Trademarks are not case-sensitive, because as long as you register lowercase text or lowercase English, it is impossible for someone else to successfully register the uppercase English version, because this will constitute a similar trademark. Under normal circumstances, if you register a word trademark, you do not need to register it together, and it is impossible to register it.

Identical word trademarks means that the trademarks use the same language, and the text composition and arrangement order are exactly the same. If there are slight differences between two trademarks due to the difference in fonts, capitalization of letters, or the arrangement of words in horizontal or vertical format, they will still be determined to be the same trademark.

Expansion:

The difference between English and Chinese capital letters in trademark registration, there is the problem of the same trademark. When it comes to the same trademark, the so-called identical trademark means that the elements that constitute the trademark are exactly the same. There is no or subtle difference between the trademarks as a whole. Identical word trademarks refer to trademarks that use the same language and have the same font, pronunciation, and meaning, and are generally regarded as trademarks with the same words.
