If a trademark is rejected, the National Trademark Office will issue a "Notice of Trademark Rejection". The notice will explain the reasons for the rejection and point out the citing trademark. So, just wait for the notice to arrive and you will naturally know the reason for rejection!

If your company does not want to give up the trademark, you must start preparing materials for rejection review from now on, because you only have 15 days from the date of receiving the "Notice of Refusal Review" to write Material.

Article 32 of the Trademark Law: For a trademark that rejects the application and refuses to be announced, the Trademark Office shall notify the trademark registration applicant in writing. If the trademark registration applicant is dissatisfied, he may apply to the Trademark Review and Adjudication Board for review within fifteen days from the date of receipt of the notice. The Trademark Review and Adjudication Board will make a decision and notify the applicant in writing.
