If the Office finds that the application for a declaration of invalidity is admissible, the Office shall examine whether the grounds for invalidity referred to in Article 25 prejudice the maintenance of the registered Community design.

In the examination of the application, which shall be conducted in accordance with the implementing regulation, the Office shall invite the parties, as often as necessary, to file observations, within a period to be fixed by the Office, on communications from the other parties or issued by itself.

The decision declaring the registered Community design invalid shall be entered in the register upon becoming final.
