Next to some trademarks, there is the mark "TM", which is the English abbreviation of "trademark". It does not mean that it has been registered, nor does it mean that it has applied or is related to any process, and so on.
The current trademark law does not require the use of registered trademark marks, let alone TM marks.
The use of TM trademark and R trademark only indicates users' preference, and has nothing to do with trademark law, trademark application and registration, and process.
