For the purposes of Art. 123(2), the documents as originally filed are those originally filed in the PCT phase (normally published as a WO publication), a copy of which can always be obtained from the International Bureau. Therefore amendments made during the PCT phase (including amended, substitute or rectified sheets, even if attached to the WO publication) or upon entry into the regional phase before the EPO must, if maintained in the European phase, fulfil the requirements of Art. 123(2), and all such amendments must be carefully considered.
