The date on which the amount is actually entered in the European Patent Organisation's bank account is considered as the date on which payment is made. It is therefore also possible for the day following the inpayment or transfer to be considered as the date on which payment is made or an even later date in the event of delays within the bank or in the post. However, payment may still be considered to have been made in due time, despite being paid late, if the inpayment or transfer has been effected before expiry of the time limit for payment in a Contracting State and, where appropriate, a surcharge has been paid (see XI, 6).
