Trademark

A trademark is a recognizable sign, design, or expression that identifies products or services of a particular source from those of others. It can be a word, phrase, symbol, or a combination of these elements. The ultimate purpose of a trademark is to prevent confusion among consumers about the origins of goods or services. Examples include the Nike swoosh and the McDonald’s golden arches. Notable cases include the *Qualitex Co. v. Jacobson Products Co.* decision, which upheld the validity of color trademarks, and *Matal v. Tam*, which addressed free speech in trademark registration.
