Sony, Universal, and Warner Bros sue Cox Communications accusing the ISP of profiting from piracy by not disabling accounts of known and persistent infringers
For more than a decade, copyright holders have been sending takedown notices to ISPs to alert them that their subscribers are sharing copyrighted material.
Context & Ripple Effects
By 2018 the labels had spent over a decade sending takedown notices to ISPs, and they had already beaten Cox once: a court had affirmed a $25M judgment against Cox for its customers' infringement two years earlier. This new suit escalates from damages to business model — the claim is that Cox kept known repeat infringers online because their subscription fees were revenue.
The filing opened a template the industry ran repeatedly: the same labels sued Charter on an identical profits-from-piracy theory within a year (suing Charter), Frontier eventually chose settlement over trial, and the Cox case itself climbed to the Supreme Court — where the Trump administration's brief backed Cox's argument that unproven infringement claims shouldn't force terminations.
First-order effects
- Cox now faces litigation built on its own subscriber revenue: every account it declines to terminate becomes evidence that it profited from infringement, on top of the $25M it already owes.
- Sony, Universal, and Warner gain a second lever beyond damages — a court order compelling account terminations would let rights holders outsource enforcement to ISPs at no cost to themselves.
Second-order effects
- The labels replicate the playbook against Charter within months, turning 'repeat infringer termination' from a Cox-specific grievance into a standard demand across major US ISPs.
- ISPs without Cox's litigation appetite take the settlement path — Frontier's later settlement shows the pressure lands hardest on smaller broadband providers who can't fund a Supreme Court defense.
Third-order effects
- The strategy culminates in a Supreme Court decision limiting ISP liability in the Cox case, after which music publishers drop their parallel Verizon suit — the termination-by-lawsuit era effectively closes.
- Enforcement migrates back upstream toward services and platforms (as in the SET TV action) rather than access providers, leaving the notice-and-takedown regime as the primary ISP-facing tool.
The trend: Copyright holders' decade-long campaign to convert ISPs into piracy enforcers through repeat-infringer lawsuits crested with the Cox litigation and was rolled back by the Supreme Court's liability limits.
