Generally speaking, different subcategories of the same category do not interfere with each other, that is, different subcategories of the same category can register the same name. In this case, it is generally necessary to exclude whether similar goods are involved in these small categories. If similar goods are involved, it is necessary to judge carefully, and it may be judged as the same category, which may lead to the inability to register. This is also the key to the success of trademark registration in the same category and different subcategories! You should also be careful when it comes to famous trademarks. What is a famous trademark? The so-called well-known trademark refers to a registered trademark with high market reputation and commercial value that is well known to the relevant public and recognized according to law. For well-known trademarks, this problem of avoiding subclasses is even more alarming. Inadvertently, the trademark will be refuted. This also explains whether the trademarks of the same category and different subclasses can be registered successfully!
