T 0618/23 - Pages 120-125 of the SoG do the job

Key points

• The OD decided to maintain the patent in amended form based on AR-25a. Both parties appeal.
• The Board, in machine translation: "the patent proprietor argued, among other things, that the opponent's statement of grounds of appeal, contrary to Article 12(3) of the Rules of Procedure of the Boards of Appeal, did not clearly and concisely explain why the contested decision should be set aside. Instead, it dealt with extraneous matters (such as the proceedings concerning the parallel German patent 10 2015 117 403 before the Federal Patent Court), addressed "an unmanageable number of different, partly equivalent lines of argument" and failed to provide a problem-solving approach for any of these lines of argument."
• "The Board notes, however, that the appellant has sufficiently explained, at least on pages 120 to 123 of the statement of grounds of appeal [ that had in total 134 pages], why the contested decision should be set aside and, in particular, why claim 1 of granted auxiliary request 25a, based on E7 in combination with E13, does not involve an inventive step. While the appellant's submissions are extensive, they are nevertheless sufficiently substantiated. The mere fact that the statement of grounds of appeal contains a number of irrelevant statements alongside the arguments relevant to the decision does not render the appeal inadmissible."
• In the statement of grounds (SoG), the opponent first attacked the patent as granted (p. 11), citing extensive prior art that was no longer relevant for AR-25a (as I understand it). The opponent then addressed AR-1 (p. 84) and all subsequent auxiliary requests, eventually arriving at AR-25a on p. 120.
• In the opponent’s SoG, an attack against requests ranked higher than the auxiliary request held allowable by the OD is indeed an "irrelevant statement", according to the majority line of case law (as I understand it).


• The Board first deals with the claim requests in the proprietor’s appeal and then turns to the set of claims held allowable by the OD (and contested in the opponent’s appeal)."The Board concludes that the subject matter of claim 1, starting from E7 in combination with E13 and the general technical knowledge, does not involve an inventive step."
• The Board then turns to lower-ranking requests, where novelty over E2 becomes an issue. I have not studied this part of the decision in detail.
• The patent is revoked.
