According to Article 40 of the Trademark Law, the validity period of each renewal registration is ten years, counting from the day after the last expiration of the trademark.

At present, there are two ways to submit Chinese trademark renewal application: 1. Paper submission; 2. Electronic submission. The difference between the two is that the certificate issued after paper submission is a paper document, and the official electronic submission no longer issues a paper document, which has the same legal effect.

Documents required for trademark renewal:

(1) If the renewal is submitted in paper form, and if it is submitted by an entrusted agency, the following originals shall be provided:

1. The original application for renewal with the official seal of the applicant in duplicate, with a total of *** 1 page;

2. The original power of attorney stamped with the official seal of the applicant is in duplicate, with a total of *** 1 page;

3. The original business license stamped with the official seal of the applicant is 1 copy.

(2) color scanned copies of the following documents are required to update the electronic submission application:

1. scanned power of attorney stamped with the official seal of the applicant, *** 1 page;

2. 1 copy of the business license stamped with the official seal of the applicant.
