GREP to find superscript whole word

I'd use TM/>, because in English at least I don't know any words that end in TM. Make sure you don't match, say, DEPARTMENT. Below is  an example using a character style called "superscript".

- Mark

EDIT: This will still incorrectly find some acronyms, eg. "ATM" (automatic telling machine).

Remove the \< and \> they means begining and end of word.

If you just need to find TM irrespective of whether it is superscript or not you can use the following

(?i)TM

You can remove (?i) if it's always TM and you don't need to look for cases like tm, Tm etc

If you have to look only for TM in superscript then in addition to the above grep use the find format option of the find/change dialog and select superscript as the option

I don't understand why you use \<\> in your grep statement, maybe I am missing something but as far as I can undertand it will literally search for TM enclosed in <>. But your question states you are concerned only about TM
