If the patent cannot be restored after expiration, can I reapply? Will the certificate come down?

Only when a patent certificate is issued will there be a patent right. Before that, it was a patent application, not a patent.

If the patent right expires and cannot be restored because the annual fee has not been paid, it cannot be re-applied because it is not novel.

If the patent application cannot be resumed after the interruption, a new application for utility model or design may be made, but the published application for invention cannot be re-applied, which is not novel.
