The creation of the unitary patent and the Unified Patent Court (“UPC”) heralds the beginning of a new era in patent law in Europe. The Agreement on a Unified Patent Court (“UPCA”) entered into force on 1 June 2023 when the new UPC finally began operations. The opening of the UPC also coincides with the introduction of a new “unitary patent”. From now on, innovative companies will no longer have to apply for, maintain and, in the event of a dispute, enforce patents in court individually for all European Union (“EU”) Member States in order to protect their technical inventions. The new system provides a uniform court procedure with direct effect of the decisions for all participating EU Member States.
