How to calculate the time for sending trademark registration review materials

Because it is difficult to collect materials, we only send the review application materials and evidence on the last day of processing. We use EMS Express.

Now I would like to ask how to calculate the time for sending this kind of mail? Will it be considered expired? If it is not overdue, how long will it take to receive the acceptance notice?

1. According to Article 53 of the "Trademark Review and Adjudication Rules", the date of the documents or materials submitted by the party to the Trademark Review and Adjudication Board shall be the date of submission if submitted directly; if it is mailed, the date of submission shall be the date of submission. The postmark date shall prevail; if the postmark date is unclear or there is no postmark, the actual date of receipt by the Trademark Review and Adjudication Board shall prevail, unless the party concerned can provide evidence of the actual postmark date. 2. Our committee will review the case after the expiration of three months after the parties submit the application materials and supplementary materials, and the Fawen Department will subsequently issue an acceptance notice.
