As for the same category you mentioned, there are several identical trademarks. Possible situations are:

1. There are identical trademarks in similar groups: the applicant is the same, or the applicants are different, but there is only one valid trademark, and the others are rejected, invalid or pending trial.

2. Although they are all in the same category, the similar groups protected by these same trademarks are different, so they can all be applied for registration.
