T 1280/14 - No switching between lines of defense
Can the Board exercise its discretion under Art. 13 RPBA not to admit auxiliary requests in the proceedings even if these have already been filed in direct response to the Opponent/Appellant's grounds of appeal and correspond to those submitted during first instance proceedings?
In the present case, the Opposition Division had rejected the opposition against the patent. In the ensuing appeal, the Opponent-Appellant already requested in his grounds that none of the (39) auxiliary requests filed during opposition proceedings be admitted, as these were "excessive, filed in unspecified order, and/or late filed".
In his response to the grounds, the Proprietor-Respondent filed 15 auxiliary requests based on a selection from the requests filed during opposition proceedings. The Proprietor stated that these auxiliary requests were properly numbered, therefore having a clearly specified order. From the arguments in support of the requests it could be deduced that these requests were classifiable as forming six diverging lines of defense, auxiliary requests 1, 2 and 4 thereof forming the first line of defense.
In the summons for oral proceedings, the Board pointed out (referring to T 1903/13) that the Proprietor should be prepared to comment on how the other diverging lines of defense would represent the alleged invention. The Proprietor did not provide any further comments.
Accordingly, the Opponent/Appellant and the Board had to assume prior to the oral proceedings that the Respondent intended, after the main request, to first prepare the patent in suit in accordance with the first line of defense, with auxiliary requests 1, 2 and 4 to defend. However, it was not until the oral hearing (in which the Main Request had fallen as lacking novelty over prior art document D9 filed with the Opponent-Appellant's grounds) that the Proprietor made it clear that he now intended to only pursue his third and sixth lines of defense - corresponding to auxiliary requests 8 and 15, respectively, and renumbered as auxiliary requests 1 and 2.
This unannounced change of strategy did not fare well with the Board, who found that both the Opponent and Board had unnecessarily prepared for auxiliary requests which turned out not to be relevant in the further proceedings; thus, the Respondent had not complied with the procedural economics offered. According to the Board, contrary to the Respondent's submission, his actions did not constitute a mere renumbering of the requests, since new auxiliary requests 1 and 2 (formerly auxiliary requests 8 and 15) corresponded to lines of defense diverging from the former auxiliary requests 1, 2 and 4. Thus, what was now claimed as an invention had fundamentally shifted. Hereby, the multiplicity of interlocked features rendered the changes in subject-matter of the auxiliary requests very complex.
As a result, remaining auxiliary requests 1 and 2 were not admitted in the proceedings and the patent was revoked.
