only if the applicant wishes such amendments to form the basis of further proceedings, any amendments made to the claims under Article 19 PCT in the form of a translation of the complete set of claims furnished in replacement of all claims originally filed (see point 245). The claims as amended under Article 19 PCT must be submitted together with, if submitted to the IB, the translated statement under Article 19(1) PCT explaining the amendments and, in every case, the translated accompanying letter under Rule 46.5(b) PCT, indicating the basis for the amendments in the application as filed, in an official language of the EPO. If a translation of the complete set of claims submitted under Article 19 PCT is not furnished or not accompanied by a translation of, if submitted to the IB, the statement under Article 19(1) PCT and, in every case, the accompanying letter under Rule 46.5(b) PCT, the amendments under Article 19 PCT will be disregarded for the further proceedings.
