A U.S. Department of Justice (DoJ) official has joined the debate surrounding Apple Computer\u2019s proprietary digital music technology by criticizing European antitrust activities, but groups attacking Apple are defending their actions.Speaking in Washington, D.C., on Wednesday, Thomas Barnett, assistant attorney general at the DoJ\u2019s antitrust division, warned that forcing companies to reveal their intellectual property stifles innovation. He used Apple as an example, in a nod to growing discontent in Europe regarding the way that music purchased from iTunes is tied to the iPod. Architects of complaints against Apple in Europe say he\u2019s got it wrong. "We\u2019re not attacking intellectual property rights, but saying they should be implemented in a way which doesn\u2019t dictate which player you use," said Torgeir Waterhouse, a senior adviser with the Norwegian Consumer Council. His organization filed a complaint to Norway\u2019s consumer representative, or ombudsman, arguing that it\u2019s illegal for Apple to limit iTunes customers to playing music from the store exclusively on iPods. Along with similar representatives in Denmark and Sweden, the Norwegian ombudsman asked Apple to defend its policy. In a written reply, Apple said it won\u2019t budge on the issue, but the company plans to meet representatives from the countries later this month to further discuss it. If Apple won\u2019t open up, the ombudsman will take the company to court.Waterhouse suggests that Apple could solve the problem by licensing its digital rights management technology to other device makers so that iTunes customers could choose among devices or opt for an open standard that would be compatible with more devices. Barnett\u2019s criticisms of European antitrust policy, including comments that the policy is aimed at helping competitors instead of consumers, are generally in line with comments from U.S. officials since the Bush administration came to power, said Scott Megregian, a partner and head of the European competition group in the law firm McDermott Will & Emery UK. He disagrees with the argument that requiring companies to open up some of their technology stifles innovation. "That\u2019s an argument without support," he said. "Microsoft hasn\u2019t stopped innovating that I can tell, despite regulations and attack by the E.U."So far, the European Commission has likely communicated with the countries that are pursuing Apple and has probably expressed an opinion on the matter, he said. While no official complaints have been filed with the commission, if one is, the result will have the makings of a historical battle. "This has the potential to be the next big high-profile dispute," Megregian said.-Nancy Gohring, IDG News Service (Dublin Bureau)Related Links:\n\nNordic Consumer Groups May Team Against iTunes\n\nApple Touts New iPods, Movie DownloadsCheck out our CIO News Alerts and Tech Informer pages for more updated news coverage.
