Reflections on Article 30 of the Trips agreement and lessons from WTO dispute settlement body practice

Article 30of the Trips agreement is relating to the exceptions and limitation of patent holders. Protection of the holders is the predominant approach in the Trips agreement meanwhile the main goal of the Intellectual property rights is to balance the private right of holders and the interest of societies. one of the main mechanism that provided in the Trips to achieve the mentioned goal is use the exceptions which provided in the Article 30but the ambiguous in this Article cause the different interpretation between Developed and developing countries. The jurisprudence of dispute settlement body of the WTO could not to remove the said ambiguous regarding the delimitation of private and public interest in the patent system and despite the dispute settlement body decision regarding the exception of the IP holder the contracting state of Trips have different interpretation.
