article 37 of the regulations for the implementation of the trademark law of the people's Republic of China stipulates that if a registered trademark is used, a "registered trademark" or a registered mark may be marked on the commodity, its packaging, instructions or other attachments. Registration marks include (note plus ) and (r plus ). The use of registration marks shall be marked in the upper right corner or the lower right corner of the trademark.

1. TM on a TRADEMARK has its special meaning. TM is the abbreviation of trademark, and the TM logo does not protect the trademark. It is different from R. TM means that the trademark has been applied to the State Trademark Office, and the State Trademark Office has issued a Notice of Acceptance, which has entered an objection period. This can prevent others from filing repeated applications, and also means that existing trademark holders have the priority to use it.

2. The circle R is the mark of "registered trademark", which means that the trademark has been registered in the State Trademark Office and passed the examination by the Trademark Office, and has become a registered trademark. A registered trademark has the characteristics of exclusiveness, exclusiveness and uniqueness. It belongs to the owner of the registered trademark and is protected by law. No enterprise or individual may use it without the permission or authorization of the owner of the registered trademark, otherwise it will bear the tort liability. R in the circle is the initial letter of English register registration.

TM means trademark symbol, that is, words, graphics or symbols marked with TM are trademarks, but they may not be registered (unregistered ones are not protected by law).
