ISP Copyright Liability: SCOTUS Rules Knowledge Alone Isn't Enough in Cox v. Sony

# ISP Copyright Liability: SCOTUS Rules Knowledge Alone Isn't Enough in Cox v. Sony

> **Quick answer:** On March 25, 2026, the Supreme Court unanimously reversed a $1 billion copyright verdict against Cox Communications, ruling that internet service providers cannot be held liable for users' piracy simply because they knew infringement was happening. The Court established that contributory copyright liability now requires proof of active intent — not just awareness. This landmark ruling reshapes how copyright holders pursue enforcement and how platforms protect themselves going forward.

The Supreme Court just handed the internet industry one of its biggest copyright wins in two decades. The ISP copyright liability ruling in Cox Communications v. Sony Music Entertainment (2026) establishes a new legal standard — "knowledge is not complicity" — that will ripple through every corner of the digital economy, from your cable provider to the streaming service you subscribed to last week.

Here is what happened, why it matters, and what it means for creators, platforms, and ordinary internet users.
