The law, plainly

What is § 512(f)?

Section 512(f) is the reason this site keeps telling you which cases we will not take. It makes a knowingly false notice actionable against the person who sent it — and when an agent signs, that is the agent.

What the provision says

Section 512(f) makes any person who knowingly materially misrepresents that material is infringing — or that it was removed by mistake or misidentification — liable for damages, including costs and attorney’s fees, incurred by the alleged infringer, the copyright owner or its agent, or the service provider.

Three things in that sentence matter operationally. It says any person, which reaches agents and services, not only rights holders. It covers both directions, so a false counter-notice is equally exposed. And it includes attorney’s fees, which is what makes it worth someone’s while to bring.

The bar: knowingly and materially

The standard is not strict liability and it is not negligence. Courts have generally required subjective bad faith — actual knowledge that the representation was false — rather than an objective “should have known”.

Rossi v. MPAA (9th Cir. 2004) established that the good-faith belief is measured subjectively, so a sender who genuinely but unreasonably believed infringement was occurring is generally not liable. That is a meaningful protection for honest claimants.

Online Policy Group v. Diebold (N.D. Cal. 2004) went the other way on the facts: a company that used notices to suppress embarrassing internal emails, where no reasonable copyright holder could have believed the postings were infringing, was held liable. The damages awarded were modest; the precedent was not.

Lenz, and the fair-use duty

Lenz v. Universal Music Corp. (9th Cir. 2015) is the case that changed day-to-day practice. A mother posted a short video of her child dancing to a song; the rights holder sent a notice; the court held that a copyright holder must consider whether the use is a fair use before sending a notification.

The reasoning follows from the words of the statute. Element (v) requires a good-faith belief that the use is not authorised by the owner, its agent, or the law. Fair use is authorised by law. A sender who never asked the question cannot honestly make the statement.

The duty is to consider, not to be correct. The court was explicit that a holder who forms a subjective good-faith belief after considering fair use is protected even if a court would later disagree.

Which makes it an easy bar to clear and a careless one to miss

Walking four factors and writing down the answer takes a few minutes. Not doing it is the exposure, and it is exposure you took on for no benefit at all.

What we do about it

Because we sign as agent, this provision is pointed at us as well as at our clients. That shapes the product rather than just the paperwork.

  • Every URL carries a written fair-use consideration before it can be approved. The software refuses the approval without one — it is not a tick box.
  • Every URL carries a written record of how ownership was established, with a date and a source.
  • Every match is re-fetched and confirmed word for word on the live page before it is even shown to a client, so nothing is filed on a stale search result.
  • Cases that fail the fair-use check are declined in writing, with the reason, and there is no charge.
  • Notices are not generated at all when a required element is missing, rather than generated with a gap.

None of that is generosity. A service that files everything gets one good quarter and then a § 512(f) claim with attorney’s fees attached.

How this shapes a responsible filing process

Section 512(f) is not usually a reason to avoid filing. It is a reason to be able to show what you checked before you did.

Confirm ownership before anything else
Who created the work, under what arrangement, and is there a written assignment if someone else made it. A notice over material you do not own is the clearest way to find out how 512(f) works.
Look at the copy yourself
Automated matching is a way of finding candidates, not a conclusion. A human should open the page and confirm the material is actually there before a notice goes out.
Consider fair use, and write down the consideration
Lenz requires it. The record of having thought about it is as important as the conclusion, because the question in litigation is what you believed at the time.
Keep what you relied on
The archive link, the screenshot, the comparison. If the claim is ever questioned, the contemporaneous file is the answer.
Do not use a notice for something it is not for
Competitive annoyance, a contract dispute, unwanted criticism. Those are real problems with other remedies, and Diebold is what happens when a copyright notice is used for them.

A process that does these five things produces notices that are both more likely to succeed and far harder to characterise as knowing misrepresentation. The two goals point the same way.

What the standard actually requires

The statutory words are “knowingly materially misrepresents”, and courts have read them narrowly. Rossi v. Motion Picture Association of America established that the test is subjective: liability attaches to actual knowledge of misrepresentation, not to a claim that merely turns out to be wrong. An honest mistake, even an unreasonable one, generally does not meet it.

That makes successful 512(f) claims uncommon. It does not make the section ornamental. Lenz v. Universal added that a copyright holder must consider fair use before sending a notice, and that failing to do so can itself support a 512(f) claim. Online Policy Group v. Diebold produced liability where notices were sent over material the sender knew was not infringing, to suppress embarrassing documents rather than to protect a work.

The pattern across the cases is that the risk is not in being wrong. It is in not having looked, or in using the notice for something other than what it is for.

Questions

What people ask next

  • Can I be sued for an honest mistake?

    The standard is subjective bad faith, so an honest mistake is generally not actionable. Rossi protects a sender who genuinely believed infringement was occurring even if that belief was unreasonable. Honest and careful is better than honest alone.

  • Does § 512(f) apply to automated notices?

    It applies to any person who knowingly materially misrepresents. Volume filing without human review is exactly the practice that invites an argument that no genuine belief was formed about any individual notice, which is one reason we do not file automatically from scanner output.

  • How much are § 512(f) damages?

    The provision covers damages, costs and attorney's fees incurred by the injured party. Reported awards have often been modest, but legal fees in a defended case are not, and the fee-shifting is the real teeth of the provision.

  • Does this apply outside the Ninth Circuit?

    § 512(f) is federal and applies everywhere. Lenz is Ninth Circuit authority, so its fair-use holding binds there and is persuasive elsewhere. Given that a great many relevant service providers are in California, treating it as the operating rule is the prudent default.
