Xiaokang has the answer for you:

After the trademark registration certificate is lost, it is recommended to reissue it as soon as possible to avoid affecting the subsequent trademark business. There are two ways to reissue the trademark registration certificate:

The applicant can handle the application through the relevant acceptance window or entrust a trademark agency registered with the Trademark Office to handle the application.

Normally, the State Intellectual Property Office will issue a new registration certificate about 2-3 months after receiving an application for a trademark reissue.

Currently, there are two ways to submit an application for a Chinese trademark reissue trademark registration certificate: 1. Paper submission; 2. Electronic submission. The difference between the two is that the certificate issued after paper submission is a paper document. For electronically submitted applications, the official will no longer issue paper certificates. The legal effect of both is the same.

The Kangxin IP platform has launched the "reissue certificate" function, which supports online applications for reissue of registration certificates and reissue of change/transfer/renewal certificates.
