Following our note “The Future European Patent System: Being Prepared,” we report here on the very latest news on the implementation of the major changes to the European patent system. In recent weeks, there has been important news relating to the dismissal of Spain’s challenge in the Court of Justice of the European Union, which was the final legal hurdle to the system, and also as to the proposed level of fees in the new system — namely those for litigation in the Unified Patent Court (including the opt-out fee) and for renewing a Unitary Patent, both of which will influence how the system is used.
