The Spectrum of Distinctiveness: How Strong Is Your Mark?

trademark law categorizes marks along a spectrum from strongest to weakest. fanciful marks are invented words with no meaning outside their use as a brand, such as KODAK or EXXON[26]. They are inherently distinctive and the easiest to register. arbitrary marks are real words used in unrelated contexts, like AMAZON for an online retailer or CAMEL for cigarettes[27]. These marks have inherent distinctiveness because they bear no direct relation to the goods or services. suggestive marks hint at a product’s qualities without describing it. COPPERTONE implies a suntan but does not explicitly state what the product is[28]. Suggestive marks are protectable because consumers must use imagination to connect the mark to the goods. descriptive marks directly describe an ingredient, quality or characteristic of the goods—examples include BRITISH AIRWAYS and SPORTS ILLUSTRATED[29]. Descriptive marks are not registerable without proof of “secondary meaning,” meaning consumers associate the term with a single source[30]. Generic terms are the common names of products and cannot be registered at all[9].

The Abercrombie Spectrum

The Abercrombie spectrum (named after a landmark case, Abercrombie & Fitch Co. v. Hunting World Inc.) provides a framework for evaluating the strength of a trademark. At one end are fanciful marks, invented words with no prior meaning, like XEROX or KODAK[26]. Because they are inherently distinctive, fanciful marks enjoy immediate protection and are relatively easy to enforce. Next are arbitrary marks—real words used in an unrelated context, such as APPLE for computers or CAMEL for cigarettes[27]. These marks are also strong because they do not describe or suggest the goods. Suggestive marks hint at the nature or quality of the goods without directly describing them. Marks like COPPERTONE and NETFLIX require consumers to exercise imagination to connect the mark with the product[28]. Suggestive marks are protectable without proof of acquired distinctiveness, but they occupy a middle ground on the spectrum. Descriptive marks describe an ingredient, quality, characteristic, function or feature of the goods, such as SHADE TREE MECHANIC for auto repair services. These marks are only registrable if they have gained secondary meaning, demonstrating that consumers associate the term with a single source[31]. At the weakest end are generic terms. These are common names for products or services—like “car” for automobiles or “aspirin” for acetylsalicylic acid—and cannot function as trademarks[9]. When a mark becomes generic through widespread use of the brand name as the name of the product, it loses protection. Preventing genericide requires careful branding and policing.

Evaluating Your Proposed Mark

To evaluate a proposed mark, locate it on the spectrum. Ask yourself: Does the mark immediately convey the nature of the goods or services? If so, it is likely descriptive and may face registration obstacles. Does it require imagination to connect the mark with the goods? Then it may be suggestive and potentially strong. Does the mark have no relation to the goods? It is arbitrary and inherently distinctive. For new brands, selecting fanciful or arbitrary marks generally provides the greatest protection, albeit at the cost of requiring more marketing to educate consumers.

Secondary Meaning and Acquired Distinctiveness

Descriptive marks can still be registered if they acquire secondary meaning. This occurs when consumers come to recognize the mark as identifying a single source. Evidence of secondary meaning may include long‑term exclusive use, substantial advertising expenditures, sales success, consumer surveys and unsolicited media coverage[30]. Examples of descriptive marks that have acquired distinctiveness include AMERICAN AIRLINES and SHARP for televisions. Proving secondary meaning can be expensive and time consuming, so choose suggestive, arbitrary or fanciful marks when possible.

Practical Guidance

When choosing a brand name, aim for fanciful, arbitrary or suggestive marks. These inherently distinctive marks provide broader protection and require less effort to register. Avoid descriptive or generic terms; they are more likely to be refused and, even if registered, are harder to enforce. Use the spectrum of distinctiveness as a strategic tool to evaluate potential marks and make informed branding decisions. Incorporate it into your brainstorming process, and consult legal counsel if you are uncertain about where a mark falls on the spectrum. Investing in a strong mark at the outset will save time and resources later.
