T 777/08: When is a Polymorph Inventive?
In view of the principles outlined in the recent decision T 777/08 it has to be expected that in the future the inventiveness of a novel polymorph form of a pharmaceutically active compound will be acknowledged only if the novel polymorph form is associated with an unexpected pharmaceutical activity, while improved physical and/or physicochemical properties would not be sufficient. Also, an inventive step might be acknowledged if an inventive activity is required to actually manufacture the polymorph.
