TM next to a commodity trademark is the abbreviation of "trademark", indicating that the trademark has been accepted by the Trademark Office of the State Administration for Industry and Commerce, but it has not been formally registered. Once the trademark published by the General Administration has no objection from other enterprises, it can be formally registered after it is officially recognized, and the circled "R" is marked next to the commodity trademark, so other enterprises can no longer use the trademark and can be formally protected by law.
