A failure to function as a trademark refusal is issued when the USPTO determines the proposed mark does not serve the fundamental trademark purpose of identifying and distinguishing the source of goods or services. The mark may be a word, phrase, or design, but it is not perceived by consumers as a brand identifier.

Common reasons include: the term is a widely used slogan or commonplace expression that consumers would not associate with any single source ("Think Different" was initially challenged on this basis), the design is purely ornamental, the mark is used in a purely informational way rather than as a brand, or the term is so commonly used in the industry that it cannot function as a source identifier for any one company.

Overcoming this refusal requires demonstrating that the mark is used in a way that consumers do associate with a single commercial source; through evidence of long and exclusive use, consumer recognition, and consistent brand-building use of the mark.
