Key points
- The title is not a tautology.
- "The patent proprietor lodged an appeal against the interlocutory decision of the opposition division finding that European patent No. 2 737 379 as amended according to auxiliary request 1A met the requirements of the [EPC]"
- "During the oral proceedings held before the opposition division, the sole opponent withdrew its opposition against the patent. The opposition division then continued the proceedings of its own motion in accordance with Rule 84(2) EPC."
- In the contested decision, the opposition division came to the conclusion that the ground for opposition under Article 100(c) EPC prejudiced the maintenance of the patent as granted, that the subject-matter of claim 1 according to auxiliary request 1 filed with letter dated 13 November 2020 was not novel over document SP06"
- This is a rare case where interlocutory revision was possible in an opposition appeal.
- "The [operative] second auxiliary request includes a total of four independent claims: claims 1, 2, 3 and 12. Independent claims 2 and 3 are identical to claims 1 and 2 of auxiliary request 1A on the basis of which the opposition division intended to maintain the patent. "'
- "Since the patent proprietor is the sole appellant in the present case, the maintenance of the patent on the basis of claims that are identical in wording to those of auxiliary request 1A, which the opposition division had found to comply with the EPC, may in principle not be challenged. Otherwise the sole appellant would be put in a worse situation than if it had not filed an appeal. This follows from the prohibition of reformatio in peius, as established in the decision of the Enlarged Board of Appeal G 9/92 "
- "Hence, the board can in principle not examine or object to independent claims 2 and 3 of the second auxiliary request without contravening the principle of prohibition of reformatio in peius. The same applies to dependent claims 4 to 6, 8 and 9 of the second auxiliary request, at least insofar as they depend on independent claims 2 or 3."
- The Board examines the novelty of claim 1.
- "the opposition division concluded that it lacked novelty over document SP06 (Reasons 4 for the decision under appeal). In particular, it was held that the embodiment of the low pressure gradient system ("Niederdruck-Gradientensystem") as shown in Figure 4.2 on page 65 of document SP06"
- "The opposition division's view on feature F1.2 seems to be based on the false premise that for concluding lack of novelty it is sufficient that all claim features are disclosed in the same prior art document. It is well-established in the case law of the Boards of Appeal that, unless there is a clear teaching combining different passages in a document, these passages may not be combined for the examination of novelty"
- "In view of the above, the subject-matter of claim 1 of the second auxiliary request is new over document SP06 (Article 54(1) and (2) EPC)."
- "The board exercised its discretion under Article 111(1) EPC to remit the case to the opposition division for further prosecution."
- "The board finds it fitting to add here that the prohibition of reformatio in peius prevails in principle until the final settlement of the opposition case and, therefore, also in opposition proceedings subsequent to a remittal under Article 111 EPC (T 1843/09, Reasons 2.3.3). The claims setting the framework for reformatio in peius are those according to auxiliary request 1A as held allowable by the opposition division in the decision underlying this appeal".
