A trademark is a brand name. A trademark or service mark includes any word, name, symbol, device, or any combination, used or intended to be used to identify and distinguish the goods/services of one seller or provider from those of others, and to indicate the source of the goods/services.
A service mark is a word, phrase, symbol or design, or a combination thereof, that identifies and distinguishes the source of a service, rather than goods. The term “trademark” is often used to refer to both trademarks and service marks.
