1.2 Opinions on matters relating to limitation of the search 

Occasionally, matters of substantive examination other than novelty or inventive step have a direct bearing on how the search is carried out and may result in its limitation. The search division's opinions on theses matters are likewise subject to review by the examining division (see T 178/84 and T 631/97, and B‑II, 4.2(iii) and B‑XI, 1.2), in particular in the light of the applicant's reply to the search opinion (see B‑XI, 8).

See B‑VII (Unity of invention) and B‑VIII (Subject-matter to be excluded from the search) for examples.
