In the following cases, the search report, the declaration replacing it, or the incomplete or partial search report will indicate whether the subject of the search was restricted and which claims have or have not been searched:

(i)claims above the number of fifteen for which no additional fee has been paid (see B‑III, 3.4). The claims not searched are identified. This only applies to European and supplementary European search reports;[Rule 45(1); Rule 45(3); Rule 162(1); Rule 162(4); ]

(ii)lack of unity of invention (see B‑VII). The different inventions must be mentioned by indicating their subject-matter and the claims relating thereto (in part or in full; see Rule 44(2). For the partial search report (see B‑VII, 1.1), an indication is made that it has been established for the invention first mentioned in the claims. This applies to a priori lack of unity and to a posteriori lack of unity. For the search report which will be drawn up for all those inventions in respect of which search fees have been paid, the different inventions (and corresponding claims in full or in part) which have been searched are indicated in the search report;[Rule 64(1); ]

(iii)claims in respect of which a meaningful search cannot or only an incomplete search can be carried out (see B‑VIII). A declaration is made either:[Rule 63; Art. 52(2); Art. 53; ]

In both cases (a) and (b), the reasons for not carrying out or restricting the search must be indicated (for example: subject-matter not patentable; insufficiently clear claims). If necessary, full reasoning is provided in the search opinion; see B‑VIII, 3.3, for the content of the EESR in these cases.

(iv)claims in respect of which a search was not carried out due to non-compliance with Rule 43(2) (see B‑VIII, 4.2).[Rule 62a; ]
