The DEFEND IP Act of 2026 creates a new legal mechanism for copyright owners to combat foreign websites engaged in digital piracy. Under this law, copyright holders can petition federal district courts to designate foreign websites as "digital piracy sites" if the courts find evidence of copyright violations and irreparable harm, with these designations lasting 360 days unless renewed. Once a site is designated, copyright holders can then request court orders requiring U.S. broadband providers and domain name service providers to block access to those sites using reasonable technical measures. Service providers are protected from liability when they comply in good faith with blocking orders and can recover their compliance costs from the copyright holder who sought the order, and they may temporarily suspend blocking for network maintenance or security purposes. This legislation amends federal copyright law to provide copyright owners with expanded enforcement tools against overseas piracy operations that harm U.S. intellectual property rights.
