Incorporation by reference of missing parts and elements
If the receiving Office has granted a request for incorporation by reference under Rules 4.18 and 20.6 PCT but the EPO as IPEA does not consider the relevant part(s) and/or element(s) completely contained in the priority application, it will indicate so in the IPER (see points 2.4.001 ff).
