Can the applicant and inventor of the patent be changed before the certificate is issued? If yes, is the certificate printed according to the changed information?

You can change it after receiving the authorization notice, but the time is tight. You can not pay the authorization fee first, and then pay the authorization law on the last day of the authorization time, which will delay the time. The replacement time is generally 2 months. Otherwise, your authorization fee has been paid. Although it has been changed, the certificate will not change.
