Nominative use
Nominative use, also "nominative fair use", is a legal doctrine that provides an affirmative defense to trademark infringement as enunciated by the United States Ninth Circuit, by which a person may use the trademark of another as a reference to describe the other product, or to compare it to their own. Nominative use may be considered to be either related to, or a type of "trademark fair use" (sometimes called "classic fair use" or "statutory fair use").
