Definition[]
U.S. trademark law[]
Under the Lanham Act, a service mark is
| “ | any word, symbol, name or device or any combination thereof used to identify the source of commercial services and to distinguish the services from those of another provider.[1] | ” |
A service mark is the same as a trademark except that it identifies and distinguishes the source of a service rather than goods. The terms "trademark" and "mark" are often used to refer to both trademarks and service marks.
