A copy of a patent certificate can only be applied if the certificate is issued and there are multiple patentees. You can't apply again after you get the certificate.
You can ask for a copy of the patent register. A copy of the patent register has the legal effect of proving the ownership of the patent right at that time.
3. The patent certificate will not be reissued.
Lost and other reasons will not be reissued.
After obtaining the patent certificate, change the patentee and apply for a copy of the patent register.

Supplementary answer:
1, patent ownership dispute refers to an invention that does not belong to you, but you applied for a patent, and later generations have enough evidence to prove that you obtained the invention from others before the application date. This certificate can be changed after mediation or judgment.
The ownership dispute of the patent right is that someone else applied for a patent under a pseudonym before the application date; However, the transfer after applying for a patent does not belong to this category.
2, the patent certificate is damaged, in the patent period, you can request replacement. However, the format and content of the replaced certificate are consistent with the original certificate, and the damaged patent certificate needs to be returned.
The patent office made a mistake by itself, of course, it can be corrected.
The Patent Office expressly stipulates that if the name of the patentee changes due to the transfer of the patent right or the renaming of the patentee, the patent certificate will not be replaced.
