Adding R below a foreign trademark means "registered trademark", which means that the trademark has applied for registration in the State Trademark Office and passed the examination by the Trademark Office, becoming a registered trademark. R is the abbreviation of English registration. When used as a trademark, it means a registered trademark.

A registered trademark is exclusive, exclusive and unique. It belongs to the owner of the registered trademark and is protected by law. In the case that the trademark has not yet become a registered trademark, marking it with "TM" is to tell the public that this graphic or text is used as a "trademark" of goods or services, not as a name or advertisement.
