In China, the TM on the trademark also has its own special meaning. In fact, the TM mark does not protect the trademark. It is different from R. TM means that the trademark has been applied to the National Trademark Office, and The National Trademark Office has also issued a "Notice of Acceptance" and entered the opposition period. This will prevent others from filing repeated applications and also indicates that existing trademark holders have priority to use the trademark. The circle R indicates "registered trademark", which means that the trademark has been applied for registration at the National Trademark Office and has been reviewed and approved by the Trademark Office to become a registered trademark. The R in the circle is the first letter of English register. A registered trademark has the characteristics of exclusivity, exclusivity, and uniqueness. It is owned exclusively by 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 infringement liability. TM means the trademark symbol, that is, the words, graphics or symbols marked with TM are trademarks, but they are not necessarily registered (unregistered ones are not protected by law). TM is the abbreviation of English trademark.
