Cox Communications, Inc. v. Sony Music Entertainment

This civil copyright case arose from claims by major record labels that Cox Communications, a U.S. internet service provider, knowingly contributed to and profited from widespread music piracy by failing to terminate repeat infringers. In 2019, a federal jury in Virginia awarded the plaintiffs $1 billion in statutory damages. Cox appealed, arguing it was entitled to DMCA safe harbor protection and that the damages were excessive. The Fourth Circuit partly vacated the award and remanded. The case has continued through post-remand proceedings, with a significant hearing or ruling reported on March 25, 2026. The litigation tests the boundaries of ISP liability for user infringement and the availability of safe harbor defenses under U.S. copyright law.

The original $1 billion jury verdict was vacated in part by the Fourth Circuit and remanded for recalculation of damages. As of March 25, 2026, the case remains in active litigation with no final public judgment.

The main disputes are whether Cox qualified for DMCA safe harbor protection, whether its failure to terminate repeat infringers constituted willful contributory infringement, and how statutory damages should be calculated.

The case has shaped ISP copyright enforcement policies, encouraging stricter repeat-infringer termination procedures and influencing how courts interpret the DMCA safe harbor, while raising concerns about the balance between copyright protection and internet access.
