In China,

The R in the circle is the initial letter of the English register registration.

Registered trademarks have exclusiveness, exclusiveness and uniqueness. They belong to the registered trademark owners. They are monopolized by the law and are protected by law. No enterprise or individual is allowed to use it without registered trademark owner. Otherwise, it will be liable for infringement.

The use of TM is the meaning of the trademark symbol, that is, the words, graphics or symbols that mark TM are trademarks, but they are not necessarily registered (unregistered without legal protection).

TM is the abbreviation of English trademark.

TM is the abbreviation of TRADEMARK. American trademark usually adds TM, not necessarily a registered trademark.

R is the abbreviation of REGISTER, used in trademark means the meaning of registered trademark. The Trademark Law of China stipulates that the use of registered trademarks can mark "registered trademarks" or "registration marks" on commodities, commodity packages, manuals or other attachments.

Registration marks include (note plus) and (R plus 0).

The use of registration marks should be marked in the upper right corner or the lower right corner of the trade mark.
