Viacom on Friday said it would appeal its loss to YouTube in a Second US Circuit Court of Appeals after attempting to sue the video site for copyright infringement. It argued that the court incorrectly interpreted the Digital Millennium Copyright Act by ruling that YouTube had followed safe harbor guidelines by initially dealing with piracy only by responding to takedown requests from Viacom and others. The judge's statement that YouTube "welcomed" piracy, even if it took down violators, was proof the DMCA didn't apply, Viacom said.
