What is an example of a service mark?

A service mark is a specific type of trademark that identifies and distinguishes the source of a service rather than a product. While logos generally serve as trademarks for products, a service mark is associated with services that a company provides.

In this context, Facebook provides various online services including social networking, advertising, and more. The Facebook logo acts as a service mark because it represents the company's services and helps consumers identify and associate these services with the Facebook brand.

In contrast, the Twitter logo, the McDonald's arch, and the Coca Cola bottle shape all relate to products or product offerings of their respective brands and are more representative of trademarks than service marks. The distinct roles of identifying a service versus a product are key to understanding the nature of a service mark.
