If, during the period for requesting further processing, designation fees are paid without an additional sum sufficient to cover the amount of the further processing fee, it is first necessary to establish how many designation fees including the further processing fee are covered by the total sum paid for that purpose. The applicant must then be invited, pursuant to Art. 6(2) RFees, first sentence, RFees, to inform the EPO for which contracting states the designation fees plus further processing fee are to be used (see J 23/82, mutatis mutandis). For the subsequent procedure, see A‑III, 11.3.7.
