Headnote

I. In the case of an active agent which is known as such to be water-soluble, it is clear to a person skilled in the art that describing and claiming the active agent as a solution does not add to or change the definition of that active agent.

II. Analogously, in a claim directed to a preparation of a known structurally defined active agent with at least one auxiliary substance, in which the feature "with an auxiliary substance or auxiliary substances" means that something is added to the active agent, the admixture of an unspecified auxiliary substance cannot, in view of the unlimited number of substances which may enter into consideration, be deemed a substantive and distinctive addition to the active agent, unless this feature, which is necessary if novelty is to be recognised, is specified in such a way that a person skilled in the art can recognise what it is that should be added to the active agent (see reason No. 4).

Keywords
Main and auxiliary requests - formally allowable - industrial applicability of the use of a substance to make a physical form under Article 57 EPC (yes)
Main request - novelty (no) - in the case of a non-defined [auxiliary] substance of unspecified effect, lack of functionality leads to lack of delimitation
Auxiliary request - inventive step (no) - obvious alternative physical form of the known substance
