Federal Trademark Dilution Claims

Dilución de marca: protección para marcas que el público general de los Estados Unidos reconoce.

Federal dilution law lets the owner of a famous mark stop uses that blur its distinctiveness or tarnish its reputation, even when no buyer is confused and the parties do not compete. The claim is reserved for marks widely recognized by the general consuming public of the United States, and money is available only for willful conduct. We help brand owners decide whether their mark clears that bar and build the proof.

What dilution protects

Dilution protects the famous mark itself, not just buyers

Most trademark claims ask one question: are buyers likely to be confused about who makes a product? A dilution claim asks a different one. It asks whether another company's use of a similar mark is likely to weaken the link between a famous mark and its owner, or to harm the famous mark's reputation. The claim exists because a few marks are so well known that copying them causes harm even when no one is fooled.

The federal claim is in 15 U.S.C. § 1125(c), as rewritten by the Trademark Dilution Revision Act of 2006 (TDRA). The owner of a famous mark that is distinctive, "inherently or through acquired distinctiveness," can stop another person's use that is likely to cause dilution by blurring or by tarnishment. The statute says this applies "regardless of the presence or absence of actual or likely confusion, of competition, or of actual economic injury."

That makes dilution a strong tool against uses that an infringement claim may not reach: a well-known fashion mark on a hardware product, a famous beverage name on an unrelated service, or a household brand placed on goods that cheapen it. The price of that reach is a very high entry bar. The mark must be famous to the general consuming public of the United States, and the plaintiff must prove it.

Susan J. Latham leads our dilution work, alongside her trademark, trade dress, and false advertising litigation. Robert H. Thornburg handles the Lanham Act counts usually pleaded with it.

A dilution count fits when

  • Your mark is recognized by ordinary U.S. consumers, not only by buyers in your industry
  • The other use is in unrelated goods or services, so confusion is hard to prove
  • The other use is unsavory or low-quality and links your brand to it
  • The other side began its use after your mark was already famous
  • You have national advertising, sales, and recognition evidence you can produce

The threshold

Fame means a household name across the United States

A mark is famous "if it is widely recognized by the general consuming public of the United States as a designation of source of the goods or services of the mark's owner" (§ 1125(c)(2)(A)). The court may consider all relevant factors, including these four.

01 · Advertising

Reach of advertising and publicity

The duration, extent, and geographic reach of advertising and publicity, whether by the owner or by third parties. Unsolicited national press counts.

§ 1125(c)(2)(A)(i)
02 · Sales

Volume and spread of sales

The amount, volume, and geographic extent of sales of goods or services offered under the mark. Sales concentrated in one region point away from national fame.

§ 1125(c)(2)(A)(ii)
03 · Recognition

Actual recognition

The extent of actual recognition of the mark, usually shown by a survey of the general public and by brand rankings and media references.

§ 1125(c)(2)(A)(iii)
04 · Registration

Federal registration

Whether the mark is registered on the principal register or under the 1881 or 1905 Acts. Registration helps, but it does not make a mark famous.

§ 1125(c)(2)(A)(iv)

Niche and regional fame do not count. Before 2006, the federal statute let courts judge recognition within the trading areas and channels of trade used by the mark's owner, and some courts accepted fame within a market niche. The TDRA replaced that with the "general consuming public" test. A mark well known to restaurant operators, to boaters, or to shoppers in South Florida is not famous for federal purposes unless ordinary consumers across the country also know it.

Florida federal courts apply the test strictly at the pleading stage. In GLD, LLC v. Gold Presidents, LLC, No. 20-21617-CIV-MORENO (S.D. Fla. Jan. 15, 2021), the court dismissed a federal dilution count over a luxury watch design because the complaint did not plead a prima facie case of fame, observing that dilution is reserved for truly famous marks such as Budweiser, Camel, and Barbie. The court dismissed the Florida dilution counts for the same reason.

Fame is proved mark by mark, and it must come first. The statute protects against uses that begin "after the owner's mark has become famous." In 2026 the Ninth Circuit held that the TDRA "does not permit borrowing fame from one senior mark to establish the fame of another," so a famous house mark does not make a secondary slogan or label famous (VIP Products, LLC v. Jack Daniel's Properties, Inc., No. 25-2027 (9th Cir. Aug. 4, 2026)). Unregistered trade dress carries a further burden: the owner must prove it is not functional and is famous as a whole, and separately from the fame of any registered marks it includes (§ 1125(c)(4)).

Who usually clears the bar

  • National consumer brands with years of mass-media advertising
  • Marks with high unaided recognition in general-population surveys
  • Brands that appear in national brand-value rankings and everyday press
  • Foreign brands with large, long-running U.S. sales and advertising, not only fame abroad

Fame in Europe or Latin America does not by itself establish U.S. fame. The statute looks at the U.S. consuming public.

Elements

What you must prove, and the evidence that proves it

Courts in the Southern District of Florida state the elements as: the mark is famous; the defendant adopted its mark after the mark became famous; the defendant's use is commercial and in commerce; and the use is likely to dilute the mark (GLD, quoting Brain Pharma, LLC v. Scalini, 858 F. Supp. 2d 1349 (S.D. Fla. 2012)). The statute adds that the mark must be distinctive.

ElementSourceHow it is provedTypical evidence
Famous and distinctive mark Threshold§ 1125(c)(1), (c)(2)(A)Recognition by the general consuming public of the United States as your source identifierNational advertising spend and reach, sales by state, general-population fame survey, unsolicited media, rankings, registrations

or likely dilution by tarnishment§ 1125(c)(2)(C)Association from similarity that is likely to harm the famous mark's reputationThe accused product and its context, a study of the accused use, evidence of the negative association
Willfulness (for money only) Remedies§ 1125(c)(5)First use in commerce after October 6, 2006, and willful intent to trade on recognition (blurring) or to harm reputation (tarnishment)Internal emails, design files, prior dealings, knowledge of your mark, a cease-and-desist letter and continued use

No proof of confusion, of competition between the parties, or of actual economic injury is required (§ 1125(c)(1)). We still plead confusion-based counts when the facts support them, because they do not depend on fame.

Two theories

Blurring weakens the link; tarnishment damages the reputation

A complaint can plead one theory or both. They are proved differently, and the willfulness needed for money differs too.

Dilution by blurringDilution by tarnishment
Statutory definitionAssociation from similarity "that impairs the distinctiveness of the famous mark"Association from similarity "that harms the reputation of the famous mark"
Core harmThe mark stops pointing to one source; many uses erode its uniqueness over timeThe mark is linked to something unwholesome, low quality, or offensive
How courts weigh itSix listed factors, plus any other relevant factorNo listed factors; the context of the accused use and evidence of reputational harm
Willfulness for moneyWillful intent "to trade on the recognition of the famous mark"Willful intent "to harm the reputation of the famous mark"
Key evidenceSimilarity, association surveys, intent, exclusivity of your useThe accused product in its real market setting; a study of that product

◆ marks rows where the two theories differ in substance.

The six blurring factors, § 1125(c)(2)(B)

1

Degree of similarity

How close the defendant's mark or trade name is to the famous mark. The statute does not require the marks to be identical or "substantially similar"; similarity is a factor to weigh.

§ 1125(c)(2)(B)(i)
2

Distinctiveness of the famous mark

The degree of inherent or acquired distinctiveness. Coined and arbitrary marks are easier to blur than marks built from common words.

§ 1125(c)(2)(B)(ii)
3

Substantially exclusive use

Whether the owner is engaging in substantially exclusive use. Many third-party uses of the same term suggest little distinctiveness left to protect, which makes policing records important.

§ 1125(c)(2)(B)(iii)
4

Degree of recognition

How well known the famous mark is. It overlaps with the fame evidence, but here the question is strength, not just whether the threshold is met.

§ 1125(c)(2)(B)(iv)
5

Intent to create an association

Whether the defendant meant to call the famous mark to mind. Names chosen to echo a famous brand, and marketing that invokes it, are typical proof.

§ 1125(c)(2)(B)(v)
6

Actual association

Any actual association between the two marks, usually shown by a survey asking what the accused mark brings to mind. Actual association is evidence, not a requirement.

§ 1125(c)(2)(B)(vi)

Tarnishment needs evidence about the accused use itself. In the 2026 VIP Products decision on the "Bad Spaniels" dog toy, the Ninth Circuit vacated a tarnishment injunction. It found no tarnishment on the face of the toy, and it rejected expert testimony that relied on general consumer-psychology research without any study of the accused product, calling the opinion "pure conjecture." The court also treated the toy's obvious parody as relevant to whether reputational harm was likely, even though parody used as a brand is not excluded from the statute. The decision binds courts in the Ninth Circuit, not the Eleventh, but it shows the kind of proof any court will expect.

How the standard changed

The claim requires likely dilution, not proof of actual harm

Today a plaintiff must show that the defendant's use is "likely to cause" dilution. It was not always so.

  1. 1995–2003Federal Trademark Dilution ActFirst federal dilution claim. Courts split over niche fame and over whether actual harm had to be shown.
  2. March 4, 2003Moseley v. V Secret CatalogueThe Supreme Court read the 1995 Act to require "a showing of actual dilution, rather than a likelihood of dilution."
  3. October 6, 2006TDRA enactedPub. L. 109-312 adopts the "likely to cause" standard, the general-public fame test, the blurring factors, and the exclusions.
  4. June 8, 2023Jack Daniel's v. VIP ProductsA unanimous Court holds that the noncommercial-use exclusion does not shield parody used as a source identifier.
  5. August 4, 2026Ninth Circuit on remandTarnishment injunction vacated for lack of proof; fame cannot be borrowed from one mark for another.

The TDRA replaced the actual-dilution rule of Moseley v. V Secret Catalogue, Inc., 537 U.S. 418 (2003), with the current text, which grants an injunction against a use "that is likely to cause dilution by blurring or dilution by tarnishment." The owner does not have to wait for measurable damage to its brand. But "likely" still has to be proved with evidence, and courts look closely at surveys and expert opinions offered to show it.

What the defendant will argue

Three statutory exclusions, and where they stop

Section 1125(c)(3) lists uses that "shall not be actionable as dilution." Expect the defendant to raise them. We assess each one before filing.

§ 1125(c)(3)(A)Fair use

Any fair use, including nominative or descriptive fair use, "other than as a designation of source for the person's own goods or services," including comparative advertising and "identifying and parodying, criticizing, or commenting upon" the famous mark owner or its goods or services.

§ 1125(c)(3)(B)News reporting

"All forms of news reporting and news commentary."

§ 1125(c)(3)(C)Noncommercial use

"Any noncommercial use of a mark." The reach of this exclusion is not fully settled.

The limitUse as a brand

The fair-use exclusion does not apply when the defendant uses the famous mark, or a parody of it, as its own source identifier.

Jack Daniel's Properties, Inc. v. VIP Products LLC (2023). VIP sold a dog toy shaped like a Jack Daniel's bottle, called "Bad Spaniels," and used that name and design as its own trademark. The Ninth Circuit had held the toy exempt from dilution liability under the noncommercial-use exclusion because it parodied the whiskey brand. The Supreme Court unanimously disagreed. Reading the statute as a whole, it held that the noncommercial exclusion "does not shield parody or other commentary when its use of a mark is similarly source-identifying." Otherwise, the Court explained, the noncommercial exclusion would swallow Congress's choice to deny the fair-use exclusion to parodies used as a brand.

The Court did not decide how far the noncommercial-use exclusion reaches in other settings. And as the 2026 remand decision shows, parody that falls outside the exclusions can still matter to whether tarnishment is likely.

For the defendant's full playbook, see Trademark Dilution Defense.

How we prepare for the exclusions

  • Document how the defendant uses the mark: as its brand, in its name, on labels, in domains
  • Separate commercial product sales from commentary, reviews, and news
  • For comparative ads, show where the use goes beyond identifying your product
  • For parody, collect evidence that the parody is the defendant's own trademark
  • Plead infringement and false endorsement counts that do not depend on the exclusions
Remedies

An injunction is the main remedy; money needs two extra facts

Any owner who proves dilution may seek an injunction. Money is available only if the accused use began after the TDRA took effect and the defendant acted willfully.

Always available on proof of dilution

15 U.S.C. §§ 1116(a), 1125(c)(1)

  • Preliminary and permanent injunctions, with a rebuttable presumption of irreparable harm once you show likely success (preliminary relief) or a violation (permanent relief); the presumption was added in 2020 and expressly covers violations of § 1125(c)
  • Court-ordered cancellation of a defendant's federal registration in the same action (§ 1119)

Only if both conditions in § 1125(c)(5) are met

First use after October 6, 2006, and willful intent

  • Defendant's profits, damages, and costs under § 1117(a), subject to the court's discretion and the principles of equity
  • Attorney's fees "in exceptional cases" (§ 1117(a))
  • Delivery and destruction of labels, packaging, and advertising under § 1118
Oct. 6, 2006Accused use must have begun after this date for money
WillfulIntent to trade on recognition, or to harm reputation
§ 1117(a)Profits, damages, costs; fees in exceptional cases
§ 1116(a)Rebuttable presumption of irreparable harm

Decision guide

Four questions that decide whether money is on the table

We answer these before deciding how much weight to put on the dilution count.

Q1Is the mark famous to the general U.S. public, and can you prove it?

If not, the federal dilution count is likely to be dismissed or lost. Consider Florida dilution, infringement, and unfair competition instead.

Q2When did the defendant first use its mark in commerce?

If before your mark became famous, there is no dilution claim. If before October 6, 2006, the claim can support an injunction, but not money under § 1125(c)(5).

Q3Is there evidence of willful intent?

For blurring, intent to trade on the mark's recognition; for tarnishment, intent to harm its reputation. Copying, references to your brand, and continued use after notice are the usual proof.

Q4Does the defendant hold a federal registration for its mark?

A valid federal registration does not bar a federal dilution claim, but it is a complete bar to state-law dilution claims about that mark (§ 1125(c)(6)). Plan a cancellation count if the Florida claim matters.

Federal and state claims

A federal registration is a complete bar to state dilution claims

Under § 1125(c)(6), a person's valid registration on the principal register (or under the 1881 or 1905 Acts) is "a complete bar" to an action against that person, with respect to that mark, brought under state common law or a state statute that seeks to prevent dilution by blurring or tarnishment, or that claims harm to the distinctiveness or reputation of a mark, label, or form of advertisement.

The bar protects defendants that hold federal registrations. It does not stop the federal dilution claim, and it does not apply to defendants without a registration. When the defendant is registered, the usual answer is to challenge the registration:

  • In the lawsuit. A court "may determine the right to registration" and order cancellation in any action involving a registered mark (§ 1119).
  • At the TTAB, within five years. A petition to cancel may be filed by anyone who believes it will be damaged, "including as a result of a likelihood of dilution by blurring or dilution by tarnishment," within five years from the registration date (§ 1064(1)). Dilution is not among the grounds listed for older registrations.
  • Before registration. Dilution is also a ground to oppose an application within 30 days after publication (§ 1063(a)). Watching the register is cheaper than suing later.

Before filing, we check

  • Whether the defendant owns a federal registration for the accused mark, and its registration date
  • Whether it is inside the five-year window for a dilution-based cancellation
  • Other grounds to cancel an older registration, such as abandonment or fraud
  • Pending applications that can still be opposed
  • Whether a Florida dilution count survives the bar
Evidence

How fame and dilution are proved

Fame is a fact question, and the plaintiff carries the burden. Start collecting before the complaint is filed, because a complaint that only says "famous" is vulnerable to dismissal.

Fame evidence checklist

  • Advertising spend by year and medium, with national reach figures
  • Third-party publicity: national press, broadcast, social media coverage you did not pay for
  • Sales and units by year, broken down by state to show national scope
  • A general-population fame survey run by a qualified expert
  • Brand rankings, awards, and appearances in popular culture
  • Federal registrations, with dates, and evidence of continuous use
  • Dated proof that fame existed before the defendant's first use
  • Enforcement records showing substantially exclusive use

Dilution and willfulness evidence

  • The accused mark, product, packaging, and listings, captured with dates
  • The defendant's first-use date from USPTO filings, web archives, and discovery
  • An association survey of the accused mark (blurring)
  • A study of the accused product in its real market context (tarnishment)
  • Internal documents on how and why the name was chosen
  • Your demand letter and the defendant's continued use after receiving it
  • A preservation notice so the defendant's records survive

Surveys are not required by statute, but fame and association are hard to prove without them. The survey must test the right universe: the general U.S. consuming public for fame, not your customers. A survey of buyers in one industry may support niche fame, which federal law no longer recognizes.

The lawsuit

Lifecycle of a federal dilution case

Dilution is usually one count in a broader Lanham Act complaint, so it follows the same path. The differences are in the evidence, which is heavier on fame.

  1. Pre-suitFame audit and letterAssemble fame proof, fix the defendant's first-use date, check its registrations, and decide on a letter.
  2. FilingComplaintPlead specific fame facts, both dilution theories where supported, and the related counts.
  3. EarlyTRO or preliminary injunctionShow likely success and use the § 1116(a) presumption of irreparable harm. Delay weakens the request.
  4. DiscoveryRule 26 and discoveryInitial disclosures, then discovery into first use, intent, and the defendant's sales.
  5. ExpertsSurveys and expert reportsFame survey of the general public; association or reputational studies of the accused use.
  6. MotionsSummary judgmentFame is often decided here. Weak fame evidence ends the count.
  7. TrialTrial, remedies, appealInjunction, profits or damages if willful, fees in exceptional cases; appeal to the Eleventh Circuit.
Common mistakes

Five most common mistakes in dilution claims

1

Pleading fame without facts

A conclusory allegation that the mark is "famous" invites a motion to dismiss. Florida federal courts have dismissed dilution counts for this reason.

§ 1125(c)(2)(A)
Lesson

Plead advertising, sales, recognition, and registration facts, with national scope.

2

Relying on industry or regional fame

Recognition among trade buyers, or within Florida, is niche fame. It does not meet the federal test.

General consuming public
Lesson

Use the Florida claim for state fame and keep infringement counts in the case.

3

Ignoring the first-use date

If the defendant started before your mark became famous, there is no claim. If it started before October 6, 2006, there is no money.

§ 1125(c)(1), (c)(5)
Lesson

Fix the defendant's first-use date before filing.

4

Borrowing fame across marks

A famous house mark does not make a slogan, label, or product design famous. Each asserted mark must be proved.

VIP Products (9th Cir. 2026)
Lesson

Assert the marks you can prove, and build separate evidence for each.

5

Generic expert evidence on tarnishment

Testimony that relies on general consumer psychology without studying the accused product may be given no weight.

Tarnishment proof
Lesson

Test the actual accused product in its real market setting.

Questions

Frequently asked questions

Do I have to prove consumers are confused to win a dilution claim?

No. Section 1125(c)(1) grants relief "regardless of the presence or absence of actual or likely confusion, of competition, or of actual economic injury." You must instead prove the mark is famous and that the defendant's use is likely to cause dilution by blurring or tarnishment.

My brand is very well known in Florida. Can I bring a federal dilution claim?

Only if it is also widely recognized by the general consuming public of the United States. Regional or industry fame does not meet the federal test. Florida's statute protects marks famous in Florida; see Florida Trademark Dilution Claims.

Can a foreign brand rely on its fame in Europe or Latin America?

Not by itself. The statute measures recognition by the U.S. consuming public, through U.S. advertising, sales, and recognition evidence. Fame abroad can be relevant background, but U.S. evidence decides the question.

Can I recover money for dilution?

Only if the defendant first used its mark in commerce after October 6, 2006, and acted willfully: intending to trade on the mark's recognition (blurring) or to harm its reputation (tarnishment). Then the remedies of §§ 1117(a) and 1118 are available at the court's discretion. Otherwise relief is an injunction.

Is parody a defense to dilution?

Parody that identifies and comments on the famous mark is excluded, but not when the defendant uses the parody as its own brand. In Jack Daniel's v. VIP Products (2023), the Supreme Court held the noncommercial-use exclusion does not shield source-identifying parody. Parody can still bear on whether tarnishment is likely.

Does it matter that the defendant has its own federal registration?

It does not bar a federal dilution claim, but a valid federal registration is a complete bar to state-law dilution claims about that mark under § 1125(c)(6). A court can order cancellation of the registration under § 1119, and a TTAB petition based on dilution must be filed within five years of registration.

Do I need a survey?

The statute does not require one, but proving fame among the general public and actual association usually depends on survey evidence. In 2026 the Ninth Circuit rejected a tarnishment expert's opinion as "pure conjecture" because he had not studied the accused product.

Can unregistered trade dress be diluted?

Yes, but the owner must prove the trade dress, taken as a whole, is not functional and is famous, and, if it includes registered marks, that the unregistered matter is famous apart from them (§ 1125(c)(4)). See Trade Dress Infringement Lawsuits.
