Article 4

1.   In the event of a dispute relating to an alleged infringement of a European patent with unitary effect, the patent proprietor shall provide at the request and the choice of an alleged infringer, a full translation of the European patent with unitary effect into an official language of either the participating Member State in which the alleged infringement took place or the Member State in which the alleged infringer is domiciled.

2.   In the event of a dispute relating to a European patent with unitary effect, the patent proprietor shall provide in the course of legal proceedings, at the request of a court competent in the participating Member States for disputes concerning European patents with unitary effect, a full translation of the patent into the language used in the proceedings of that court.

3.   The cost of the translations referred to in paragraphs 1 and 2 shall be borne by the patent proprietor.

4.   In the event of a dispute concerning a claim for damages, the court hearing the dispute shall assess and take into consideration, in particular where the alleged infringer is a SME, a natural person or a non-profit organisation, a university or a public research organisation, whether the alleged infringer acted without knowing or without reasonable grounds for knowing, that he was infringing the European patent with unitary effect before having been provided with the translation referred to in paragraph 1.
