Résumé de EPC2000 Art 076(1) pour la décision T1054/22 du 14.06.2024

In T 1054/22 the examining division had concluded that claim 1 of the main request did not fulfil requirements of Art. 123(2) or 76(1) EPC, among other things, and it refused the patent application. In its submissions on appeal, the applicant had argued that applying the criteria of G 1/93 (point 16 of the Reasons), the amendments did not result in an unwarranted advantage. Amended claim 1 of the main request was based on the earlier application as filed. This applied in particular to the amendments concerning the omega-6 to omega-3 ratio of 4:1 or greater and the concentration of omega-6 fatty acids (4-75% by weight of total lipids) and omega-3 fatty acids (0.1-30% by weight of total lipids). The board dismissed the appeal. It explained that determining whether an amendment complied with the requirements of Art. 123(2) and 76(1) EPC was assessed using the "gold standard". This term was coined in G 2/10, in which the jurisprudence developed by the Enlarged Board in opinion G 3/89 and decision G 11/91 was confirmed. The board explained that G 1/93 primarily concerned a case in which a granted claim could not be maintained unamended in opposition proceedings because the claim was found to contravene Art. 123(2) EPC. The examining division had allowed an amendment that should not have been allowed. As explained in G 2/10 (point 4.3 of the Reasons, last paragraph), G 1/93 was not intended to modify the "gold standard". According to G 1/93, the purpose of Art. 123(2) EPC (and Art. 76(1) EPC) was to prevent an applicant from gaining an unwarranted advantage by obtaining patent protection for something it had not properly disclosed on the date of filing of the application. An added feature limiting the scope of the claim may still contravene Art. 123(2) EPC. An example of this, explicitly mentioned in G 1/93, is a limiting feature that creates an inventive selection not disclosed in the application as filed or otherwise derivable therefrom. In the case in hand, value ranges had been added to claim 1 of the main request, in features a), (i) and (ii). The question was whether the skilled person would have derived these amendments directly and unambiguously, using common general knowledge, from the entirety of the earlier application as filed. What had to be examined was not only whether there was a basis for each of the features added by the amendments but also whether the skilled person would have derived the combination of features a), (i) and (ii), and that combination of features alone, from the earlier application as filed. The board concluded that no basis could be found in the earlier application as filed for the combination of the concentration of omega-6 fatty acids of 4-75% by weight of total lipids and omega-3 fatty acids of 0.1-30% by weight of total lipids (feature (i) of claim 1 of the main request). As to the ratio (feature a) of claim 1 of the main request), there was no basis in the earlier application as filed for an open-ended ratio of omega-6 to omega-3 fatty acids of 4:1 or greater. Thus, claim 1 of the main request contravened Art. 76(1) EPC.
