lawsuit against Cupertino in January last year.
