Service mark

A service mark or servicemark is a trademark used in the United States and several other countries to identify a service rather than a product. When a service mark is federally registered, the standard registration symbol ® or "Reg U.S. Pat & TM Off" may be used (the same symbol is used to mark registered trademarks). Before it is registered, it is common practice (with some legal standing) to use the service mark symbol ℠ (a superscript SM).

Usage

A service mark differs from a trademark in that the mark is used on the advertising of the service rather than on the packaging or delivery of the service, since there is generally no "package" to place the mark on, which is the practice for trademarks. For example, a private carrier can paint its service mark on its vehicles, such as on planes or buses. Personal service providers can place their service marks on their delivery vehicles, such as on the trucks of plumbers or on moving vans. However, if the service deals with communications, it is possible to use a service mark consisting of a sound (a sound trademark) in the process of delivering the service. This has been done in the case of AT&T, which uses a tone sound followed by a woman speaking the company's name to identify its long distance service; MGM, which uses the sound of a lion's roar; and RKO, which uses a Morse code signal for their motion pictures.
