Article 71b

The jurisdiction of a common court shall be determined as follows:
(1) a common court shall have jurisdiction where, under this Regulation, the courts of a Member State party to the instrument establishing the common court would have jurisdiction in a matter governed by that instrument;
(2) where the defendant is not domiciled in a Member State, and this Regulation does not otherwise confer jurisdiction over him, Chapter II shall apply as appropriate regardless of the defendant’s domicile.
Application may be made to a common court for provisional, including protective, measures even if the courts of a third State have jurisdiction as to the substance of the matter;
(3) where a common court has jurisdiction over a defendant under point 2 in a dispute relating to an infringement of a European patent giving rise to damage within the Union, that court may also exercise jurisdiction in relation to damage arising outside the Union from such an infringement.
Such jurisdiction may only be established if property belonging to the defendant is located in any Member State party to the instrument establishing the common court and the dispute has a sufficient connection with any such Member State.
