Schlagwörter
Admissibility of appeal (yes)
Inventive step (yes) - different starting point in prior art - formulation of technical problem - solution non-obvious
Orientierungssatz
The technical problem arising from a "closest state of the art" disclosure which is irrelevant to the claimed subject-matter in the sense that it does not mention a problem that is at least related to that derivable from the patent specification has a form such that its solution can practically never be obvious, because any attempt by the skilled person to establish a chain of considerations leading in an obvious way to the claimed subject-matter gets stuck at the start. It follows that the respective claimed subject-matter is non-obvious in the light of such art.

ORDER

For these reasons it is decided that:

1. The appeal is admissible.

2. The appeal is dismissed.
