The handling fee is collected by the EPO as International Preliminary Examining Authority (IPEA/EP) for the benefit of the IB and its amount is fixed by the IB. It is to be paid within one month from the date on which the demand (Form PCT/IPEA/401) was submitted or within 22 months from the priority date, whichever time limit expires later. The amount payable is the amount applicable on the date of payment. For any reductions that may apply, see GL/PCT‑EPO A‑III, 8.3.[Art. 31(5); Rule 57; GL/ISPE 22.44; OJ EPO 2018, A101; ]

If the handling fee is not fully paid within the prescribed time limit, the IPEA/EP proceeds as described under GL/PCT‑EPO A‑III, 7.5.
