C. Sufficiency of disclosure
- T 424/21
1. If the deletion of dependent claims after notification of a summons to oral proceedings enhances procedural economy by clearly overcoming existing objections without giving rise to any new issues this might constitute cogent reasons justifying exceptional circumstances in the sense of Article 13(2) RPBA 2020.
2. For a first medical use of a substance or composition according to Article 54(4) EPC to be sufficiently disclosed it is not required to show the suitability for each and every disease, but it usually suffices to show that at least one medical use is credibly achieved.
- T 500/20
Reasons 3.6. In claimed inventions that do not involve a range of parameter values or compositions but are directed at a concept expressed in terms of generic structural or functional features of an apparatus or of a method, it is not enough to demonstrate insufficiency to conceive of an example that falls within the terms of the claim that does not work because it does not achieve the claimed effect fully or at all so that therefore the invention would not be sufficiently disclosed across the entire breadth of the claim.
- G 2/21
I. Evidence submitted by a patent applicant or proprietor to prove a technical effect relied upon for acknowledgement of inventive step of the claimed subject-matter may not be disregarded solely on the ground that such evidence, on which the effect rests, had not been public before the filing date of the patent in suit and was filed after that date.
II. A patent applicant or proprietor may rely upon a technical effect for inventive step if the skilled person, having the common general knowledge in mind, and based on the application as originally filed, would derive said effect as being encompassed by the technical teaching and embodied by the same originally disclosed invention.
