As reported by the EPO in a Press Communiqué of 25 September 2025, the Enlarged Board of Appeal has rendered decision G 2/24 (“Skin cleanser”) that relates to the procedural status of an intervener in opposition appeal proceedings.

The Enlarged Board confirmed its previous decision G 3/04 and concluded that, after withdrawal of all appeals, appeal proceedings may not be continued with a third party who intervened only during the appeal proceedings (see the EPO’s Press Communiqué of 25 September 2025).

In proceedings before the EPO, the question of whether appeal proceedings may be continued, after withdrawal of the sole appeal, with a party who intervened at the appeal stage has been settled for a long time. The Enlarged Board of Appeals (EBA) held in decision G 3/04: “After withdrawal of the sole appeal, the proceedings may not be continued with a third party who intervened during the appeal proceedings.”

In T 1286/23, the Board brings this question before the Enlarged Board of Appeals again. As stated in r. 3.7 of the decision, “[the] referring Board is … not in agreement that Article 105 EPC in combination with Article 107 EPC must be read in the sense that also a third party intervening only at the appeal stage can never become more than a non-appealing opponent.” The referring Board provides detailed reasons for this position in r. 3.7 et seq. of the decision.

Thus, the procedural question pertaining to a party who intervened at the appeal stage is going to be revisited.
