Catchword
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).

ORDER

For these reasons it is decided:

1. The decision under appeal is set aside.

2. The case is remitted to the first instance with the order to maintain the patent on the basis of Claims 1 to 4 of the main request filed with the submission dated 22 July 1998 and after any necessary consequential amendment of the description.
