The European Patent Convention

(2)

If the statement under paragraph 1 is not filed in due time, or if it is not sufficient to overcome the deficiency noted under paragraph 1, the European Patent Office shall either issue a reasoned declaration stating that the European patent application fails to such an extent to comply with this Convention that it is impossible to carry out a meaningful search regarding the state of the art on the basis of all or some of the subject-matter claimed or, as far as is practicable, draw up a partial search report. The reasoned declaration or the partial search report shall be considered, for the purposes of subsequent proceedings, as the European search report.
