7. The requirement of sufficiency of disclosure in the biotechnology field

Catchword: 

In accordance with the jurisprudence exemplified by T 609/02 (see section 9), the suitability of the claimed composition for the defined therapeutic use needs to be disclosed in the patent, "unless this is already known". This jurisprudence confirms in the Boards view that the disclosed utility of the claimed composition may also derive its credibility from the prior art, even if this prior art does not represent common general knowledge (see point 3.3).

Catchword: 

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.

Headnote: 

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.
