I lost my utility model patent certificate, but I need a copy. What should I do?

The patent certificate is lost and cannot be reissued.

Keep electronic copies of paper reminders of important documents.

If it is necessary to prove the legal status of a patent, China National Intellectual Property Administration may be required to issue a copy of the patent register.

Copy of patent registration

China National Intellectual Property Administration established a patent register when granting the patent right. When the patent right is granted, the contents recorded in the patent register and the patent certificate are consistent and have the same legal effect.

Request for required materials:

In order to process the copy of the patent register, a copy of the document signed and sealed by the requester is needed to process the request. The "Request for Copying Documents" can be found in "Workspace, Form Download" on China National Intellectual Property Administration's website.
