Exergue
A fatal defect of the choice, as a starting point for the application of the problem/solution method, of a disclosure in the state of the art from which no relevant technical problem can be formulated without inappropriate hindsight is that, without such hindsight, any attempt to establish a logical chain of considerations which could lead to the claimed invention inevitably gets stuck at the start, for want of a relevant identifiable goal or object. If the relevant problem is not derivable, the measures for its solution are a fortiori not derivable. In other words, the invention is not obvious in the light of such art (cf. Reasons, point 4.4.5).
