Apple Inc 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 without permission in chips found in many of its most popular devices.

The jury in Madison, Wisconsin also said the patent, which improves processor efficiency, was valid. The trial will now move on to determine how much Apple owes in damages.

Representatives for the Wisconsin Alumni Research Foundation (WARF) and Apple could not immediately be reached for comment.

WARF sued Apple in January 2014 alleging infringement of its 1998 patent for improving chip efficiency.
