Title of application: -
Applicant name: Siemens
Opponent name: Kernforschungszentrum Karlsruhe
Board: EBA
Headnote: Unity of invention (Article 82 EPC) does not come under the requirements that a European patent and the invention to which it relates must meet under Article 102(3) EPC when the patent is maintained in amended form. It is consequently irrelevant in opposition proceedings that the European patent as granted or amended does not meet the requirement of unity.
Relevant legal provisions:
European Patent Convention 1973 Art 82
European Patent Convention 1973 Art 102(3)
European Patent Convention 1973 R 61a
Keywords: Unity in opposition - legally irrelevant
