(1)34 Each Contracting State shall pay to the Organisation in respect of each renewal fee received for a European patent in that State an amount equal to a proportion of that fee, to be fixed by the Administrative Council; the proportion shall not exceed 75% and shall be the same for all Contracting States. However, if the said proportion corresponds to an amount which is less than a uniform minimum amount fixed by the Administrative Council, the Contracting State shall pay that minimum to the Organisation.
(2) Each Contracting State shall communicate to the Organisation such information as the Administrative Council considers to be necessary to determine the amount of these payments.
(3) The due dates for these payments shall be determined by the Administrative Council.
(4) If a payment is not remitted fully by the due date, the Contracting State shall pay interest from the due date on the amount remaining unpaid.
