Can the lost patent certificate be reissued?

Legal analysis: Under normal circumstances, the lost patent certificate cannot be reissued, but if the certificate is lost due to the reasons of the Patent Office, you can apply for a replacement.

Legal basis: Article 1 of the Patent Examination Guide, correction of printing errors of patent certificates. When there is a typographical error in the patent certificate, the patentee may return the certificate and request the Patent Office to correct it. If the patent office verifies that it is a typographical error, it shall correct it and issue a replacement card to the patentee. The original certificate records the word "changed" and then stores it in the patent application document. If the patent certificate is lost, it will not be reissued unless it is caused by the Patent Office.
