After the Trademark Office receives the application and determines that the procedures are complete and the filling is standardized after formal review, it will usually send the "Notice of Acceptance" to the applicant by registered mail in about three months. If the trademark registration application is entrusted to a trademark agency, the Trademark Office will mail the "Notification of Acceptance" to the trademark agency, which will usually be received within half a month. The "Notification of Acceptance" only indicates that the trademark registration application has been accepted by the Trademark Office, but does not indicate that the application has been approved.
