Cox Communications, Inc. v. Sony Music Entertainment

Issues: (1) Whether the U.S. Court of Appeals for the 4th Circuit erred in holding that a service provider can be held liable for "materially contributing" to copyright infringement merely because it knew that people were using certain accounts to infringe and did not terminate access, without proof that the service provider affirmatively fostered infringement or otherwise intended to promote it; and (2) whether the 4th Circuit erred in holding that mere knowledge of another's direct infringement suffices to find willfulness under 17 U.S.C. § 504(c).
