T 2313/15 - Only arguments before OD

Key points

  • 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.


2. Background

The invention is concerned with the production of frothed liquid from the combination of a diluent and a soluble ingredient. The invention is generally aimed at providing a simple and low cost method and device, without involving the use of motor-driven whipping means or a pressurized chamber, see specification paragraph [0009]. With this aim, a soluble ingredient (powder or liquid concentrate) is dosed into a mixing chamber. The force of a continuous jet of diluent injected into the mixing chamber is used to form a swirling layer of liquid along an internal wall of the chamber, the jet being further so sized and oriented that the formed layer of liquid is also impacted on its surface by the incoming jet. As a result the powder or concentrate is dissolved and froth is produced. The liquid flow exiting the chamber through the bottom outlet is controlled to prevent the liquid from leaving the chamber too quickly, since insufficient liquid quantity inside the chamber would not allow the development of the appropriate swirling layer of liquid, see paragraphs [0010]-[0013] and [0051] of the specification.

3. Novelty of granted claim 15.

The Appellant-Proprietor contests the findings of the Opposition Division that the subject-matter of granted claim 15 is not new over D2. The Respondent-Opponent contends that not only was the division right to find lack of novelty over D2 but that the claimed subject-matter also lacks novelty over D1 and D3/D3b, as already argued in opposition.

3.1 Document D2

[...]

3.1.6 The Board thus concludes that the subject-matter of claim 15 is new over D2.

3.2 Documents D1 and D3/D3b

[...]

3.2.3 In view of the above, the Board holds that the subject-matter of granted claim 15 is new over the cited prior art, D1, D2 and D3/D3b.

3.3 Remittal

3.3.1 The Respondent-Opponent requests the Board to make a final decision rather than remit the case to the Opposition Division. Indeed, as correctly noted by the Respondent-Opponent, there is no absolute right to have an issue decided at two instances and the general interest in conclusion of proceedings within a reasonable time frame or other criteria may sometimes weigh more heavily than the interest of one or more of the parties, cf. CLBA IV.E.7.2.1 or II.E.7.6. However, the decision remains at the discretion of the Board which must weigh up all relevant factors on a case by case basis.

3.3.2 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. For the Board to decide all the remaining issues it would effectively be carrying out the greater part of the task entrusted to the first instance and it would then do so in a rather different framework to that in which it had decided novelty. This would be alien to an appeal board's primary role to adjudicate on the correctness of decisions by departments of first instance. Nor does it seem particularly fair to the Board that the Appellant Proprietor should stand to lose all in what is then effectively a single instance procedure. Finally, having stated in its communication its intention to remit should claim 15 of one of the requests be found novel, the Board does not consider itself in a position to decide all of the remaining issues, nor is the Appellant Proprietor in a position to defend its position on all points.

3.3.3 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.

3.3.4 The Board thus decides in the exercise of its discretionary power under Article 111(1) EPC to remit the case to the department of first instance for further prosecution.

4. Request for a different apportionment of costs.

Under Article 104(1) EPC, in opposition proceedings each party must, as a rule, meet the costs it has incurred, unless reasons of equity justify to order otherwise.

4.1 The Respondent-Opponent requests an award of costs in respect of the additional expenses for a second first-instance opposition proceedings and for the present appeal proceedings, in the event that the case is remitted. The Respondent argues that the Proprietor neither requested oral proceedings nor filed auxiliary requests at first instance that could have avoided remittal and that they furthermore, in appeal, solely presented arguments and auxiliary requests in defense of novelty of claim 15, also missing a further opportunity to avoid remittal. The extra costs are thus caused by the Appellant-Proprietor's behaviour.

4.2 The Board notes that in the present case, the Proprietor in the proceedings before the opposition division dealt with all the objections raised by the Opponent in their reply to the notice of opposition. That it did so 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. 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. It cannot be known how the events would have unfolded, had oral proceedings taken place, and it cannot be known if this would have materially changed the outcome of the first-instance opposition proceedings. It is also not apparent that the present situation is financially much worse for the Respondent. It could be argued that much of the cost of a full first instance proceedings with oral proceedings and multiple auxiliary requests was spared them.

Nor does the Board consider it equitable to impute to the Appellant-Proprietor the fact that the Opposition Division chose to decide the case on the basis of only one of the various issues raised and without summoning to oral proceedings (and was within its rights to do so). Likewise the decision to now remit the case upon appeal in accordance with common practice can also not be imputed to the successful Appellant. Finally, that upon appeal the Appellant argued only against novelty over D2 as sole ground for revocation is not in any way reprehensible as it is all they are required to do, as noted above.

4.3 The main argument of the Respondent was directed at the fact that generally, costs could have been avoided, if Appellant had conducted the proceedings properly and diligently. It was not argued that possibly different conclusions might also be justified for the two distinct cost items due to their different character (first second-instance proceedings and second first-instance proceedings), the two cost items were treated by Respondent as a single cost burden. Given that the Board does not accept Respondent's arguments for the reasons given above, i.e. that the Board does not see any reproachable conduct by Appellant at all, it is not necessary for the Board to address whether Respondent's arguments were indeed equally applicable to these two cost items, in spite of their different character.

4.4 In conclusion, it does not appear equitable to the Board that the Appellant-Proprietor should bear the costs for consequences that derive from discretionary procedural decisions on the part of the Opposition Division, of the Board of Appeal or from circumstances of the case that are not demonstrably the result of an abuse or lack of due care on the part of the Appellant-Proprietor. The Board thus decides not to order a different apportionment of costs pursuant to Article 104(1) EPC.
Order
For these reasons it is decided that:
1. The decision under appeal is set aside.
2. The case is remitted to the Opposition Division for further prosecution.
