The President of the EPO may decide ex officio under Rule 3 UPR to take the precaution of staying proceedings for the registration of unitary effect in the Register for unitary patent protection UP Register in specific situations. If proceedings are stayed, the EPO will inform the parties accordingly. It will also withdraw any communications setting them time limits for reacting and refrain from dispatching any other such communications until the registration proceedings have been resumed (e.g. Notice from the European Patent Office dated 10 July 2024 concerning the staying of proceedings for the registration of unitary effect as a precautionary measure due to the EU's 14th package of sanctions against Russia (OJ EPO 2024, A70)).
The President of the EPO may decide at any point in time that registration proceedings which have been stayed are to be resumed (e.g. Notice from the European Patent Office dated 13 November 2024 concerning the implementation of the 14th package of EU sanctions against Russia in procedures related to the Unitary Patent and the amendment to the associated amendment to the Rules relating to Unitary Patent Protection (OJ EPO 2024, A97); see 2.1).
