When the company behind the LEXIS legal-research service tried to stop Toyota from naming its new luxury cars LEXUS, the resulting opinion did two things at once: it refused the injunction, and it gave dilution law one of its most enduring analytical templates. In *Mead Data Central, Inc. v. Toyota Motor Sales, U.S.A., Inc.*, 875 F.2d 1026 (2d Cir. 1989), the Second Circuit held that the near-homonym posed no likelihood of dilution by blurring under New York's antidilution statute. The majority, in an opinion by Judge Ellsworth Van Graafeiland, reversed an injunction; Judge Robert W. Sweet, concurring, offered a six-factor framework for blurring that courts and commentators have cited ever since.

## At a glance

- **Case:** *Mead Data Central, Inc. v. Toyota Motor Sales, U.S.A., Inc.*, 875 F.2d 1026 (2d Cir. 1989).
- **Court:** U.S. Court of Appeals for the Second Circuit; majority opinion by Judge Ellsworth Van Graafeiland, concurrence by Judge Robert W. Sweet.
- **Posture:** Appeal from a Southern District of New York injunction barring Toyota's use of LEXUS; the Second Circuit reversed.
- **Holding:** No likelihood of dilution by blurring under N.Y. Gen. Bus. Law 368-d, because the marks were not substantially similar and LEXIS was strong only within the narrow market of legal professionals.
- **Significance:** Produced the widely cited "Sweet factors" for analyzing dilution by blurring and clarified the role of fame and similarity in dilution claims.

## Two marks, two very different audiences

Mead Data Central owned the trademark LEXIS for its pioneering computerized legal-research service, a tool nearly ubiquitous among lawyers but largely unknown to the general public. Toyota planned to introduce a new line of luxury automobiles under the name LEXUS. Mead sued under New York's antidilution statute, then codified at N.Y. Gen. Bus. Law Section 368-d, seeking to enjoin Toyota's use of the name on the theory that LEXUS would dilute the distinctiveness of LEXIS.

The district court agreed and issued an injunction. The Second Circuit reversed. Dilution, the court explained, can occur through blurring—the whittling away of a mark's selling power as a unique identifier—or through tarnishment, the linking of a mark to inferior or unsavory associations. Mead did not claim tarnishment; its luxury-car opponent threatened nothing unsavory. The sole question was whether LEXUS was likely to blur LEXIS.

## Why there was no likelihood of blurring

The majority concluded that blurring was unlikely for two connected reasons. First, the marks were not substantially similar in the relevant sense. Although LEXIS and LEXUS are spelled almost identically and overlap in sound, the court emphasized differences in appearance and in how the general public would encounter and pronounce them, and stressed that dilution analysis must consider how ordinary consumers, not just specialists, perceive the marks.

Second, and decisively, the court examined the strength and renown of the senior mark. LEXIS was a powerful mark, but only within a narrow professional community: attorneys and accountants who used the research service. To the general public—the audience that would buy or notice a luxury car—LEXIS meant essentially nothing. The very sophistication of LEXIS's actual users made it unlikely that they would confuse or blur the legal-research mark with an automobile. Dilution doctrine protects famous marks against the erosion of their distinctiveness in the public mind, and a mark known only to a specialized group has little of that broad distinctiveness to lose. The injunction was reversed.

## Judge Sweet's six factors

The lasting doctrinal contribution came from Judge Sweet's concurrence. While he agreed with the result, he set out a structured, six-factor test for assessing dilution by blurring. The factors are: (1) the similarity of the marks; (2) the similarity of the products covered by the marks; (3) the sophistication of consumers; (4) predatory intent on the part of the junior user; (5) the renown of the senior mark; and (6) the renown of the junior mark.

These "Sweet factors" gave courts a checklist where the statute had offered only the general concept of dilution. They were widely embraced in the Second Circuit and cited well beyond it, becoming the standard analytical vocabulary for blurring claims under state law. Judge Sweet did differ with the majority on some points—he viewed LEXIS as a stronger mark and the marks as more similar in pronunciation than the majority allowed—but applying his own factors, he too concluded there was no actionable dilution. The factors, not the disagreement, are what endured.

## From state law to the federal statutes

*Mead Data* arose under New York law because, in 1989, there was no general federal dilution cause of action; protection depended on a patchwork of state antidilution statutes. That changed with the Federal Trademark Dilution Act of 1995 and, more significantly, the Trademark Dilution Revision Act of 2006, which rewrote the federal standard at 15 U.S.C. Section 1125(c). The federal statute requires that the senior mark be famous to the general consuming public—precisely the kind of broad renown LEXIS lacked—and supplies its own non-exclusive list of factors for blurring, several of which echo Judge Sweet's.

The result is that *Mead Data* is partly absorbed and partly superseded. Its insistence that dilution protects broadly famous marks anticipated the federal fame requirement, and the Sweet factors prefigured the statutory list. But practitioners bringing dilution claims today generally proceed under the federal statute's framework, citing *Mead Data* for its analysis rather than as the governing rule.

## Open questions

- **How famous is famous enough?** *Mead Data* held niche renown insufficient, but the line between specialized strength and the general fame dilution requires remains contested under the federal statute.
- **How much similarity does blurring need?** The case treated appearance and pronunciation as central, yet courts still divide over how close two marks must be before blurring is plausible.
- **What weight does predatory intent carry?** Judge Sweet listed intent as a factor, but its proper role—aggravating, threshold, or merely probative—was never fully settled.

## Implications

- **Dilution rewards true fame.** A mark powerful only within a profession or niche may lack the broad renown dilution law protects, as LEXIS learned.
- **Similarity is judged through the public's eyes.** Near-identical spelling does not guarantee a blurring claim if ordinary consumers perceive the marks differently.
- **The Sweet factors remain a useful map.** Even under the federal statute, counsel and courts still reach for the six-factor framework to organize a blurring analysis.
- **Plead the right theory.** Mead pursued blurring, not tarnishment; choosing the correct dilution theory shapes the entire case.
- **Know which statute governs.** Modern dilution claims usually run through 15 U.S.C. 1125(c); *Mead Data* is persuasive analysis, not the controlling federal test.

## Frequently asked questions

**Who won Mead Data Central v. Toyota?**
Toyota won. The Second Circuit reversed the district court's injunction and allowed Toyota to use the LEXUS name, finding no likelihood of dilution by blurring under New York's antidilution statute because the marks were not substantially similar and LEXIS was strong only among sophisticated legal professionals.

**What are Judge Sweet's six factors for dilution by blurring?**
In his concurrence, Judge Sweet proposed weighing: similarity of the marks; similarity of the products covered; sophistication of consumers; predatory intent; the renown of the senior mark; and the renown of the junior mark. These became widely cited as the Sweet factors.

**Is Mead Data still good law after the federal dilution statutes?**
It remains an influential blurring analysis, but federal law has since evolved. The Federal Trademark Dilution Act of 1995 and the Trademark Dilution Revision Act of 2006 created a federal cause of action with their own statutory blurring factors and a fame requirement, partly absorbing and partly superseding the state-law framework.
