A suggestive mark is a mark that evokes or suggests a characteristic of the underlying good. For example, the word “Coppertone” is suggestive of sun-tan lotion, but does not specifically describe the underlying product.
Some exercise of imagination is needed to associate the word with the underlying product. At the same time, however, the word is not totally unrelated to the underlying product. Like arbitrary or fanciful marks, suggestive marks are inherently distinctive and are given a high degree of protection.
A descriptive mark is a mark that directly describes, rather than suggests, a characteristic or quality of the underlying product (e.g. its color, odor, function, dimensions, or ingredients).
For example, “Holiday Inn,” “All Bran,” and “Vision Center” all describe some aspect of the underlying product or service (respectively, hotel rooms, breakfast cereal, and optical services).
They tell us something about the product. Unlike arbitrary or suggestive marks, descriptive marks are not inherently distinctive and are protected only if they have acquired “secondary meaning.”
Descriptive marks must clear this additional hurdle because they are terms that are useful for describing the underlying product, and giving a particular manufacturer the exclusive right to use the term could confer an unfair advantage.
A descriptive mark acquires secondary meaning when the consuming public primarily associates that mark with a particular producer, rather than the underlying product.
Thus, for example, the term “Holiday Inn” has acquired secondary meaning because the consuming public associates that term with a particular provider of hotel services and not with hotel services in general.
The public need not be able to identify the specific producer; only that the product or service comes from a single producer.
When trying to determine whether a given term has acquired secondary meaning, courts will often look to the following factors: (1) the amount and manner of advertising; (2) the volume of sales; (3) the length and manner of the term’s use; (4) results of consumer surveys.
Finally, a generic mark is a mark that describes the general category to which the underlying product belongs. For example, the term “Computer” is a generic term for computer equipment.
Generic marks are entitled to no protection under trademark law. Thus, a manufacturer selling “Computer” brand computers (or “Apple” brand apples, etc.) would have no exclusive right to use that term with respect to that product.
Generic terms are not protected by trademark law because they are simply too useful for identifying a particular product. Giving a single manufacturer control over use of the term would give that manufacturer too great a competitive advantage.
Under some circumstances, terms that are not originally generic can become generic overtime (a process called “generosity”), and thus become unprotected.
