Common Law Trademark Rights

In the United States, while it is strongly advised that businesses and individuals register their trademarks with the U.S. Patent and Trademark Office (USPTO), it is not required in order to have trademark rights. Under Common Law, simply being the first to use a trademark automatically confers certain rights within the region that the trademark is being used. However, in many cases, it is not enough to rely on common law rights to protect your trademark.

Common Law vs. Federal Trademark Registration

One of the most important distinctions between common law trademark rights and federal registration of a trademark is that any common law protection is limited to the geographic area in which the trademark is continuously being used. For example, if a business markets and sells its products under an unregistered trademark in Los Angeles, that business may only have rights in Los Angeles. Thus, another business could potentially use the trademark in San Diego and even register the trademark with the USPTO to gain rights throughout the entire country.

One of the disadvantages of relying solely on common law trademark rights is that it is difficult to find the use when another party performs a trademark search. Therefore a subsequent user could perform a search and gain superior rights in most of the country without even knowing about the prior use.

On the other hand, having a federally registered trademark with the USPTO’s principal register gives a trademark owner considerably more protection. Registration creates a presumption of ownership and lets the public know that the registrant owns the trademark and has exclusive right to use the trademark throughout the U.S. and in connection with goods or services listed in the registration. Registrants may also take action against infringement, obtain foreign registration, and prevent importation of potentially infringing foreign goods.

What Factors Determine Common Law Trademark Rights?

Essentially, if a product or service is sold under a particular brand name that is not already in use or under trademark protection, the trademark owner may claim common law trademark rights. Additional requirements include:

  • Public association with the trademark
  • The trademark has acquired distinctiveness
  • The trademark owner exercises control over the quality of goods
  • The trademark owner has used the name as a trademark
