4.4.3 Limitations to the reformulation of the technical problem

Catchword:

Since the problem and solution approach defines the problem based on the effect of the differences from the closest prior art, and the effect is derived primarily from the disclosure of the invention, the effect documented in the present documents alone is taken as the basis for the problem formulation. The Board concluded that any further, undocumented effects would be speculative and should not be additionally included in the problem formulation (reasons 5.3.2)
