After paying the registration fee for two invention patents, the case status is: pending announcement and pending announcement. What do these two states mean?

Pending announcement and waiting announcement are both a state after unpaid patents are authorized to pay patent registration fees. Waiting for the registration announcement is the first step before waiting for the announcement. The time for waiting for the registration announcement is relatively short, about two to three days, which proves that the registration fee has been successfully deducted by the National Information Bureau. Waiting for the announcement is a process of certification, which takes one month to one and a half months. When the certificate is completed, it will become the maintenance of the patent right. The certificate will be sent by registered mail of the State Knowledge Bureau, and the logistics progress can be viewed in the post information column of the State Knowledge Bureau of official website.
