Trademark law encompasses the protection and enforcement of words, symbols, or phrases used to identify the source of a particular product or service. Some of the most famous trademarks in the world include APPLE®, GOOGLE®, MCDONALD’S®, and MICROSOFT®. Trademarks are governed by state law and the federal Lanham Act, which allow trademark owners to claim exclusive rights to use and register all protectable marks.

A mark is deemed protectable if it is distinctive, meaning that it is capable of identifying the source of a particular good. In determining whether a mark is distinctive, trademark law uses four separate classifications based on the relationship between the mark and the associated product: (1) arbitrary or fanciful (marks such as KODAK® and APPLE® that bear no inherent relationship to their associated products); (2) suggestive (marks such as COPPERTONE® that evoke a characteristic of the associated products); (3) descriptive (marks such as HOLIDAY INN® that directly describe a characteristic or feature of the associated products); or (4) generic (terms that describe the general category of the associated products, e.g., “phone,” “keyboard,” etc.). The first two categories of marks are protectable without proof that they have acquired distinctiveness in the minds of consumers, while descriptive marks require evidence that the consuming public has come to associate the term with its specific source. Generic terms are never protectable as trademarks, as they are necessary for general identification of a particular product category.

Once a trademark owner has acquired protectable rights in a mark, it may enforce its rights by preventing the use and/or registration of all subsequent infringing marks. The standard for infringement in the United States is “likelihood of confusion,” which means that consumers viewing the respective marks on their associated products are likely to be confused as to the source of those products or as to the sponsorship or approval of such products. In other words, determining infringement is not as simple as merely comparing the marks to see if they are identical; rather, courts will employ a multifactor test. While the precise factors vary slightly by jurisdiction, courts generally consider the following elements: (1) the strength of the plaintiff’s mark; (2) the relatedness of the goods; (3) the similarity of the marks; (4) evidence of actual confusion; (5) the similarity of marketing channels used; (6) the degree of care exercised by the typical purchaser; (7) the defendant’s intent; and (8) the likelihood of expansion of the product lines.

Protecting and enforcing trademarks is critical to the success of any company. Trademarks allow consumers to distinguish a company’s products and services from those of its competitors, and also serve as indicators of the quality of such products and services. Indeed, many companies’ trademark portfolios constitute the majority of the value of their businesses.
