Keywords: Novelty - no, no new choice
Late filed evidence - admitted
New claims filed during oral proceedings - admitted
Catchwords:

There is no basis in the EPC to refuse auxiliary requests at oral proceedings because of the circumstance that the new claims are apparently "not clearly allowable". In contrast to the situtation in examining proceedings, where Rule 86(3) EPC requires that amendments after expiration of the time limit set in the first communication of the EPO are subject to the consent of the EPO, Rule 57a EPC does not contain such a requirement. The discretion not to admit auxiliary requests should in principle be limited to exceptional cases in which the filing of the auxiliary request can be said to amount to an abuse of procedural rights (point 3 of the reasons).
