A Service Mark identifies one specific service provider, for example, one specific plumber or one specific plumbing company. A Service Mark is used by a person or company for the purposes of distinguishing their services from the services of others.

A Service Mark is any word, symbol, logo, slogan, design or any combination of these used to specifically identify services rendered. A Service Mark is a type of Trademark. The main difference between a Trademark and a Service Mark is that a Trademark identifies the supplier of goods and a Service Mark identifies a specific provider of services.

In some cases the words Trademark or simply Mark can refer to a Service Mark.

Once a Service Mark is registered, the SM symbol may be used on brochures and advertisements for services.
