3.3 Notices of opposition filed by fax 

Notice of opposition may also be filed by fax (see the decision of the President of the EPO dated 20 February 2019, OJ EPO 2019, A18). At the invitation of the EPO, written confirmation reproducing the contents of the fax and complying with the requirements of the Implementing Regulations – in particular properly signed – must be supplied. If the opponent fails to comply with this invitation in due time, the fax is deemed not to have been received (see A‑VIII, 2.5). The opposition fee must in any case be paid within the opposition period.
