Judging from the ruling documents of the Trademark Review and Adjudication Board, except for category 25, it takes about 1 year, and almost all other categories take about 6-8 months.

Supplement: The applicant may, within 15 days from the date of receiving the notice of rejection, ruling or revocation, request the Trademark Review and Adjudication Board for reexamination. If there are special reasons, you can apply for an extension before the expiration, and the extension time is 30 days, but you need to submit evidence of the extension, such as the certificate of the post office or neighborhood Committee. Prove that it is overdue to receive the notice of rejection, ruling or revocation.
