Partial European search report 

If the search division considers that the European application does not comply with the requirement of unity of invention (see F‑V, 1), it must search it, and draw up the partial European search report under Rule 64(1), for those parts of the application which relate to the invention (or group of inventions forming unity) first mentioned in the claims (see F‑V, 4.4F‑V, 3.4). The partial European search report is supplemented with a specification of the separate inventions.

With regard to the search opinion in cases of a lack of unity of invention, see B‑XI, 5.
