Safe harbors for online services
If you run a website, app, or platform that hosts user content, the DMCA's safe harbors can shield you from money damages for users' infringement, but only if you meet the law's conditions. Those include designating an agent to receive notices through the Copyright Office's online directory and keeping the designation current, and adopting and reasonably implementing a policy for terminating repeat infringers, among other requirements. A service that knows of specific infringement, or is aware of facts making it apparent, has to act quickly to remove it. Losing the safe harbor does not mean automatic liability, but it removes an important protection.
Digital locks and copyright information
A separate part of the DMCA prohibits circumventing technological measures that control access to copyrighted works, and trafficking in tools designed for that purpose, though courts are divided on whether any link to infringement has to be shown. Exemptions for specific activities, such as certain repair and research uses, are set through a recurring rulemaking run by the Copyright Office and are revisited each cycle. Another provision addresses removing or falsifying copyright management information, such as author credits or watermarks, when done with the required knowledge or intent. These claims arise in disputes over software, games, streaming, and photographs whose credits were stripped.
Which side you are on
Most DMCA questions start with role. A platform owner needs its agent designation, repeat infringer policy, and notice-handling procedures reviewed. A rights holder may have takedown, circumvention, or management-information claims. A user whose content was removed may consider a counter-notice, which is made under penalty of perjury and can lead to a lawsuit. We work out which part of the law applies before anything is sent, and we keep a record of each notice, response, and date.
