The act of making available movies for P2P copying should itself give rise to damage liability, with no need for a showing that anyone actually came along and availed themselves of the illicit property, Hollywood moviemakers are arguing. “It is technologically infeasible to determine whether the public is copying an open share folder, although the RIAA makes its own downloads from defendants’ share folders, produces screen shots and, among other things, captures an IP address. An Arizona judge ruled last month in a different case that those downloads count against a defendant, a one-of-a-kind decision being appealed on grounds that the RIAA was authorized to download its own music.” Infringement penalties can run to $150,000 per copyright violation.
