GA C IV 2 Scope and limitations of the SIS

280
The scope of the search conducted by the EPO as SISA, i.e. the documentation searched, is the same as for any international search carried out by the EPO as ISA (see point 220).
281
The SIS is conducted on the international application as originally filed, and neither amendments filed under Article 19 and/or 34 PCT nor informal comments will be taken into account.
R. 45bis.5(b) PCT
282
If the ISR is available at the time the SIS is carried out, it will be taken into account. Prior-art documents mentioned in the ISR are re-cited in the SISR only if the EPO qualifies their relevance differently. 
283
The EPO conducts a maximum of 700 supplementary searches per year. 
284
The limitations related to subject-matter set out in Annex C to the Agreement EPO-WIPO apply both where the EPO acts as ISA and where it acts as SISA (see points 257 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 253 ff). As to particulars of the procedure in case of a missing sequence listing and non-unity, please refer to points 288 and 292.
285
Furthermore, the EPO acting as SISA may decide not to carry out a search on claims that were not searched by the ISA either. However, if the EPO as ISA had searched the claims concerned, it will also search these claims if it acts as SISA. 
R. 45bis.5(c), (d), (e) PCT
