Friday, October 14, 2016 T 497/11: Revert an amendment after 9 years

In this opposition appeal admissibility is initially an important subject of the discussion. About one month before the oral proceedings (2016) the Appellants filed amended claims which would, according to the Board, "effectively revert to the method claims they had filed in 2007". The amendment comprises the deletion of "by using a computer".
When reading also the inventive step discussion of one of the requests, it seems that the Appellants would like to delete this features from the claims to enforce the choice of the closest prior art into another direction. The selected closest prior art was generic prior art in the field of air traffic control: "A system including a processor, memory, display and input device, for an aviation system, the system further comprising means (e.g. radio) for communicating to said aircraft."
If this amendment is accepted, the board had to start a discussion of the technicality of the claims. One of the arguments of the Appellants was that the recently filed claims were filed because the representation of the Appellants changed. Is that argument enough to get the amendments into the procedure?

This decision is also interesting because a number of features of auxiliary requests are considered to be a mere automation of mental acts, for example, performed by a flight controller. Thus, although the claims are technical with the feature of "by using a computer", most features do not contribute to the inventiveness of the claims because they are not technical.
