Zusammenfassung von Article 084 EPC für die Entscheidung T2116/22 vom 18.12.2024

In T 2116/22 the interpretation of the terms "coating" and "coated" in claim 1 of the main request was relevant to assess novelty. The appellants-patent proprietors argued that these terms had to be interpreted taking into account the whole patent. The skilled person would have understood the coating step and the thrombin-coated gelatin granules defined in the claims as being limited respectively to a process as specified in paragraph [0014] of the patent and to thrombin coated gelatin granules prepared thereby. The board observed that the wording of the claim did not restrict the coating step to the specific coating conditions mentioned in paragraph [0014] of the patent. While the limitation of the final product being a "dry and stable" hemostatic composition may imply some limitations on the process steps, these encompassed any process features resulting in a dry and stable product such as indeed the ones described in paragraph [0014] of the patent but also any other process features providing a dry and stable product. The board further noted that the term "coating" or "coated" had a clear meaning in the field of pharmaceutical preparations and corresponded to the application of a material to the surface of a pharmaceutical solid product. This was usually done by applying the coating material as a solution or suspension to the pharmaceutical solid product and evaporating the vehicle. Paragraph [0014] of the patent did not provide a different definition of the term "coating" or "coated" than the one commonly accepted in the art. The description provided first a description of the process in broad terms as in claim 1 before describing more specific embodiments and preferred features, such as in paragraph [0014]. Whether read alone or in the light of the entire description, the meaning of the coating step or the coated product remained the same. In the context of the discussion regarding the interpretation of the terms "coating" and "coated", the appellants-patent proprietors had requested that the board stay the proceedings in view of the pending referral G 1/24. The board stated that the provisions in the EPC concerning a stay of proceedings following a referral to the Enlarged Board only concerned the referring board (Art. 112(3) EPC). There was, however, no legal basis in the EPC nor in the Rules of Procedure of the Boards of Appeal requiring that any other board stay its proceedings to await the outcome of the proceedings before the Enlarged Board. The decision whether or not to stay the proceedings in such cases was thus a discretionary one. According to the board, the strict approach taken in T 166/84, namely to stay the proceedings whenever the outcome of the proceedings depended entirely on the outcome of the referral, had been applied by some boards (e.g. T 426/00, T 1875/07 and T 1044/07). However, it had also been put into question for lack of a legal basis, and considered not to apply to proceedings before the Boards of Appeal (e.g. T 1473/13 and T 1870/16). The board was of the view that a strict application of the approach taken in T 166/84 would in effect deny a board its discretion as to whether to stay the proceedings. The discretion was however the inevitable consequence of the fact that there was no legal basis for requiring a board that had not referred the relevant questions to the Enlarged Board to stay the proceedings. Moreover, the outcome of the referral G 1/24 was not decisive for the decision in the case at hand. The board decided not to stay the proceedings in view of the pending referral G 1/24 and concluded that claim 1 of the main request was not novel. During the course of the oral proceedings, the appellants-patent proprietors filed an objection under R. 106 EPC. The board reiterated that the decision to stay the proceedings remained a discretionary one. The appellants-patent proprietors had had ample opportunities to present their comments on the issue of a stay of the proceedings, so that no violation of their right to be heard occurred (Art. 113(1) EPC). Moreover, the outcome of the referral G 1/24 was not decisive for the decision in the present case, including on novelty of the main request. Therefore, the board dismissed the objection under R. 106 EPC.
