5.2. Application of the case law established by the Enlarged Board
In T 1431/12, the reason given for Mr W.'s making submissions was that he was a trainee patent attorney familiar with the case. It was therefore unlikely that his submissions (unlike, for example, an expert's) would go beyond those of a patent attorney specialising in the subject-matter and so would not mean that the appellant would have to commission an expert to counter them. Given those circumstances, the board exercised its discretion to permit Mr W. to provide any technical information necessary to supplement the submissions made by the professional representative supervising him.
For a classic application of the requirements set out in G 4/95 to a party's contention that, since the accompanying person was preparing for the European qualifying examination, he ought to be given a training opportunity, see T 378/08, in which permission for the person to make oral submissions was refused.
