Will the patent office take the initiative to refund?

Guide to Patent Examination Chapter II: Patent Office Voluntary Refund of Patent Fees

Once the following circumstances are verified, the Patent Office shall take the initiative to return them.

(1) The substantive examination fee paid before the Patent Office issues the notice that the application for a patent for invention enters the substantive examination stage after the declaration that the patent application is deemed to be withdrawn or withdrawn is approved.

(two) the annual fee paid after the announcement of the decision to terminate the patent right or declare the patent right invalid.

(3) If the Patent Office decides not to restore the right after the approval procedure of the right restoration request is started, the party concerned has paid the right restoration request fee and related expenses.
