2.2 Search division has more than one member 

A special search division consisting of two, or possibly even three, members may be formed where the nature of the invention makes it necessary to search in very different specialist fields, for example because the "person skilled in the art" in the relevant technical field has to be regarded as being more than one person (see G‑VII, 3).

This may also happen where subject-matter covering different technical fields is found to lack unity.

When the search division is enlarged this way, all the documents found in the various technical fields by its different members are included in the same search report. However, only one member draws up the search opinion, albeit in consultation with the members with expertise in the other technical fields where necessary.
