Legal status can be roughly divided into three types:
The first is unstable state, such as "disclosure" and "substantive examination" of an application for a patent for invention, that is, waiting for examination or examining the ongoing situation;
The second is a relatively stable state, that is, the "authorized" state after the audit. Some patents may still be "expired", and some may be "terminated" because they have not paid the annual fee on time;
The third is a stable state, such as "withdrawal" after publicity, "deemed withdrawal" during review, "rejection" and "abandonment" after authorization, and "revocation" or "invalidation"; This case ends here, and there will be no change.
