No. 24-171Mar 25, 2026CommerceReversed

The question

Whether an internet service provider is contributorily liable for its users' copyright infringement when it neither induced the infringement nor provided a service tailored to infringement.

Cox Communications, Inc. v. Sony Music Entertainment

What the Court decided

The Court reversed and held that Cox is not contributorily liable for its users' infringement of Sony's copyrights. Contributory liability requires that the provider intended its service to be used for infringement, which can be shown only if the provider induced the infringement or provided a service tailored to that infringement. Cox did neither. The Court declined to expand secondary copyright liability beyond the forms recognized in its precedents.

The Court's opinion

Thomas, joined by Roberts, Alito, Kagan, Gorsuch, Kavanaugh, Barrett

The Copyright Act does not expressly impose liability for infringement committed by another, and Congress imposes secondary liability expressly when it intends to. The Court recognizes only the forms of secondary copyright liability that predated the Act and is unwilling to expand liability beyond those precedents. Contributory liability requires intent that the service be used for infringement, which can be shown only by inducement or by a service tailored to infringement. Cox neither induced its users' infringement nor provided a service tailored to infringement, so it is not contributorily liable.

Concurring in the judgment

Sotomayor, joined by Jackson

Sotomayor agreed that Cox is not contributorily liable but wrote separately, concurring in the judgment rather than joining the Court's reasoning.
