- In this opposition appeal, the patentee did not submit auxiliary requests before the OD and did not request oral proceedings. The OD revoked the patent only on the ground of lack of novelty of one claim over D2, without holding oral proceedings. In appeal, the patentee defends that the claims as granted are novel over D2, and also over D1 and D3, with success. The Board considers the claims as granted novel and remits the case. The opponent appears overall unhappy with the procedural course of action. The opponent challenges admissibility of the appeal, protests against the remittal, and requests an apportionment of costs.
- As to admissibility, the Board: "In a case such as the present one, where the appeal lies against a decision based on a sole ground (lack of novelty) a statement of grounds is sufficiently substantiated in the sense of Rule 99(2) EPC if it addresses that sole ground in a manner for the Board and the other party to understand why the Appellant considers the decision to be incorrect." "The Respondent-Opponent has rather argued that the Appellant [patentee] in their statement of grounds should have dealt with all grounds raised in opposition. This view however has neither a basis in the Convention nor is it supported by jurisprudence."
- As to the remittal: "The Respondent-Opponent requests the Board to make a final decision rather than remit the case to the Opposition Division." "In the present case all grounds of opposition under Article 100 EPC had been raised against all of the claims of the patent, based on various citations. The Opposition Division, however, issued its decision immediately, without oral proceedings, based only on the single ground of lack of novelty of claim 15 over a single document [D2, see r.3]. "
- " In the light of the above, the Board considers that having a final decision without remittal would largely exceed the primary function of the appeal proceedings as judicial review of a first instance decision to such an extent that outweighs, in the present case, the public interest for procedural economy and the legitimate wish of the Respondent-Opponent to have such decision made by the Board."
- As to the request for apportionment of costs (i.e. that the patentee pays the costs to be made by the opponent in the future second proceedings before the OD): the Board sees no ground.
- The fact that patentee dealt with all of opponents attacks before the OD " only by argument, without submitting auxiliary requests and without requesting oral proceedings, is a legitimate defence against an opposition, though it runs the calculated risk of an immediate contrary decision."
- " Thus, the Appellant-Proprietor had no particular obligation to request oral proceedings before the Opposition Division. Their right to appeal or to file further requests on appeal is not affected by the mere fact that they did not request oral proceedings [before the OD]. The Board fails to see any legal basis for the implied assertion of the Respondent that the rights of the Appellant-Proprietor in the appeal proceedings are somehow more restricted because they did not request oral proceedings."

Reasons for the Decision
1. Admissibility of the appeal
1.1 The Respondent-Opponent objects that the statement of grounds only addresses novelty of claim 15 and is therefore not a complete case in the sense of Article 12(2) RPBA. On this ground the appeal is, according to the Respondent, inadmissible.
1.2 Concerning the disputed aspect of the admissibility, the extent of the required reasoning and sufficient substantiation, this is governed by Article 108 and Rule 99(2) EPC. The examination of the question whether the requirements of Article 108 EPC, third sentence in combination with Rule 99(2) EPC are met is made on the basis of the contents of both the statement of grounds of appeal and of the decision under appeal, T 162/97, see Case Law of the Boards of Appeal, 2016, 8th. edition (CLBA), IV.E.2.6.3. In a case such as the present one, where the appeal lies against a decision based on a sole ground (lack of novelty) a statement of grounds is sufficiently substantiated in the sense of Rule 99(2) EPC if it addresses that sole ground in a manner for the Board and the other party to understand why the Appellant considers the decision to be incorrect. That the present statement of grounds addresses the sole ground for revocation, and in sufficient detail, is undoubtedly the case. Nor has it been argued that this would not be so.
1.3 The Respondent-Opponent has rather argued that the Appellant in their statement of grounds should have dealt with all grounds raised in opposition. This view however has neither a basis in the Convention nor is it supported by jurisprudence. Neither of the two decisions cited by the Respondent is indeed concerned with the question of admissibility of an appeal. T 396/98 deals with the issue of the extent to which an opposition division's decision is binding on the corresponding appeal board, see Reasons, point 2 - i.e. whether the board can also review findings of the opposition division that were in favour of the appellant party-, which is not related to the question of admissibility of the appeal. T 240/04, on the other hand concerns the question of admittance of an auxiliary request, see Reasons points 16.1-16.3.
1.4 As otherwise all formal requirements of Article 108 and Rule 99 EPC are met, the Board concludes that the appeal is admissible.
