Can the original patent be reissued if it is lost?

Legal analysis: Under normal circumstances, the original patent certificate cannot be reissued after it is lost, but if it is lost because of the Patent Office, you can apply for a replacement.

Legal basis: Patent Examination Guide 1.2.4 Patent certificate printing error correction. 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.
