Key points
- The Board, in the headnote: "The question of whether a fresh ground of opposition has been raised - and, therefore, of whether the agreement of the patentee is required - has to be distinguished from the question of whether there has been an amendment to a party's appeal case. The admissibility of amendments represents a separate, independent issue and is subject to the discretion of the board under Article 114(2) EPC and Articles 12 and 13 RPBA."
- " In the contested decision, the opposition division held that claim 1 was novel over D1 as it did not disclose at least features 1.4 and 1.7. "
- "The board agrees with the contested decision... that D1 does not disclose ... feature 1.4."
- "The appellant [opponent] argued that, even if considered novel, claim 1 would still lack an inventive step over D1 combined with common general knowledge."
- " The appellant submitted that according to established case law and, in particular, to decision T 131/01, an inventive step attack is admissible on appeal even if only a novelty objection was raised during opposition proceedings, because the inventive step is not considered a fresh ground for opposition."
- I think T 131/01 shows that the case law based on G 10/91 is a hodgepodge of rules. G 10/91 did not identify what a 'ground of opposition' is, leaving that to G 7/95 to resolve. G 7/95 decided that novelty and inventive step are different grounds (despite the structure of Article 100 EPC). T 0131/01 created an 'exception' in a case that was not even about a fresh ground of appeal (the OD had held the inventive step attack inadmissible; the Board reversed that decision, which is nowadays seen as outside the scope of G10/91).
- If G 10/91 is about bright-line rules, then there should be no such complexity. If G 10/91 is about equitable considerations, then Article 12(4) and (6) RPBA appear to be, de lege ferenda, the way forward.
- The Board applies Art. 12(6) RPBA and does not admit the attack.
- "Under Article 12(6) RPBA, second sentence, the board shall not admit requests, facts, objections or evidence which should have been submitted, or which were no longer maintained, in the proceedings leading to the decision under appeal, unless the circumstances of the appeal case justify their admittance."
- In the present case, the patent proprietor's and the opposition division's position that D1 did not anticipate claim 1 was known to the opponent before the opposition oral proceedings (see e.g. annex to the summons to oral proceedings in opposition, point 2.2.1). Hence, the board takes the view that any inventive step attack based on D1 could and should have been filed at the latest during those oral proceedings. Moreover, the board cannot identify any circumstances which would justify the admission of such attack on appeal, nor did the appellant provide arguments in this respect."
- "Accordingly, the board decides not to admit the inventive step attack based on D1 into the appeal proceedings, Articles 12(4) and 12(6) RPBA."
