Can I make bank transfer payments in Online Filing / Online Filing 2.0 / ePCT?

No. In Online Filing / Online Filing 2.0 you can indicate the payment method you intend to use. However, to make the actual bank payment, you first need to go to Central Fee Payment and submit a payment order to obtain your unique payment reference EPOxxxxxxxx. Once you have received it, you then need to make the transfer from your bank to the EPO’s bank account.
