Patent & Trademark Resource Center: Trademarks


What is a trademark?

A trademark is generally a word, phrase, symbol, or design, or a combination thereof, that identifies and distinguishes the source of the goods of one party from those of others.

What is a service mark?

A service mark is the same as a trademark, except that it identifies and distinguishes the source of a service rather than goods.
