U+00AE "®" Registered Sign Unicode Character
Unicode Version 17.0
®
U+00AE "®" Registered Sign is a typographic symbol used to indicate that a specific trademark has been officially registered with a national or regional trademark office, such as the United States Patent and Trademark Office. It typically appears as a small capital letter R enclosed within a circle and is placed in superscript after a brand name, logo, or slogan to notify the public of legal protection and to deter unauthorized use. Unlike the similar but distinct "™" (Trademark) symbol for unregistered marks, the Registered Sign carries specific legal implications regarding ownership and enforcement rights.
