In trademark litigation, courts are most frequently asked to distinguish between
suggestive and
descriptive marks on the one hand, and between
descriptive and
generic marks on the other. This is because suggestive marks, like fanciful and arbitrary marks, are presumed to be entitled to trademark protection, while descriptive marks are entitled to protection if they have become known as representing the producer of the goods, and generic marks can never receive protection. It can be seen from the examples above that the distinctive character of a term is closely related to the products or services in relation to which the term is used. A general method for assessing the distinctive character of a mark is to consider a consumer's reaction to a mark. Therefore marks that identify or describe a product or service, or that are in common use, or that are used as
geographical indications, generally cannot be registered as trademarks, and remain in the
public domain for use by anyone. However, most jurisdictions may still allow such marks to be registered if the trademark owner can demonstrate, typically by reference to
evidence of use, that consumers in the marketplace exclusively associate the mark, as used on the identified goods or in connection with the identified services, with a particular commercial origin or source (i.e. the trademark owner). "Use" may include authorized use by a licensee or other party. If the trade mark office is satisfied that the evidence demonstrates that a mark has "acquired" distinctive character
as a matter of fact, then the mark may be accepted for registration on the basis of
acquired distinctiveness. The nature and extent of acceptable evidence of use varies between jurisdictions, although the most useful evidence usually includes sales figures, details of advertising and promotional expenditure, and examples of promotional material. Consumer surveys may also help establish that consumers chiefly associate an otherwise non-distinctive mark with the trademark owner and its products or services. Generally, evidence of use may only be acceptable or relevant if it covers a certain period of time (e.g. three years prior to the filing date of the trademark application) and originates from within the jurisdiction where registration is sought. The terminology of acquired distinctiveness is accepted in the
European Union and
Commonwealth jurisdictions such as
Australia,
Hong Kong and the
United Kingdom, and the common law jurisdiction of the
United States (which also uses the term
secondary meaning). In the U.S., if a trademark has been used for a continuous period of at least five years after the date of registration, the right to use the mark and the registration may become "incontestable" (e.g. invulnerable to cancellation for non-use, but not for becoming
generic). In such cases the
USPTO checks and confirms whether the request for incontestability meets formality requirements, but whether a registration is incontestable at law can only be determined during legal proceedings involving the registration. The essential function of a trademark is to exclusively identify the commercial source or origin of products or services, such that a trademark, properly called, indicates source or serves as a badge of origin. The use of a trademark in this way is known as trademark use. Certain exclusive rights attach to a registered mark, which can be enforced by way of an action for trademark infringement, while unregistered trademark rights may be enforced pursuant to the common law tort of
passing off. Trademark rights generally arise out of the use and/or registration (see below) of a mark in connection only with a specific type or range of products or services. Although it may sometimes be possible to take legal action to prevent the use of a mark in relation to products or services outside this range (e.g. for passing off), this does not mean that trademark law prevents the use of that mark by the general public. A common word, phrase, or other sign can only be removed from the public domain to the extent that a trademark owner is able to maintain exclusive rights over that sign in relation to certain products or services, assuming there are no other trademark objections. For a case study in both concepts, see
Apple Corps v Apple Computer. Maintaining distinctiveness If a court rules that a trademark has become "
generic" through common use (such that the mark no longer performs the essential trademark function and the average consumer no longer considers that exclusive rights attach to it), the corresponding registration may also be ruled invalid. though for certain trademarks, use as nouns and, less commonly, verbs is common. For example,
Adobe sent e-mails to many web authors using the term "
photoshopped" telling them that they should only use the term "modified by Adobe® Photoshop® software." Xerox has also purchased print advertisements declaring that "you cannot 'xerox' a document, but you can copy it on a Xerox Brand copying on machine." Another popular example is the use of the word "
frappuccino" by
Starbucks customers to mean any blended coffee beverage, though employees are instructed to only say "frappuccino blended coffee" or "frappuccino blended cream" when referring to such drinks. This rule is not hard-and-fast, however; for example, Lexis-Nexis has a U.S. trademark registration for "Shepardize," Reg. No. 1743711, and defines "Shepardizing on a web page as "the process of looking up citations" in "a series of books called Shepard's Citations." Such efforts may or may not be successful in preventing genericism in the long run, which depends less on the mark owner's efforts and more on how the public actually perceives and uses the mark. In fact, legally it is more important that the trademark holder visibly and actively seems to attempt to prevent its trademark from becoming generic, regardless of real success. ==See also==
