The DMCA Anti-Circumvention Provisions: Section 1201, Digital Locks, and the Triennial Exemptions
Section 1201 of the Copyright Act makes it unlawful to break a digital lock on a copyrighted work, and unlawful to sell tools that do the breaking, even when the underlying use would be perfectly lawful. That decoupling of circumvention from infringement is what makes section 1201 both powerful and controversial, and it catches security researchers, repair shops, tinkerers, and competitors far more often than it catches pirates. This article explains the structure of the statute, the difference between access controls and copy controls and why it matters, the two trafficking bans, the seven permanent exemptions, and the triennial rulemaking through which the Librarian of Congress grants temporary exemptions for uses like jailbreaking phones, repairing tractors, and preserving video games. It works through the leading appellate decisions, including Corley, Chamberlain, Lexmark, and MDY v. Blizzard, and explains the circuit split over whether a section 1201 claim requires a nexus to infringement. It closes with compliance guidance for device makers, software vendors, researchers, and repair businesses, plus a worked example, an FAQ, and related reading.
