In the case of a supplementary European search report according to Art. 157(2)(a), it is also permissible under certain circumstances to have no documents at all cited on the supplementary European search report (see IV, 2.5). In such cases, the expression "No further relevant documents disclosed" will appear in the search report. However, in such cases, the search opinion (if applicable, see XII, 8) will give an opinion on the patentability of the claimed invention over the state of the art cited in the International Search Report (XII, 1.1).
