Catchword
If a claim is unduly broadened with respect to the scope of the examples used to illustrate a technical effect, particularly when this broadening concerns the feature/s allegedly providing that effect, the burden of proof might shift back to the proprietor to prove that the effect observed in the examples would also be obtained throughout the entire scope of the claims. If no evidence is provided in this respect, a conclusion may have to be drawn on the basis of plausibility arguments (reasons 2.2.5-2.2.7).
