Headnote: I. Assessment of the inventive step of a chemical invention (in this case microcapsules for carbonless copying paper) has to be preceded by determination of the technical problem based on objective criteria. If the prior art cited shows that this problem has to be regarded as the selection of another novel agent from a known class (polyureas), then it can generally also be subsequently argued that the problem consists in selecting a surprisingly improved agent.
II. In an appropriate case, such a restatement of the problem may be possible during the course of an appeal; the supporting evidence is, after examination of the particular case, to be regarded as submitted in due time within the meaning of Art. 114(2) EPC, if it is submitted together with the Statement of Grounds for the appeal.
