Why Some Trademarks Are Stronger Than Others

By Hank FasthoffJune 9, 2026

Every trademark falls somewhere on a spectrum of distinctiveness that runs from fanciful (the strongest) to generic (the weakest, and unprotectable). A mark's place on that spectrum determines whether it qualifies for federal registration, how broad its protection will be, and how much effort enforcement will require. A business that picks a strong mark from the start may spend less on lawyers and more on growth, but a business that picks a weak one may later discover the problem only when someone else starts using a similar name and the trademark office or a court says the mark was never protectable to begin with.

The trademark strength spectrum has five levels. Understanding them is the single most important step a business owner can take before choosing a brand name.

Fanciful Marks

A fanciful mark is an invented word with no meaning outside of its use as a trademark. XEROX, KODAK, EXXON, and PEPSI are all fanciful marks. These words didn't exist in any language before their owners created them to identify products.

Fanciful marks receive the broadest protection available under trademark law. Because the word has no meaning apart from the brand, any use of the same or a similar word in connection with related products or services is likely to create consumer confusion. Courts don't need to analyze whether the word describes some quality of the goods or has an independent meaning that limits the scope of protection. The word means one thing, and one thing only.

The tradeoff is that a fanciful mark requires more upfront investment in advertising and marketing, because consumers have no preexisting association with the word. XEROX spent years building the association between its invented name and copying machines. But that investment paid off in the form of a trademark that is effectively impossible for competitors to challenge or design around.

Arbitrary Marks

An arbitrary mark is a real word used in a context unrelated to its ordinary meaning. APPLE for computers, AMAZON for an online retailer, and SHELL for gasoline are arbitrary marks. The words themselves are common English, but they have no connection to the products they identify.

Arbitrary marks receive protection nearly as broad as fanciful marks because the ordinary meaning of the word doesn't describe anything about the product. No computer company needs the word "apple" to describe its goods. No gas station needs the word "shell" to communicate what it sells. The disconnect between the word and the product is what makes arbitrary marks strong.

The advantage over fanciful marks is that consumers already know the word, which can make marketing somewhat easier. The limitation is that the mark is strong only in the context where it's being used. Apple's trademark rights in APPLE for use with computers (and various other related services) wouldn't prevent another company from using APPLE in connection with entirely unrelated goods or services.

Suggestive Marks

A suggestive mark hints at a quality or characteristic of the product without directly describing it. The consumer has to use some imagination to connect the mark to the product. COPPERTONE for sunscreen (suggests a copper tan), IGLOO for use with ice chests (suggests cold temperatures), and GREYHOUND for bus service (suggests moving with speed) are suggestive marks.

Suggestive marks are registrable on the principal register without proof of secondary meaning, and they receive solid protection in enforcement actions. The line between suggestive and descriptive is one of the most frequently litigated issues in trademark law, and reasonable people (and judges) often disagree about which side of that line a particular mark falls on.

Suggestive marks appeal to businesses because they communicate something about the product while still maintaining enough distinctiveness to function as trademarks. They're a compromise between the branding power of a descriptive name and the legal strength of an arbitrary one.

Descriptive Marks

A descriptive mark directly tells the consumer something about the product, or describes its purpose, its quality, its ingredients, or some other characteristic. SHARP for televisions, BEST BUY for a discount electronics retailer, and INTERNATIONAL BUSINESS MACHINES (IBM) for computers are descriptive marks.

Descriptive marks cannot be registered on the principal register unless the owner proves that the mark has acquired secondary meaning. Secondary meaning (also called acquired distinctiveness) exists when consumers have come to associate the descriptive term with a particular source rather than its dictionary definition. Proving secondary meaning typically requires evidence of extensive advertising expenditures, long and exclusive use, consumer surveys, or media coverage. A descriptive mark without secondary meaning can still register on the supplemental register, which provides some benefits while the owner builds the evidence needed for the principal register.

Even after acquiring secondary meaning, descriptive marks receive narrower protection than suggestive, arbitrary, or fanciful marks. The owner of a descriptive mark can't prevent competitors from using the same word in its descriptive sense. SHARP can't stop a competitor from advertising that its televisions have "sharp" picture quality. BEST BUY can't stop a competitor from claiming it offers the "best buy" in electronics.

Descriptive marks appeal to businesses because they tell consumers exactly what the product or service is, reducing the need for expensive marketing. The cost of adopting a descriptive mark is weaker legal protection and a harder registration process. Many businesses choose descriptive names because they seem like good marketing, only to discover later that they've built their brand on a foundation that's difficult to defend.

Generic Terms

A generic term is the common name for a product or service. "Computer" for computers, "email" for electronic mail services, and "restaurant" for a restaurant are all generic terms. No one can acquire trademark rights in a generic term.

Generic terms can never be registered as trademarks, and any trademark that becomes generic loses its protection. This process, called genericide, has claimed marks that were once among the most valuable in the world. ASPIRIN, THERMOS, ESCALATOR, and TRAMPOLINE were all once enforceable trademarks that became generic through widespread use of the brand name as the common term for the product.

Genericide is an ongoing threat to successful brands. When consumers and the media start using a trademark as a noun or verb rather than an adjective (saying "google it" instead of "search using the Google search engine"), the owner has a warning sign worth acting on, though verb use alone doesn't make a mark generic. Trademark owners combat genericide through advertising campaigns that emphasize proper trademark use, cease and desist letters, and consistent use of the mark as an adjective followed by the generic term.

Choosing the Right Mark

The spectrum of distinctiveness dictates a direct tradeoff between marketing convenience and legal strength. Descriptive and generic names are easiest for consumers to understand but hardest (or impossible) to protect. Fanciful and arbitrary names require more investment to build consumer recognition but offer the strongest legal protection.

The strongest approach is to choose a fanciful or arbitrary mark and invest in building the association between the mark and the product through marketing. The second best approach is a suggestive mark that hints at what the product does without directly describing it. Descriptive marks should be a last resort, chosen only with full awareness that registration will require proof of secondary meaning and enforcement will always be more difficult.

The worst approach, and the most common one, is choosing a name without consulting a trademark attorney and discovering years later that the name falls too low on the spectrum to protect. By that point, the business has invested in signage, packaging, marketing, and customer recognition that are all tied to a name the law won't let it own.
