Trade Commission finds no literal patent infringement by Gateway PC maker Gateway said Thursday it won an appeal by the U.S. International Trade Commission, which overturned an earlier ruling that Gateway-branded PCs infringed on patents held by Hewlett-Packard involving parallel port technology.The ITC remanded the case to an administrative law judge for further proceedings on issues raised by both companies. The ITC’s action this week overturned that finding after the commission found there was no literal infringement by Gateway.The case stemmed from a 2004 decision by HP to assert seven patents against Gateway, it said. Three of HP’s patent claims were dismissed prior to trial, and Gateway prevailed outright on two others. The only claim that stuck was a finding in August of infringement on legacy circuitry that would allow use of an outmoded printer technology using a parallel port, Gateway said, which the company’s appeal overturned. The ITC overturned that finding after it found there was no literal infringement by Gateway, the PC maker said. Gateway and HP are engaged in intellectual property litigation in five venues around the U.S., Gateway said. Technology Industry
