III. Filing the request for unitary effect
67If the period for filing a request for unitary effect – that is, no later than one month after publication of the mention of the grant of the European patent in the European Patent Bulletin (see Rule 6(1) UPR) – has not been observed, you can request re-establishment of rights in respect of this one-month period (see Rule 22(1) UPR). Your request for re-establishment must however 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 and pay the prescribed fee within the same two-month period (Rule 22(3) UPR, Article 2(2) RFeesUPP).
