The substantive examination is conducted in the same way as with European applications. Where the EPO was the International Preliminary Examining Authority, the international preliminary examination will normally have been carried out by the examiner responsible for examining the related Euro-PCT application.
The application to be examined will be accompanied by an international preliminary examination report drawn up in one of the official languages of the EPO. New documents in the original language may be attached in annex to the report (Art. 36(3)(a) PCT and Rule 70.16 PCT). The application will also be accompanied by a translation of the annexes, transmitted by the applicant, in the same language into which the international preliminary examination report was translated (Art. 36(3)(b) PCT).
