24It follows that, as from the date of accession, the principles laid down by the Court on the basis of Treaty articles relating to the free movement of goods are applicable to trade between the new Member States and the other EU Member States. The Court has consistently held that the proprietor of an industrial or commercial property right protected by the legislation of a Member State cannot rely upon that legislation to prevent the importation of a product which has been lawfully marketed in another Member State by the proprietor himself or with his consent. The Court has inferred from that principle that an inventor, or someone deriving rights from him, cannot invoke the patent which he holds in one Member State to prevent the importation of a product freely marketed by him in another Member State where the product is not patentable (judgments in Centrafarm and de Peijper, 15/74, EU:C:1974:114, paragraphs 11 and 12; Merck, 187/80, EU:C:1981:180, paragraphs 12 and 13; and Generics and Harris Pharmaceuticals, C‑191/90, EU:C:1992:407, paragraph 31).
