If the members of the division are in different locations, how will they all receive any documents I send by email at the same time?

At the beginning of the oral proceedings, the chair will explain how to file submissions, and the email addresses to be used by all parties will be provided (see decision of the President of the EPO dated 13 May 2020 (OJ EPO 2020, A71)).

Please note that emails from external parties to the EPO pass through filters and can take a few minutes to arrive if they include attachments.
