Copyright notices explained: ISP letters, DMCA takedowns and AI-content claims

A copyright notice can arrive in several forms: an email forwarded by your internet provider, a message that a platform removed your post, a letter from a law firm, or a claim that something you made was generated by AI. Each works differently, carries different risks and has a different response. This section explains them one at a time.

If you have a notice in front of you, the first section below helps you work out which kind it is. Everything here is general information about US law. If you have been served with court papers, talk to a lawyer licensed where you live.

02Notices from your internet provider

Rights holders monitor file sharing networks and report the IP addresses they see. Your provider matches the address to your account and forwards the complaint. Under section 512(i) of the Copyright Act, providers must have a policy to terminate repeat infringers in appropriate circumstances, so further notices can lead to required acknowledgments, suspension or termination. The notice does not reveal your name to the rights holder; that generally takes a court order.

Between 2013 and 2017 these notices ran through a shared program, the Copyright Alert System. Today each provider uses its own policy. Our archive explains why the six strikes program ended, and our guide to what to do after a notice from your internet provider covers the first week, repeat infringer policies and settlement letters.

03DMCA takedowns and counter-notices

A DMCA takedown asks a website or platform to remove material that infringes someone's copyright. The law lists six things a valid notice must contain, including a statement under penalty of perjury. Platforms usually remove the material quickly and tell the poster. The poster can send a counter-notice, and the platform then restores the material in 10 to 14 business days unless the sender files a lawsuit. The US Copyright Office's section 512 resource page summarizes these steps.

Our full guide explains how to send, answer or counter a DMCA takedown notice, including false notices and platform strike systems.

04AI-content claims

AI has created two new kinds of claim. Sometimes an AI system produces output that copies an existing work, and someone posts it. Sometimes a person's own work is removed, rejected or flagged because someone believes a machine made it. The first can often be handled with an ordinary takedown. The second usually depends on a platform's or school's own rules, and is answered with evidence of how you made the work.

Our page on takedowns when AI copies your work or your work is called AI-made covers both.

05What not to do

  • Do not ignore court papers. Lawsuits have strict deadlines, and missing one can lead to a default judgment.
  • Do not pay a settlement demand on the spot. Confirm who sent it and whether any lawsuit exists.
  • Do not send a counter-notice you cannot stand behind. It is a sworn statement and shares your contact details with the sender.
  • Do not send a takedown for something you merely dislike. Criticism and parody may be fair use, and false notices carry liability.
  • Do not reply to a rights holder in anger. Keep any response short and factual, and keep copies.
  • Do not delete your records. Drafts, files and messages may be your best evidence later.

07Questions people ask

Is a copyright notice the same as being sued?

No. Provider notices and platform takedowns are complaints, not lawsuits. A lawsuit begins when someone files in court, and you would be formally served with papers.

Can I ignore a copyright notice?

You can choose not to respond to many notices, but ignoring them has costs: repeated provider notices can affect your internet service, and repeated takedowns can cost you a platform account.
