TM is the abbreviation of English trademark. The trademark or LOGO under review can be added with the word TM. Just two letters are enough. It can be typed in the upper right corner or the lower right corner. There is no hard and fast rule for this. But you don’t have to put this sign, there is no mandatory requirement, just write it if you want to.

Some people write TM on trademarks that have not been submitted for application. If the industrial and commercial department investigates, those who are fined will have nothing to say, so it is best not to write it before submitting the application.

After getting the trademark registration certificate, you can change the TM to the "?" pattern or the Chinese character "registered trademark". There is no mandatory requirement to write this down.
