Structural similarity of chemical compounds
Existence of common general knowledge regarding equivalency contested - Orientierungssatz
- To deny inventive step for novel chemical compunds because of their "structural similarity" to known chemical compounds would be justified, if the skilled person knew, be it from common general knowledge, or from some specific disclosure, that the existing structural differences of the chemical compunds concerned were so small that they would have no essential bearing on those properties which are important for solving the technical problem underlying the invention (No. 8.2)
