Extension of electronic notification via the EPO Mailbox to appeal proceedings

With effect from 1 June 2021, the Boards of Appeal will begin to notify documents in appeal proceedings electronically via the EPO Mailbox (see Notice of the President of the Boards of Appeal dated 13 April 2021 concerning the extension of electronic notification via the EPO Mailbox to appeal proceedings, OJ EPO 2021, A37). Thus, all communications, summonses and decisions relating to appeal proceedings before the Technical Boards of Appeal and the Legal Board of Appeal will be notified electronically via the Mailbox, where the addressee has activated this service. A list of the relevant documents is available at https://www.epo.org/applying/online-services/mailbox.html
