I. The appeal lies from the decision of the opposition division posted on 4 October 2017 revoking European patent No. 0 998 522, which is based on European patent application 99 922 271.4 filed on 21 May 1999.
II. By communication of the Board of 9 February 2021, the parties' attention was drawn to the fact that as more than 20 years had passed since the filing date of the application underlying the patent in suit, the patent had to have lapsed in all contracting states (Article 63(1) EPC). It was further indicated that the present proceedings could therefore only be continued at the request of the opponent (Rule 84(1) EPC). However, if - as in the present case - the patent proprietor was the appellant, it would be inappropriate to allow the opponents (respondents) to decide whether the appeal proceedings shall be continued. For this reason, Rule 84(1) EPC had to be applied mutatis mutandis, so that it was the patent proprietor who could request that the appeal proceedings be continued (see decision T 708/01 of 17 March 2005, point 1 of the Reasons). Finally, it was stressed that such a request had to be filed within two months from notification of this communication (Rule 84(1) EPC).
III. The appellant (patent proprietor) did not reply within the time limit of two months.
IV. Additional submissions were also not made past that time limit. Upon inquiry by the Registrar, the appellant informed the Board with an email dated 27 April 2021 that they had duly received the Board's communication on 12 February 2021.
V. The oral proceedings scheduled on 2 June 2021 were subsequently cancelled.
1. The fact indicated in the Board's communication (see above section II) that the patent has lapsed in all contracting states (Article 63(1) EPC) was not contested.
2. If a European patent has lapsed in all designated contracting states, opposition proceedings may be continued at the request of the opponent (Rule 84(1) EPC). According to Rule 100(1) EPC, this also applies in appeal proceedings following opposition proceedings. However, if, as in the present case, the patent proprietor is the appellant, it would be inappropriate to allow the opponents (respondents) to decide whether the appeal proceedings shall be continued. For this reason, Rule 84(1) EPC has to be applied mutatis mutandis in such opposition appeal proceedings so that it is the patent proprietor who can request that the appeal proceedings be continued (see decision T 708/01 of 17 March 2005, point 1 of the Reasons; see also Case Law of the Boards of Appeal of the EPO, 9th edition, 2019, III.Q.1.2.2).
3. Users of the European patent system have the responsibility to take all necessary steps to avoid a loss of rights (G 2/97, OJ EPO 1999, 123, point 4.2 of the Reasons; R 4/09 of 30 April 2010, point 2.3.2 of the Reasons). By not replying to the Board's communication dated 9 February 2021 within the set time period or within the period under Rule 133(1) EPC, which was confirmed to have been duly received, the appellant failed to satisfy the stipulations of Rule 84(1) EPC with respect to the continuation of appeal proceedings. This is interpreted as meaning that the appellant did not wish to request continuation.
4. Under these circumstances, the Board sees no reason to continue the appeal proceedings of its own motion.
Therefore, the appeal proceedings are terminated without a decision on the merits of the case (Case Law, supra, III.Q.1.2).
For these reasons it is decided that:
The appeal proceedings are terminated.
