In this training module, you will find training material, informing you on various relevant aspects relating to oral proceedings via videoconference in both examination and opposition proceedings.

Since April 2020, all oral proceedings before examining divisions are held by videoconference and since May 2020, the EPO has been conducting a pilot project for oral proceedings by videoconference before opposition divisions (see the relevant decision and notice  and the decision concerning the extension and modification of the pilot project; see also continually updated information and the FAQ)Under the terms of the project, oral proceedings before opposition divisions are held by videoconference via Zoom. The oral proceedings held by videoconference apply for multiparty hearings including with/without interpretation and with/without taking evidence.

This training module, produced by the EPO in co-operation with the epi, starts with an introduction to the legal background and technical requirements for such online proceedings, then provides information on how to best advocate a case online and finally provides further information related to opposition via videoconference, including a recording of mock oral proceedings held by videoconference. The mock proceedings were conducted by a real EPO opposition division with experienced European patent attorneys including interpretation in the EPO official languages. 

In the recordings, you will see how formalities are completed in oral proceedings held by videoconference via Zoom. For instance, you will see how:

  • a videoconference is started with distributed participation
  • the identity of the persons involved is checked
  • participation by members of the public is facilitated
  • the proceedings are opened
  • submissions by email may be performed
  • the proceedings are interrupted and resumed, e.g. for deliberation in non-public breakout rooms by the division
  • decisions are announced and proceedings are closed.
