Hello, the trademark name is followed by a circle and r, which means registered trademark. As for A/B, it is not clear.

? Trademarks can be divided into registered trademarks and unregistered trademarks.

TM is the abbreviation of "trademark" and R is the abbreviation of "register".

TM stands for "trademark" and R stands for "registered trademark", which is an official mark. Both registered and unregistered trademarks can be marked with TM, indicating that the right holder uses the mark as a trademark.

Please don't imitate it, which will serve as a warning. However, only a trademark that has been approved and registered by the State Trademark Office and issued with a Trademark Registration Certificate can use R within the approved scope.

Goods/services that have not been registered or are beyond the approved scope of the trademark certificate cannot be marked with R..
