There is no possibility for any form of dialogue between the applicant and the ISA on the content of the ISR and/or the WO-ISA. However, the applicant has the right to submit to the IB amendments to the claims pursuant to Article 19 PCT, as well as informal written comments on the WO-ISA. Moreover, the applicant may consider filing a demand for international preliminary examination under Chapter II PCT (see points 300 ff).
