Apple could be facing up to $862 million in damages after a U.S. jury on Tuesday found the iPhone maker used technology owned by the University of Wisconsin-Madison's licensing arm. WARF sued Apple in January 2014 alleging infringement of its 1998 patent for improving chip efficiency.
The jury was considering whether Apple's A7, A8 and A8X processors, found in the iPhone 5s, 6 and 6 Plus, as well as several versions of the iPad, violate the patent.
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.
The trial will now move on to determine how much Apple owes in damages.
Last month, WARF launched a second lawsuit against Apple, targeting the company's newest chips, the A9 and A9X, used in the new iPhone 6S and 6S Plus, as well as the iPad Pro.
