I applied for a patent for utility model electronically, and the patent is still being accepted. I lost my digital certificate due to personal problems. What should I do?

If the digital certificate is accidentally lost due to computer reloading or other reasons, you can log on to the patent electronic application website, click on the relevant information column to download the electronic applicant's opinion statement on registration affairs, fill in the form as required, and mail the paper form and relevant supporting documents to the Patent Office. After the materials are approved, the relevant personnel will handle the replacement procedures for the users. Please download the certificate and back it up in time, so as to avoid the loss of digital certificate affecting the system use.
