The scope of the search conducted by the EPO as SISA - i.e. the documentation searched - is the same as for any international search performed by the EPO as ISA (see point 218).
The limitations related to subject-matter set out in Annex A to the Agreement EPO-WIPO apply both where the EPO acts as ISA and where it acts as SISA (see points 253 ff). The same applies as to any other reason for non-establishment of a (full) search, i.e. complex applications, missing sequence listings and non-unity (see points 249 ff). As to particulars of the procedure in case of a missing sequence listing and non-unity, reference is made to points 284 and 288.
Further, where the EPO acts as SISA it may decide not to search claims that were not searched by the ISA. However, if the EPO, had it been the ISA for the international application, would have searched the claims concerned, it will not exercise its discretion not to search these claims if it acts as SISA.
