"TM" is the abbreviation of "trademark" in English, and "R" is the abbreviation of "register" in English. "TM" and "R" both play a suggestive role. Usually, they all appear in the upper right corner or lower right corner of some signs. "TM" indicates that the sign is used as a trademark, while "R" indicates that the sign is already a registered trademark and enjoys the exclusive right to use the trademark.

China's laws clearly stipulate the use of R, but not the use and management of TM. As long as the operator wants to inform others that a certain mark is used as a trademark, he can use the "TM" mark regardless of whether the mark applies for trademark registration. However, it must be clear that "R", as a special symbol of a registered trademark, can only be marked after the trademark is officially registered, otherwise it will be a counterfeit trademark and will be punished. If a trademark with "TM" logo is the same as or similar to a registered trademark, it will constitute infringement of other trademarks and will also be punished. Also, if the trademark with the "TM" logo is not registered in time, and other enterprises scramble to register the trademark, then after the registered trademark of others is officially registered, this enterprise can no longer use the trademark with the "TM" logo, otherwise it will constitute infringement.
