"TM" is commonly seen in foreign trademarks. It is the abbreviation of the English "trade mark". The Chinese meaning of "trade mark" is "commercial mark", so "TM" means "trademark". It Its function is to tell people that the graphics or words marked on it are the trademarks of the goods or services, not the names or advertisements.
Chinese law currently has no relevant provisions on the use of the “TM” mark. The use of the word "TM" has no correspondence with whether the trademark has applied for registration, whether it has been accepted, whether it has received preliminary notice, whether it has been opposed, or whether it has been approved for registration. It is just a sign voluntarily used by the trademark owner, and it does not mean that a sign marked with "TM" must be a trademark.
Extended information:
The TM on the trademark has its own special meaning. The TM mark does not protect the trademark. It is different from R. TM is the abbreviation of TradeMark, which includes both registration and registration. Trademark R also includes direct use of unregistered trademarks that have not been approved by the Trademark Office.
Trademark annotation TM can play a certain protective role. However, if the trademark has not been approved and registered by the Trademark Office, it will not be protected by law. This is only when the unregistered trademark reaches a certain level of popularity. Only by doing so can we obtain legal protection to a certain extent
