Apple Inc. has escaped a $506 million patent infringement judgment over semiconductor technology.

The U.S. Court of Appeals for the Federal Circuit on Friday threw out the judgment won by the University of Wisconsin's technology transfer arm in a 2015 jury trial. “No reasonable juror could have found infringement based on the evidence presented during the liability phase of the trial,” Chief Judge Sharon Prost wrote for a unanimous panel.

The case has been fought tooth-and-nail at trial and on appeal by Wilmer Cutler Pickering Hale and Dorr for Apple and Irell & Manella for the university. Wilmer partner William Lee and Irell partner Morgan Chu squared off for a marathon one-hour-and-40-minute hearing in July before the Federal Circuit.
