A UP can be obtained based on any European patent that grants on or after the date on which the UPC opens for business (“the unitary patent system start date”), which will be on 1 June 2023.

For European patent applications which are currently pending and where the text for grant has not yet been approved, it should be possible to delay grant for long enough to keep open the possibility of obtaining a UP post-grant.

Prior to the UPC opening, from 1 January 2023 the EPO has allowed applicants to request a delay to grant of a European patent application as long as the request is filed before the text for grant is approved. Grant will then be delayed until on or shortly after the unitary patent system start date.

Other options for delaying grant include requesting amendment of the text for grant and issue of a new Communication under 71(3) EPC, and/or making use of further processing to delay response to the Communication under 71(3) EPC.

A valid request to delay grant can only be filed after the communication under Rule 71(3) EPC has issued and before approval of the text, although the EPO has indicated that a request for delay filed on the same day as the approval of the text intended for grant will be considered to have been validly filed.
