Marvell Technology Group Ltd has failed to convince a federal judge to reduce by more than half a $1.17 billion jury verdict for infringing two hard disk drive patents held by Carnegie Mellon University. U.S. District Judge Nora Barry Fischer in Pittsburgh, where Carnegie Mellon is based, on Tuesday denied Marvel’s bid to cut about $620 million from the award on the basis that the university unreasonably delayed pursuing its claims for patent infringement. Marvell had contended that Carnegie Mellon had constructive knowledge of the allegedly infringing products six years before the lawsuit was filed in March 2009. Carnegie Mellon countered that it had at most heard “rumors” or “suspicions” that its patents were being infringed.
