A Member State may, on a transitional basis only, grant protection to a name under this Regulation at national level, with effect from the date on which an application is lodged with the Commission.
Such national protection shall cease on the date on which either a decision on registration under this Regulation is taken or the application is withdrawn.
Where a name is not registered under this Regulation, the consequences of such national protection shall be the sole responsibility of the Member State concerned.
The measures taken by Member States under the first paragraph shall produce effects at national level only, and they shall have no effect on intra-Union or international trade.
