o) Information supporting oral submissions 

In T 247/20 the appellant (patent proprietor) filed slides containing figures illustrating its interpretation of relevant processes of the patent and D1 two months before the oral proceedings. The board did not regard these figures as evidence, or a change in the appellant's appeal case, but as supporting information for the appellant's oral presentation, albeit filed in advance of the oral proceedings. The board made it clear that they were thus part of the appeal proceedings and it had no discretion not to admit them.
