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.
