While the WTO agreements came into force on 1 January 1995, the TRIPS agreement granted WTO members certain transitional periods before they were required to implement all their provisions. Members of developed countries were given one year to ensure that their laws and practices complied with the TRIPS Agreement. Members of developing countries and, under certain conditions, the transitional economy enjoyed a five-year period until the year 2000. The least developed countries were first 11 years old, until 2006 – now they are generally extended until July 1, 2021. As in the General Agreement on Tariffs and Trade (GATT) and the General Agreement on Trade in Services (GATS), the starting point of the ON-TRIPS agreement is the basic principle. As in the other two agreements, non-discrimination plays a major role: national treatment (which does not treat foreigners less favourably than its own nationals) and the MFN (non-discriminatory among nationals of trading partners). The issue is also a key principle in other IP agreements outside the WTO. The TRIPS agreement, which came into force on 1 January 1995, is the most comprehensive multilateral agreement on intellectual property to date. The areas of intellectual property it covers are copyright and neighbouring rights (rights of performers, phonogram producers and broadcasters); Brands, including service brands; Geographical indications, including appellations of origin; Industrial designs; patents, including protection of new plant varieties; Designs for the layout of integrated circuits; and undisclosed information, including trade secrets and test data.
An agreement reached in 2003 relaxed domestic market requirements and allows developing countries to export to other countries with a public health problem as long as exported drugs are not part of a trade or industrial policy.  Drugs exported under such regulations may be packaged or coloured differently to prevent them from affecting the markets of industrialized countries. The Agreement on Trade-Related Intellectual Property Rights (TRIPS) is an agreement of international law between all World Trade Organization (WTO) member states. It sets minimum standards for the regulation of different forms of intellectual property by national governments, as is the case for nationals of other WTO member states.  The TRIPS agreement was negotiated at the end of the Uruguay Round of the General Agreement on Tariffs and Trade (GATT) between 1989 and 1990 and is managed by the WTO. The main changes introduced in India`s patent law, which were necessary to meet India`s obligations to international agreements and treaties. The new Patents Amendment Act 2005 created a strong patent system in India.
