[Essential medicines and the TRIPS Agreement: collision between the right to health and intellectual property rights].

The strengthening of pharmaceutical patent protection globally puts strains on access to essential medicines. According to the present paper, this process has led to the collision of the intellectual property rights adopted in the World Trade Organization (WTO) Trade-Related Aspects of Intellectual Property Rights (TRIPS) Agreement and the right to health stated in the International Covenant on Economic, Social and Cultural Rights (ICESCR). Several controversies disputed in the WTO illustrate the confrontation between countries with a powerful pharmaceutical industry and the interests of developing countries. It is concluded that the TRIPS-plus rules subscribed to by developing countries in free trade agreements which give the pharmaceutical patent holder more rights than those stipulated in the original TRIPS Agreement are incompatible with the obligations to provide access to essential medicines under the right to health of the ICESCR.
