- It cannot be taken from the reasoning of the Enlarged Board in G 1/23 that where a modification of a non-reproducible but commercially available product as such is necessary, then the non-reproducible product does not form the closest prior art. What needs to be modified is part of the inventive thinking of the skilled person in order to solve the problem addressed, but not a consideration concerning the selection of that starting point.
