First of all, whether the trademark application is successful depends mainly on three factors: 1. Whether the trademark application is illegal or not; 2. Whether it is significant; 3. Whether it conflicts with other people's prior trademarks. Through these three aspects of examination, the application for trademark will be announced in the first instance. So as long as your trademark conflicts with the above three conditions, then your trademark may be rejected.

The trademark rejection review was unsuccessful. If it is because the trademark application violates the prohibition clause, then I suggest you give it up directly. Because even administrative litigation can't be won. And this must be the dereliction of duty of the agency at that time. If the trademark is rejected for the latter two reasons, and the rejection review is unsuccessful, we can analyze the reasons for the rejection and let a professional agency conduct administrative litigation on the trademark, and there may be a glimmer of hope. Ninghai trademark is quite professional in dealing with trademark administrative litigation, so you can try it.
