Résumé : The year 2023 will most likely be remembered in the future history of the European patent system, similarly to 1978, that marked the creation of the European Patent and the Patent Cooperation Treaty, or similarly to 1883 with the Paris Convention. Called for long the Community Patent, it has been renamed “Unitary patent” (UP), or patent with a unitary effect. Its raison d’être is to cope with the many weaknesses (see van Pottelsberghe, 2009) of the European Patent (EP) system, which reduced the effectiveness of the European patent policy in stimulating innovation.
