We recently reported on the opinion of the advocate general (AG) in the case CJEU (C-121/17) concerning supplementary protection certificates (SPC) and the question of when a product, which is not explicitly mentioned in the basic patent, is protected by the basic patent, according to Article 3 (a) of Regulation (EC) No 496/2009. While it has been clarified that infringement rules cannot be applied, it is still not clear which test should be used for assessing the requirement of Article 3(a). Recently, the CJEU issued a judgment on this case which interestingly differs on this point from the opinion of the AG.
