5.2 Due date for specific fees
The fee for grant and publishing falls due on notification of the communication under Rule 71(3) requesting that this fee be paid. Under Rule 71(4), the same applies for claims fees added during the procedure to those that were already paid under Rule 45(1) and Rule 45(2) or Rule 162(1) and Rule 162(2) (see A‑X, 7.3.2).
