In the beginning of 2010, Merck Sharp & Dohme (hereafter “Merck”) and E.I. Du Pont de Nemours (hereafter “Du Pont”) on the one hand and Mylan on the other hand entailed in a fight concerning the launch of a generic version of Cozaar Plus®. The Supplementary Protection Certificate (SPC) of Cozaar Plus®, a combination product consisting of losartan and HCTZ, would expire on 15 February 2010, but Merck and Du Pont tried to prevent the marketing of generic versions of Cozaar Plus® by invoking the SPC for Cozaar®, the monoproduct consisting of Losartan only. In Belgium and France, this case led to very diverging judgments on the interpretation of the SPC Regulation.
