What can I do if miss the one-month period for filing a request for unitary effect?

If, in spite of taking all due care required by the circumstances, you do not meet the period for filing a request for unitary effect – that is, one month after publication of the mention of the grant of the European patent in the European Patent Bulletin (see Rule 6(1) of the Rules relating to Unitary Patent Protection (UPR)) – you can request re-establishment of rights in respect of this one‑month period (see Rule 22(1) UPR). However, your request for re-establishment must be filed within two months of expiry of the one-month period (see Rule 22(2) UPR), and you must also file the request for unitary effect within the same two-month period (Rule 22(3) UPR). You must also pay the prescribed fee.

For further details, please see the Unitary Patent Guide.
