Hello, from the trademark point of view, it is not possible, because the other party also obtained the trademark right reasonably and legally, and the category is different. Therefore, if you don't want him to use your trademark, you can only raise trademark objections during his announcement period if the trademark he applied for has not been announced. If he is successfully registered, you can file a trademark dispute from the date of his successful registration.
