EPO sets start of transitional measures to 1 January 2023
Aligning with the recently published implementation roadmap published by the Unified Patent Court (UPC), the EPO has decided to adjust the starting date of its transitional measures to 1 January 2023.
As of that date, patent applicants may file early requests for unitary effect and requests for a delay in issuing the decision to grant a European patent. The measures are applicable until the entry into operation of the Unitary Patent Protection system which is expected to be on 1 April 2023.
The two measures were introduced to support an early uptake of the Unitary Patent by the users.
For detailed information as to the requirements for these two measures, including some examples, please go to the dedicated webpage of the EPO.
Please note that in the revised version of the texts published by the EPO, no other change than the adjustment of the starting date of the transitional measures has been made.
