2.10 Subject-matter excluded from search 

The examiner may exclude certain subject-matter from the search. These exclusions may result from the international application including subject-matter which the EPO as ISA is not required to deal with (see GL/PCT‑EPO B‑VIII, 2). They may also arise because the description, claims or drawings fail to meet a requirement, such as clarity or support of the claims by the description, to such an extent that no meaningful search can be carried out for all or some of the claims (see GL/PCT‑EPO B‑VIII, 3).
