(1) If several persons are party to the proceedings on the appeal on points of law, the Federal Court of Justice may determine that the costs which were necessary to appropriately deal with the matter are to be reimbursed in full or in part by one of the parties if this is equitable. If the appeal on points of law is refused or rejected as inadmissible, the costs caused by the appeal on points of law are to be imposed on the appellant. If a party has caused costs through gross negligence, they are to be imposed on that party.
(2) Costs may be imposed on the President of the German Patent and Trade Mark Office only if he or she has filed the appeal on points of law or brought motions in the proceedings.
(3) In all other cases, the provisions of the Code of Civil Procedure concerning the procedure for the assessment of costs and compulsory enforcement based on orders assessing the costs apply accordingly.
