Sommaire

The following questions concerning important points of law are referred to the Enlarged Board of Appeal for decision:

1. When amended claims involving a change of category (here: from a "compound" claim to "use of that compound in a composition for specified purpose") are proposed in opposition proceedings, what considerations should be taken into account when deciding on the admissibility of such amendments having regard to Article 123(3) EPC? In particular, how far should the national laws of Contracting States relating to infringement be considered?

2. Can a patent with claims directed to a "compound" and to a "composition including such compound" be amended during opposition proceedings so that the claims are directed to the "use of that compound in a composition" for a particular purpose?

3. Is a claim to the use of a composition for a particular non-medical purpose novel for the purpose of Article 54 EPC, having regard to a prior publication which discloses the use of that compound for a non-medical purpose, so that the only novel feature in the claim is the purpose for which the compound is used?

ORDER

For these reasons, it is decided that:

The following questions concerning important points of law shall be referred to the Enlarged Board of Appeal for decision: (i) When amended claims involving a change of category (here: from a "compound" claim to "use of that compound in a composition for specified purpose") are proposed in opposition proceedings, what considerations should be taken into account when deciding on the admissibility of such amendments having regard to Article 123(3) EPC? In particular, how far should the national laws of Contracting States relating to infringement be considered? (ii) Can a patent with claims directed to a "compound" and to a "composition including such compound" be amended during opposition proceedings so that the claims are directed to the "use of that compound in a composition" for a particular purpose? (iii) Is a claim to the use of a compound for a particular non-medical purpose novel for the purpose of Article 54 EPC, having regard to a prior publication which discloses the use of that compound for a different non-medical purpose, so that the only novel feature in the claim is the purpose for which the compound is used?
