1. Where a distinguishing feature does not credibly contribute to the solution of a technical problem, it normally constitutes an "arbitrary modification" of the prior art which cannot support an inventive step. This principle applies independently of whether the feature is technical or non-technical in nature (see Reasons 3.4).
2. There is no "customary practice" in appeal proceedings that grants a party the right to have written submissions filed one month prior to oral proceedings automatically admitted into the appeal proceedings. Consequently, reliance on such an alleged "practice" cannot justify a derogation from the explicit provisions of Article 13(2) RPBA (see Reasons 4 and 5).
