Why Some Trademarks Are Stronger Than Others

By Hank FasthoffJune 9, 2026

Trademark strength affects registration, enforcement, and the range of similar uses an owner may challenge. Lawyers evaluate strength in two ways. Conceptual strength concerns how distinctive a mark is in relation to its goods or services, while commercial strength concerns the degree to which consumers recognize the mark as identifying one source.

The familiar spectrum addresses conceptual strength. USPTO examination guidance classifies terms as fanciful, arbitrary, suggestive, descriptive, or generic, though courts and the USPTO sometimes group fanciful and arbitrary marks together. A mark's category always depends on the goods or services it identifies.

Fanciful Marks

A fanciful mark is a coined term used to identify a source. The USPTO lists EXXON for petroleum and PEPSI for soft drinks as examples. Because these terms have no ordinary meaning in relation to the identified products, they are inherently distinctive and eligible for the Principal Register without evidence of acquired distinctiveness.

Fanciful marks begin with substantial conceptual strength, but their protection isn't unlimited. Priority, abandonment, the similarity of the marks, the relationship between the goods or services, and the remaining likelihood of confusion factors may affect an infringement claim. A new fanciful mark may also have little commercial strength until consumers encounter it in the marketplace.

Arbitrary Marks

An arbitrary mark uses a familiar word for goods or services unrelated to its ordinary meaning. APPLE for computers is the standard example. The word identifies a type of fruit in one context and functions as an inherently distinctive mark in another.

Arbitrary marks also begin with substantial conceptual strength. In an ordinary infringement claim, however, the owner must establish likely consumer confusion based on the full record. The relationship between the parties' goods or services is part of that analysis.

Famous marks may receive separate protection against dilution. Section 43(c) of the Lanham Act permits claims for likely dilution by blurring or tarnishment without requiring likely confusion or competition, but only a mark widely recognized by the general consuming public satisfies the federal fame standard.

Suggestive Marks

A suggestive mark requires imagination or thought to connect the term with a quality of the goods or services. COPPERTONE for suntanning products suggests the appearance of copper toned skin without directly naming a product feature. Suggestive marks are inherently distinctive and may register on the Principal Register without acquired distinctiveness.

Suggestive marks often combine marketing appeal with legal protection, but category alone doesn't set the scope of enforcement. Commercial recognition and third party use of similar marks may strengthen or weaken the owner's position. The boundary between suggestive and descriptive terms also depends on the specific mark and goods or services.

Descriptive Terms

A descriptive term immediately conveys an ingredient, quality, characteristic, function, feature, purpose, or use of the goods or services. The USPTO uses CREAMY for yogurt, APPLE PIE for potpourri, and BED & BREAKFAST REGISTRY for lodging reservation services as examples. Under Section 2(e)(1) of the Lanham Act, a term that is merely descriptive of the identified goods or services can't register on the Principal Register without acquired distinctiveness.

Acquired distinctiveness, also called secondary meaning, exists when consumers understand the descriptive term as identifying a particular source. Evidence may include the duration and exclusivity of use, sales, advertising, unsolicited media coverage, copying, and consumer surveys. Advertising expenditures support the inquiry only to the extent they help show consumer source recognition.

Section 2(f) permits the USPTO to accept substantially exclusive and continuous use for the preceding five years as prima facie evidence in appropriate cases. Under Section 23, a descriptive term in lawful use may also qualify for the Supplemental Register if it is capable of distinguishing the applicant's goods or services, although that registration doesn't establish acquired distinctiveness.

Descriptive marks often receive a narrower scope of protection because competitors may need the same wording to describe their goods or services. Even after a descriptive term acquires trademark significance, Section 33(b)(4) preserves good faith descriptive use by another business when the term is used other than as a mark.

Generic Terms

A generic term names a class of goods or services and can't function as a trademark for that class. COMPUTER for computers and RESTAURANT for restaurant services are generic. The same word may belong to a different category when used for other goods or services, as APPLE does for computers.

A distinctive mark may lose protection if the relevant public comes to understand it primarily as the common name for the goods or services. ASPIRIN and ESCALATOR are familiar United States examples. Owners often respond by using the mark with the product's generic name, educating licensees and the public, and correcting uses that treat the mark as the product category.

Grammar alone doesn't determine whether a mark has become generic. In Elliott v. Google, Inc., 860 F.3d 1151, 1162-63 (9th Cir. 2017), the Ninth Circuit rejected the argument that using GOOGLE as a verb necessarily made the mark generic. The governing question was whether the relevant public primarily understood the term as the name of a product category or as an indicator of source.

Commercial Strength Changes Over Time

Conceptual strength concerns a mark's inherent characteristics, while commercial strength concerns marketplace recognition. Courts and the Trademark Trial and Appeal Board may consider sales, advertising, duration of use, media attention, consumer surveys, and the extent of third party use. Widespread use of similar marks for related goods or services may narrow the protection afforded a mark because consumers learn to distinguish among similar terms.

These two dimensions don't always point in the same direction. A newly adopted fanciful mark may have substantial conceptual strength and little commercial recognition. A descriptive mark that has acquired distinctiveness may become commercially strong through extensive use and consumer recognition.

Distinctiveness and Clearance Answer Different Questions

Selecting a fanciful, arbitrary, or suggestive term improves the candidate's inherent distinctiveness. A business should conduct a separate clearance search to assess whether another party has earlier rights in the same or a confusingly similar mark. Conceptual strength doesn't cure a conflict with a prior user.

Trademark selection should therefore evaluate the proposed mark in relation to the identified goods or services, comparable marks already in use, and federal and state records. That review allows a business to choose a mark that can identify its source without inheriting a registration obstacle or infringement dispute.
