What if the electronic patent application has been signed, but the certificate has expired when it is sent? (The certificate has not expired, it is newly updated)

Find out whether there is a 002 certificate on the electronic application website. If all certificates have expiration dates, select the corresponding certificate in the upper right corner of Browser-Tools-Internet Options-Content-Certificates. Double-click to view the expiration date of the certificate. If the service life has exceeded, you can send a paper certificate to China National Intellectual Property Administration to apply for downloading again. The process will take about 15 days, and the certificate number will become 002.
