When and How Should a Trademark Owner Use the ® Symbol?

The ® symbol may only be used in connection with marks that are registered with the PTO and only when used in connection with the goods or services covered by the registration. The symbol should be displayed next to the word, logo, or drawing which is registered at least once in all advertising and promotional materials. In addition or as an alternative, the notation “Marca Registrada” or “Registered in the United States Patent Office” may also be used. Similarly, a legend may be used stating that the words or logo are “a registered trademark of…” or simply “®” followed by the name of the corporate owner. Failure to include some indication that the mark is registered may result in a denial of certain damage awards in an infringement action.
