How long does it usually take to apply for a design patent and get an authorization certificate? Can I get the authorization notice on the patent website?

If the annual registration fee is not corrected and paid in time, the patent certificate can be obtained within more than four months at the earliest.

I can't find the authorization notice online because I haven't paid the fee yet.

The time from obtaining the authorization notice to obtaining the patent certificate depends on the time of payment, and the patent certificate will be received about two and a half months after payment.
