Summary. Dilution is the trademark claim that does not require confusion. It protects a small class of genuinely famous marks against uses that whittle away their distinctiveness or drag their reputation through the mud, even when no consumer is deceived about anything. This article explains the Trademark Dilution Revision Act of 2006, why Congress passed it to overrule the Supreme Court's actual-dilution requirement in Moseley v. V Secret Catalogue, and what a plaintiff must now prove: fame among the general consuming public of the United States, distinctiveness, use in commerce beginning after the mark became famous, and a likelihood of blurring or tarnishment. It works through the six statutory blurring factors with case illustrations, explains the three statutory exclusions and how the Supreme Court narrowed the parody safe harbor in Jack Daniel's Properties, Inc. v. VIP Products LLC, and covers state antidilution statutes, TTAB dilution claims, remedies, and evidence. It closes with brand-owner and defense strategy, a worked example, an FAQ, and related reading.

Imagine a hardware store called Kodak Plumbing Supply. Nobody would think Eastman Kodak had gotten into pipe fittings. No customer would be confused about anything. And yet something is lost: the next time you hear "Kodak," a small piece of your mind now goes to elbow joints instead of film. Do that a hundred times, across a hundred industries, and the word stops meaning one thing.

That is the injury dilution law addresses. Frank Schechter described it in 1927 as "the gradual whittling away or dispersion of the identity and hold upon the public mind of the mark or name by its use upon non-competing goods," The Rational Basis of Trademark Protection, 40 Harv. L. Rev. 813 (1927), and the phrase still appears in briefs today.

Dilution is also the most misused claim in trademark practice. It gets pleaded reflexively in cases where the mark is not remotely famous, and it gets dismissed just as reflexively. Understanding when it actually works, and when it is a waste of a count, is worth real money.

The short answer

Under 15 U.S.C. § 1125(c), the owner of a famous and distinctive mark may enjoin another's use in commerce of a mark or trade name that began after the plaintiff's mark became famous and that is likely to cause dilution by blurring or dilution by tarnishment, regardless of the presence or absence of actual or likely confusion, competition, or actual economic injury.

Five elements. The first one kills most cases:

  1. The plaintiff's mark is famous, meaning "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).
  2. The mark is distinctive, either inherently or through acquired distinctiveness.
  3. The defendant began using its mark after the plaintiff's became famous.
  4. The defendant's use is in commerce and is as a mark or trade name (this last point sharpened considerably after Jack Daniel's).
  5. The use is likely to cause dilution by blurring or tarnishment.

Three statutory exclusions then apply: certain fair uses (including nominative and descriptive fair use, comparative advertising, and parody), news reporting and commentary, and any noncommercial use. § 1125(c)(3).

Remedies are ordinarily injunctive only, unless the defendant willfully intended to trade on the plaintiff's reputation (for blurring) or to harm the mark's reputation (for tarnishment), in which case the full monetary remedies of §§ 1117(a), 1118 become available. § 1125(c)(5).

Part I: How we got here

The pre-federal era

Massachusetts enacted the first state antidilution statute in 1947, and roughly half the states eventually followed, generally along the lines of the Model State Trademark Bill. State claims typically required a "distinctive" mark and a "likelihood of injury to business reputation or of dilution of the distinctive quality of a mark," and famously did not require competition or confusion. Some state courts read the fame requirement loosely, which produced a body of case law protecting regionally known marks that no federal court would call famous.

The 1995 FTDA and the Moseley problem

Congress federalized dilution in the Federal Trademark Dilution Act of 1995, adding § 43(c) to the Lanham Act. The statute created a cause of action against uses that "cause dilution of the distinctive quality" of a famous mark. Circuits split immediately over whether "causes dilution" required proof of actual dilution or only a likelihood of it. The Fourth Circuit demanded actual dilution in Ringling Bros.-Barnum & Bailey Combined Shows, Inc. v. Utah Division of Travel Development, 170 F.3d 449 (4th Cir. 1999) ("THE GREATEST SHOW ON EARTH" against Utah's "THE GREATEST SNOW ON EARTH"). The Second Circuit took a more permissive view in Nabisco, Inc. v. PF Brands, Inc., 191 F.3d 208 (2d Cir. 1999) (Pepperidge Farm's Goldfish crackers).

The Supreme Court resolved the split the hard way. In Moseley v. V Secret Catalogue, Inc., 537 U.S. 418 (2003), Victoria's Secret sued a small Elizabethtown, Kentucky adult novelty shop called "Victor's Little Secret." The Court held unanimously that the FTDA required proof of actual dilution, not merely a likelihood of it. Justice Stevens acknowledged that "the mere fact that consumers mentally associate the junior user's mark with a famous mark is not sufficient to establish actionable dilution," and that direct evidence would rarely be necessary where the marks were identical, but the holding made the claim nearly unprovable in the ordinary case. How, exactly, does one prove that a word has become marginally less distinctive?

The TDRA fixes it

Congress responded with the Trademark Dilution Revision Act of 2006, Pub. L. No. 109-312, which rewrote § 43(c) from the ground up. The TDRA:

  • Replaced actual dilution with likelihood of dilution, expressly overruling Moseley on that point.
  • Defined fame narrowly and nationally, eliminating "niche fame."
  • Codified blurring and tarnishment as the two theories, with six enumerated blurring factors.
  • Extended protection to marks that are famous through acquired distinctiveness, not only inherently distinctive marks (resolving another circuit split).
  • Wrote the three exclusions into the statute.
  • Limited monetary relief to cases of willful intent.

On remand after the TDRA, the Sixth Circuit found for Victoria's Secret in V Secret Catalogue, Inc. v. Moseley, 605 F.3d 382 (6th Cir. 2010), holding that a new mark's semantic association with sex and a famous mark selling lingerie created a presumption of tarnishment that the defendants had failed to rebut. Judge Karen Nelson Moore dissented on the burden-shifting point, and her dissent remains the best statement of the defense position on tarnishment.

Part II: Fame — the element that decides everything

The statutory standard

"[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).

Read each phrase:

  • "Widely recognized" means what it says. Substantial market share in an industry is not enough.
  • "The general consuming public of the United States" is the killer. This is a household-name standard. Fame among plumbers, radiologists, network engineers, or luxury handbag buyers is not fame under the TDRA. Congress deliberately abolished the "niche fame" doctrine that some courts had applied under the FTDA.
  • "As a designation of source" means renown as a brand, not as a phrase, a person, or a cultural artifact.

The statute lists four nonexclusive factors: (i) the duration, extent, and geographic reach of advertising and publicity; (ii) the amount, volume, and geographic extent of sales; (iii) the extent of actual recognition; and (iv) whether the mark is federally registered on the Principal Register.

What courts have done with it

Coach Services, Inc. v. Triumph Learning LLC, 668 F.3d 1356 (Fed. Cir. 2012), is the essential case. Coach, the handbag company, opposed registration of COACH for educational test-preparation materials. The Federal Circuit affirmed the TTAB's rejection of the dilution claim because Coach had not proved fame for dilution purposes, notwithstanding substantial sales and advertising. The court underscored that "fame for dilution requires a more stringent showing" than fame for likelihood of confusion, and that the standard is "an either/or proposition: it either exists or does not." Sales figures and advertising expenditures alone, without context showing public recognition, were insufficient.

That is the single most useful holding for defense counsel. Fame is binary, the bar is very high, and raw spending is not proof.

Marks that courts have found famous include NIKE, VICTORIA'S SECRET, VISA, STARBUCKS, LOUIS VUITTON, AUDI, NASDAQ, and similar household names. Marks found not famous include a long list of substantial, successful, regionally or industrially prominent brands that simply are not household words.

Timing

The junior user's use must have begun after the senior mark became famous. In practice this requires the plaintiff to prove when it became famous, a question most brand owners have never thought about and few can document. Marketing archives, media coverage, and any historical survey data become critical. Where the defendant can show it adopted its mark in 2004 and the plaintiff cannot prove household-name status before 2011, the claim fails on timing alone.

Part III: Dilution by blurring

The definition and the six factors

"[D]ilution by blurring is association arising from the similarity between a mark or trade name and a famous mark that impairs the distinctiveness of the famous mark." § 1125(c)(2)(B).

Two components: an association arising from similarity, and impairment of distinctiveness. Both are required. Moseley had made the same point about mere association, and although the TDRA overruled the actual-dilution holding, courts continue to insist that association alone is not enough. The Second Circuit made this explicit in Starbucks Corp. v. Wolfe's Borough Coffee, Inc., 736 F.3d 198 (2d Cir. 2013), the long-running "Charbucks" litigation, where it affirmed judgment for the defendant despite Starbucks's undisputed fame and a survey showing that some consumers associated "Charbucks" with Starbucks.

The statute lists six nonexclusive factors:

(i) The degree of similarity between the mark and the famous mark. Not identity, but similarity is heavily weighted. In Starbucks, the Second Circuit approved the district court's conclusion that the marks were only minimally similar because the defendant used "Mister Charbucks" and "Charbucks Blend" in packaging that emphasized its own house brand, Black Bear. The lesson for defendants: house-mark prominence and contextual presentation matter.

(ii) The degree of inherent or acquired distinctiveness of the famous mark. Coined marks (KODAK, EXXON, VERIZON) are the paradigm dilution plaintiffs. Descriptive marks with acquired distinctiveness may qualify but are weaker.

(iii) The extent to which the owner is engaging in substantially exclusive use. A crowded field is fatal. If forty companies use variations of the mark and the owner has tolerated them, the mark's distinctiveness has already been dispersed by the owner's own inaction. Policing records are therefore evidence, which is one more reason to run a real watch program. See Brand Protection Online.

(iv) The degree of recognition of the famous mark. Overlaps with fame but is scored again here.

(v) Whether the user intended to create an association with the famous mark. Intent is not required, but evidence of it is powerful, and it also unlocks monetary remedies under § 1125(c)(5) if the intent rises to willfulness.

(vi) Any actual association between the mark and the famous mark. This is where survey evidence lives. Note the trap illustrated by Starbucks: a survey showing association may satisfy factor (vi) and still leave the plaintiff short of proving impairment.

Similarity: how close is close enough?

Visa International Service Association v. JSL Corp., 610 F.3d 1088 (9th Cir. 2010), is the cleanest blurring win in the case law. JSL operated "eVisa," a multilingual education and job-listing service. Judge Kozinski's opinion explains the theory better than any treatise passage: VISA is an ordinary English word that the credit card company has, through enormous effort, made into a source identifier that consumers no longer parse as "an endorsement on a passport." A second commercial user of the same word "would fill the void with its own new meaning," and the singular association would be lost. Summary judgment for Visa affirmed.

Compare Levi Strauss & Co. v. Abercrombie & Fitch Trading Co., 633 F.3d 1158 (9th Cir. 2011), where the Ninth Circuit held that the TDRA does not require the marks to be identical or nearly identical; "similarity" is one factor, not a threshold. That corrected an earlier line of authority and matters in trade dress cases where the accused design is evocative rather than identical. For the trade dress context see The Intricate World of Trade Dress Protection.

Part IV: Dilution by tarnishment

"[D]ilution by tarnishment is association arising from the similarity between a mark or trade name and a famous mark that harms the reputation of the famous mark." § 1125(c)(2)(C).

Tarnishment is easier to describe than to prove. The paradigm is the use of a famous mark in connection with sex, drugs, illegality, or shoddy goods, such that consumers' positive associations are contaminated. V Secret Catalogue v. Moseley on remand is the leading modern application, and it went further than most: the Sixth Circuit held that when a junior mark associates a famous mark with sex-related products, there is an inference of tarnishment that the junior user must rebut.

Practical points:

  • Quality alone rarely tarnishes. Courts have generally rejected the theory that inferior goods automatically tarnish, absent an association that actually degrades the mark's reputation.
  • Unsavory context is the core. Adult content, illegal drugs, and criminal activity are the recurring fact patterns.
  • Political and social commentary is largely off limits to the claim, both because of the noncommercial-use exclusion and because of the First Amendment concerns that led some courts to be skeptical of tarnishment as a doctrine at all.
  • Registration cannot be refused on tarnishment grounds involving disparagement, following Matal v. Tam, 582 U.S. 218 (2017), and Iancu v. Brunetti, 588 U.S. 388 (2019). Those cases concerned registration bars, not dilution liability, but they reflect a judicial mood that shapes how tarnishment arguments land. See The Washington Redskins Trademark Troubles.

Part V: The three exclusions, and what Jack Daniel's did to them

Section 1125(c)(3) excludes three categories from dilution liability:

(A) Any fair use, including nominative or descriptive fair use, or facilitation of such fair use, of a famous mark by another person other than as a designation of source for the person's own goods or services, including use in connection with (i) advertising or promotion that permits consumers to compare goods or services, or (ii) identifying and parodying, criticizing, or commenting upon the famous mark owner or its goods or services.

(B) All forms of news reporting and news commentary.

(C) Any noncommercial use of a mark.

The parenthetical everyone missed

Look again at (A): the exclusion applies to fair use "other than as a designation of source for the person's own goods or services." That qualifier is the whole ballgame, and for years many practitioners read past it.

In Jack Daniel's Properties, Inc. v. VIP Products LLC, 599 U.S. 140 (2023), the Supreme Court gave it teeth. VIP sold a squeaky dog toy shaped like a Jack Daniel's bottle, labeled "Bad Spaniels," with jokes substituted for the label copy ("Old No. 2 on your Tennessee Carpet"). VIP had won below on two theories: that the Rogers v. Grimaldi, 875 F.2d 994 (2d Cir. 1989), test for expressive works shielded it from the infringement claim, and that the noncommercial-use exclusion shielded it from the dilution claim.

The Supreme Court reversed unanimously on both.

On infringement, the Court held that Rogers has no application when the accused party uses the challenged matter "as a designation of source for the infringer's own goods." VIP used "Bad Spaniels" as a trademark for its dog toy, so the ordinary likelihood-of-confusion analysis governs, with the parodic character relevant to that analysis rather than a threshold filter.

On dilution, the Court held that VIP could not invoke the noncommercial-use exclusion in § 1125(c)(3)(C). The reasoning is structural and elegant: exclusion (A) already carves out parody, criticism, and commentary, but only when the use is not as a designation of source. If exclusion (C) protected every parodic use, including source-identifying ones, exclusion (A)'s careful qualifier would be superfluous. Justice Kagan wrote that the noncommercial-use exclusion "does not include, and thus does not exclude from liability, every parody or humorous commentary."

What survives

Parody remains alive, but its home has moved:

  • Parody that does not function as a source identifier (a comedy sketch, a critical article, a protest poster, an editorial cartoon) remains protected by exclusions (A), (B), and (C).
  • Parody that functions as a brand for the parodist's own goods must survive the ordinary confusion analysis, and, on the dilution side, must contend with blurring and tarnishment on the merits.
  • The successful parody defendant now wins on the factors, not on a threshold. Louis Vuitton Malletier S.A. v. Haute Diggity Dog, LLC, 507 F.3d 252 (4th Cir. 2007), where "Chewy Vuiton" dog toys survived, is still good law and is more important than ever. The Fourth Circuit's insight was that a successful parody communicates two simultaneous messages, "this is the famous mark" and "this is emphatically not the famous mark," and that the second message reinforces rather than impairs the famous mark's distinctiveness. That is a blurring-factor argument, and it is exactly the argument a post-Jack Daniel's defendant must make.

The practical upshot: a parody defendant's brief should now be organized around similarity, exclusivity, and actual impairment, with the parodic message deployed as evidence on those factors, rather than around a categorical exclusion.

Part VI: Remedies

Injunctions are the default

Section 1125(c)(1) provides that the owner "shall be entitled to an injunction," subject to the principles of equity. After eBay Inc. v. MercExchange, L.L.C., 547 U.S. 388 (2006), courts apply the traditional four-factor test rather than presuming irreparable harm from a finding of liability. But note an important 2020 development: the Trademark Modernization Act amended 15 U.S.C. § 1116(a) to restore a rebuttable presumption of irreparable harm upon a finding of a violation (for permanent injunctions) or a showing of likelihood of success (for preliminary injunctions) in Lanham Act cases. That presumption applies to dilution claims as well as infringement claims, and it materially improved the position of brand owners seeking emergency relief. See Preliminary Injunctions and Temporary Restraining Orders.

Money requires willfulness

Under § 1125(c)(5), damages, profits, and destruction remedies under §§ 1117(a) and 1118 are available only where the defendant willfully intended to trade on the recognition of the famous mark (blurring) or willfully intended to harm the reputation of the famous mark (tarnishment). This is a high bar, and it is one reason dilution is usually a companion claim rather than the lead. Fee awards follow the "exceptional case" standard of § 1117(a), analyzed in Lanham Act Attorney's Fees Under 15 U.S.C. § 1117(a).

The registration defense

Section 1125(c)(6) provides that ownership of a valid federal registration on the Principal Register is a complete bar to any state-law dilution or similar claim. This is a genuinely powerful benefit of federal registration and one that is under-appreciated. It does not bar federal dilution claims, but it eliminates a whole category of state exposure. See Benefits of Federal Trademark Registration.

Part VII: Dilution at the TTAB

Dilution is an available ground for opposition under 15 U.S.C. § 1063 and for cancellation under § 1064, and unlike some grounds it is available against a registration of any age (dilution is not among the grounds limited to the first five years).

Three practice notes:

The fame standard is the same, and it is still the hard part. Coach Services arose from a TTAB proceeding, and its holding that fame for dilution requires a "more stringent showing" governs Board practice.

Fame must be proved as of the applicant's priority date, which is typically the filing date of the application. This can be earlier than the plaintiff expects.

The Board decides likelihood of dilution on the record before it, which means the evidentiary record built during the Board's discovery period does all the work. Surveys are admissible and are frequently outcome-determinative. See Discovery Practice in TTAB Trademark Proceedings and TTAB Practice Toolkit.

Part VIII: State antidilution law

Roughly half the states have antidilution statutes, and they matter for three reasons.

They may have a lower fame threshold. Many state statutes require only that the mark be "distinctive" or "famous in this state," which permits claims by regionally prominent brands that could never satisfy the TDRA. New York's General Business Law § 360-l is the most litigated example, requiring a showing of distinctiveness and a likelihood of dilution.

They may reach conduct the TDRA excludes. State courts are not bound by the federal exclusions, though First Amendment limits apply everywhere.

But § 1125(c)(6) is a complete defense if the defendant owns a federal registration on the Principal Register. That is often the decisive fact.

For plaintiffs, the strategic point is that a state claim can be worth pleading where fame is regional. For defendants, the strategic point is that federal registration is a shield, and obtaining one may be a defensive move worth making even in the middle of a dispute.

Part IX: Building and defending the case

Evidence a dilution plaintiff needs

  • Fame evidence, dated. Advertising expenditures by year and channel, unaided awareness studies if any exist, circulation and impression data, unsolicited media coverage, awards, and third-party references. Undated spending totals are the most common failure mode.
  • A fame survey. In serious cases, a properly designed survey measuring recognition among a general-population sample is the strongest available proof. It must sample the general consuming public, not category purchasers, which surprises marketing departments used to category-specific research. On methodology and admissibility see Consumer Survey Expert Methodology in Trademark Cases and Daubert Challenges to Consumer Survey Experts in Trademark Litigation.
  • Substantially exclusive use evidence. A clearance and watch file, records of enforcement letters sent and outcomes, coexistence agreements, and third-party registration analyses. This is factor (iii), and it is where a plaintiff's own sloppiness surfaces.
  • Timing evidence. Proof that fame preceded the defendant's first use.
  • Association evidence. A blurring survey (typically a modified Ever-Ready or association format) plus any anecdotal evidence of consumers linking the two.
  • Impairment evidence. The hardest piece, and the one Starbucks punished the plaintiff for omitting. Consider expert testimony on brand equity measurement, evidence of increased response latency in recognition tasks, or evidence of the plaintiff's own remedial spending.

Defenses that work

  • Attack fame first, and attack it as a binary. Cite Coach Services. Demand evidence of general-public recognition and point out that spending is an input, not an output.
  • Attack timing. Force the plaintiff to identify the date fame attached and test it.
  • Attack exclusivity. Run a third-party use search. Every coexisting user is evidence that the mark's distinctiveness was already dispersed.
  • Separate association from impairment. Starbucks is the template.
  • Deploy the exclusions carefully. Post-Jack Daniel's, ask first whether the client uses the matter as a source identifier for its own goods. If yes, the exclusions are largely unavailable and the fight moves to the factors.
  • Consider the registration defense to state claims under § 1125(c)(6).
  • Move early. Dilution counts are often dismissible on the pleadings for failure to plead fame plausibly, because conclusory fame allegations do not satisfy Ashcroft v. Iqbal, 556 U.S. 662 (2009). See Motions to Dismiss Under Rule 12.

A worked example

Meridian Financial Group (fictional) owns MERIDIAN for banking services. It has $9 billion in assets, operates in eleven states, spends $40 million a year on advertising, and is well known to anyone who follows regional banking. A software startup launches Meridian, a project management tool for construction firms.

Fame? Almost certainly not. Eleven states and industry prominence do not make a household name. Coach Services controls, and this claim should not be filed under the TDRA. A New York state claim might survive if the bank operates there and can show distinctiveness within the state.

Now change the facts. Meridian is instead one of the three largest consumer banks in the United States, with 60 million customers, national television advertising for thirty years, and unaided awareness of 71 percent in a general-population survey.

Fame? Now yes, and the survey is the reason.

Timing? The bank must show it was a household name before the startup's first use in 2019. Its 2016 tracking studies do that.

Blurring? The marks are identical, the bank's mark is arbitrary as applied to banking, the bank has enforced consistently and can prove substantially exclusive use, recognition is high, and the startup's founder wrote a Slack message saying "the name tests well because people already trust it." Factors (i) through (v) favor the bank. A properly designed association survey supplies factor (vi). The bank still must address impairment, and its expert should be prepared to explain, in terms a jury can follow, how a second commercial meaning degrades a singular one.

Exclusions? None apply. The startup uses MERIDIAN as a source identifier for its own product. This is Jack Daniel's, and there is no threshold escape.

Money? Only if the bank proves the startup willfully intended to trade on its recognition. That Slack message is now worth a great deal.

The startup's best moves. Attack exclusivity with a third-party use search (MERIDIAN is a common English word, and there are likely dozens of users across industries). Attack impairment under Starbucks. Emphasize the total absence of channel overlap and the sophistication of construction-industry buyers, which cuts against the confusion claim even if it does not formally bear on dilution. And, if the record is bad, rebrand early: dilution defendants who change names promptly usually settle for a fraction of what defendants who dig in end up paying.

Frequently asked questions

Do I need to prove confusion to win a dilution claim? No. The statute expressly says dilution is actionable "regardless of the presence or absence of actual or likely confusion, of competition, or of actual economic injury." That is the point of the claim.

Is my mark famous? Ask whether a random sample of American adults, not people in your industry, would recognize it as a brand. If you have to explain what your company does before the recognition kicks in, it is not famous under the TDRA. Fewer than a few hundred marks plausibly qualify.

Can a logo, a color, or product packaging be diluted? Yes. Trade dress and non-word marks can be famous and can be diluted, subject to the same standards. Functionality remains a separate and complete defense. See Design Patents vs. Trade Dress.

Does dilution apply to domain names? Yes, and it also underpins the cybersquatting cause of action in 15 U.S.C. § 1125(d), which has its own elements and its own remedies. For domain disputes, the UDRP is usually faster and cheaper. See How to File a UDRP Complaint for Domain Name Disputes.

We are making fun of a famous brand on a T-shirt. Are we safe? That depends on whether the joke functions as a brand for your shirt. After Jack Daniel's, using the parody as a source identifier removes the categorical exclusions and puts you into the ordinary factor analysis, where a successful parody can still win, as Haute Diggity Dog shows. Get advice before printing.

How does dilution interact with likelihood of confusion? They are independent claims with different elements and usually different evidence. Confusion protects consumers from deception; dilution protects the mark's distinctiveness. A plaintiff can win one and lose the other. For the confusion framework see Trademark Likelihood of Confusion Analysis and Navigating the Maze of Trademark Confusion.

Can I get damages? Only on proof of willful intent under § 1125(c)(5). Plan for an injunction and treat money as upside.

Should I plead dilution? Only if you can plead fame with specific factual allegations. A conclusory fame allegation invites a Rule 12(b)(6) motion, wastes credibility, and can color a judge's view of the whole complaint. If the mark is genuinely famous, plead it with the evidence.

Closing thought

Dilution is a narrow doctrine that gets pleaded broadly, and the mismatch does real damage to real cases. Courts have grown accustomed to seeing a dilution count attached to every trademark complaint, which means the count carries a presumption of overreach before anyone reads it.

The corrective is discipline. If your client's mark is a household word, dilution is a powerful claim, and the Jack Daniel's decision has made it more powerful by closing the parody escape hatch for source-identifying uses. If your client's mark is merely successful, dilution is a distraction that will be dismissed and will make the rest of your complaint look weaker.

For brand owners the long-run lesson is different and more useful: fame is built, documented, and defended. Keep dated evidence of recognition, run a real watch and enforcement program so you can prove substantially exclusive use, and register federally so that § 1125(c)(6) forecloses state claims against you. The evidentiary file you build in ordinary times is the case you get to put on when it matters.
