In a significant development in the ongoing legal battle between Cox Communications and major music labels, a coalition of former copyright officials, media industry groups, and ex-legislators has submitted nearly a dozen amicus briefs to the U.S. Supreme Court. These briefs advocate for holding internet service providers (ISPs) accountable for their customers’ online piracy activities.
The case centers on allegations that Cox Communications failed to adequately prevent its subscribers from engaging in copyright infringement. In 2019, a Virginia jury found Cox liable for its customers’ violations of over 10,000 copyrights belonging to labels including Sony Music Entertainment, Warner Music Group, and Universal Music Group, resulting in a $1 billion verdict. However, in February 2024, the 4th U.S. Circuit Court of Appeals overturned the damages award, deeming it unjustified, but upheld the finding that Cox willfully infringed copyrights. The court ordered a new trial to reassess the appropriate amount of damages.

In August 2024, Cox petitioned the U.S. Supreme Court to review the ruling that held the company responsible for its users’ music piracy. Cox argued that the decision had created “confusion, disruption, and chaos on the internet” and contended that it should not be held liable for the actions of its subscribers.

In June 2025, the Supreme Court agreed to hear the case, setting the stage for a landmark decision that could redefine the responsibilities of ISPs in preventing online piracy.

The recent amicus briefs filed by former copyright leaders and media groups emphasize the importance of holding ISPs accountable to deter widespread copyright infringement. They argue that ISPs play a crucial role in the digital ecosystem and have the capacity to implement measures that prevent or mitigate piracy. The briefs suggest that without such accountability, the creative industries could suffer significant economic harm due to unchecked online piracy.
Conversely, Cox Communications and its supporters, including a coalition of tech companies such as Google, Amazon, Microsoft, Mozilla, and Pinterest, argue that imposing liability on ISPs for user actions could lead to overbroad and unpredictable liability rules. They contend that such a precedent could force ISPs to terminate internet services for entire households or businesses based on allegations of infringement, potentially affecting innocent users.

The U.S. government has also weighed in on the matter. In May 2025, the Solicitor General submitted a brief arguing against holding ISPs liable for copyright infringement by their users. The brief suggested that such liability could lead to widespread terminations of internet service and pose challenges to the fundamental principles of internet access.

As the Supreme Court prepares to hear arguments in this case, the outcome is poised to have far-reaching implications for the responsibilities of ISPs, the enforcement of copyright laws in the digital age, and the balance between protecting intellectual property and ensuring broad access to internet services.
