Catchphrases can be eligible for trademark protection in certain circumstances. In order to be eligible for trademark protection, a catchphrase must be used in connection with goods or services, and it must be distinctive and capable of identifying the source of those goods or services.

Catchphrases that are merely descriptive or that are commonly used in the industry may not be eligible for trademark protection. In order to be distinctive and capable of identifying the source of goods or services, a catchphrase must be unique or unusual enough that it is not likely to be confused with the catchphrases of other businesses.

In order to obtain trademark protection for a catchphrase, it is generally necessary to apply for a trademark registration with the United States Patent and Trademark Office (USPTO) or a similar national or international trademark office. The catchphrase must be properly used in connection with the goods or services it is intended to identify, and it must be properly promoted and maintained in order to retain trademark protection.

It is a good idea to consult with a trademark attorney or other professional to determine whether a catchphrase is eligible for trademark protection and to assist with the trademark registration process.
