How can I file an automatic debit order for fees payable in the international phase?

You can do this via EPO Online Filing, Online Filing 2.0, PCT-SAFE or ePCT, using Form PCT/RO/101, Form PCT/IPEA/401 or PCT-SFD or via Central Fee Payment (under Automatic debiting management) in Online services. A separate section in these tools allows you to select automatic debiting as your means of payment.
