Copyright Statute of Limitations

One of the most important things to understand about copyright law: you don't have forever to file a lawsuit. The statute of limitations sets a deadline, and missing it can bar your claim entirely — even if your work was clearly stolen.

The Three-Year Rule

Under 17 U.S.C. Section 507(b), civil copyright claims must be filed within three years of the claim accruing. But when does a claim "accrue"? That question has been the subject of significant litigation.

The Discovery Rule

The Supreme Court recently clarified that a copyright claim accrues when the plaintiff discovers — or with reasonable diligence should have discovered — the infringement. This is called the "discovery rule." It means the clock starts ticking when you find out your work was stolen, not necessarily when the theft occurred.

What This Means for AI Training Cases

For creators discovering that their work was included in AI training datasets, the statute of limitations is a critical concern. Many training datasets were created years ago. If the discovery rule applies, the clock starts when you learn your work was in the dataset — but you need to act promptly once you know.

Register Early, Register Often

Copyright registration before infringement (or within three months of publication) is essential if you want to recover statutory damages and attorney's fees. Registration is not required for ownership, but it IS required before filing a lawsuit for U.S. works. Register your work now — even for old work — to preserve rights for ongoing or future infringement.

Practical Steps

1. Register your work with the U.S. Copyright Office if you haven't already
2. Document the date of discovery — this could be the most important date in your case
3. Act promptly — don't wait to consult an attorney or explore your options
4. Preserve all evidence — original files, timestamps, correspondence
