25With regard to the purpose of the rule laid down in the first sentence of Article 23(1) of the Regulation, the Court takes the view that, having regard to what has been established in paragraphs 20 and 21 of the present judgment, the lack of effects, vis-à-vis third parties, of the legal acts referred to in Articles 17, 19 and 22 of the Regulation which have not been entered in the Register is intended to protect a person who has, or may have, rights in a Community trade mark as an object of property. It follows that the first sentence of Article 23(1) of the Regulation does not apply to a situation, such as that in the main proceedings, in which a third party, by infringing the mark, infringes the rights conferred by the Community trade mark.
