Any new facts or evidence should be communicated to the EPO without delay!

(Rule 57a EPC)  The patent proprietor should make any desirable amendments in opposition proceedings as soon as possible (e.g., by way of auxiliary request).

15. by Dr. Johann Pitz © 2004 VOSSIUS & PARTNER AIPPI Hungary, June 2 – 4, 2004, Kecskemét AIPPI Hungary, June 2 – 4, 2004, Kecskemét 15 Intervention of an Assumed Infringer  Any third party against which national proceedings for infringement of the European patent have been instituted may intervene in the pending opposition procedure (including appeal proceedings) within three months of the date on which the infringement proceedings were instituted.  The assumed infringer has to fulfil the same formal and substantive requirements like a regular opponent.  Intervention may be based on any ground for opposition under Art. 100 EPC (including fresh grounds for opposition).
