The “Unitary Patent Guide” aims to provide companies, inventors and their representatives with an outline of the procedure involved in obtaining a Unitary Patent from the European Patent Office (EPO) once it has granted a European patent on the basis of the provisions laid down in the European Patent Convention (EPC). The guide also deals with the accessory procedures relating to Unitary Patents, such as those to be followed under the compensation scheme for translation costs or when registering a statement on licences of right, and gives an overview of the rules on how to pay renewal fees for Unitary Patents.
