I have entered the European phase late and have to pay several fees for further processing. Will they be automatically rejected by the double-payment validation functionality?

The functionality only rejects double payments of fees that are payable only once in the proceedings, e.g. the filing fee or the third/fourth/fifth/etc. renewal fee. Fees that can be paid several times during the proceedings, such as the fee for further processing or the additional search fee in the event of non-unity, are excluded from double-payment validation.
