A federal appeals panel on Tuesday challenged parts of a lower court's ruling for Carnegie Mellon University in a patent lawsuit against Marvell Technologies, ordering a new trial on a key question that could significantly reduce the lower court's massive award for the university. The ruling by the U.S. Court of Appeals for the Federal Circuit directed a lower court to review its 2012 order that Marvell pay $1.169 billion because it had willfully infringed two Carnegie Mellon patents for a chip technology.

The appeals court's ruling upheld the finding of patent infringement against Marvell but questioned whether the court had accurately calculated the damages. The appeals court affirmed just $278.4 million of the damage award, and ordered a new trial to re-calculate how much more the university is due.
