Court of Justice of the European Communities, C-267/95 and C-268/95
Articles 30 and 36 of the EC Treaty preclude application of national legislation which grants the holder of a patent for a pharmaceutical product the right to oppose importation by a third party of that product from another Member State in circumstances where the holder first put the product on the market in that State after its accession to the European Community but before the product could be protected by a patent in that State, unless the holder of the patent can prove that he is under a genuine, existing legal obligation to market the product in that Member State.
