| Headnote: | 1. A figure which serves only to give a schematic explanation of the principle of the subject-matter of the patent and not to represent it in every detail does not allow the sure conclusion that the disclosed teaching purposively excludes a feature not represented. Such a "negative" feature (here: "with no internal fittings") may not subsequently be incorporated into the claim. 2. A disclaimer can be used to make an inventive teaching which overlaps with the state of the art novel but it cannot make an obvious teaching inventive. |
