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 2002 Doha Declaration confirmed that the TRIPS agreement should not prevent members from taking the necessary steps to protect public health. Despite this recognition, less developed countries have argued that flexible TRIPS provisions, such as mandatory licensing, are almost impossible to obtain. The least developed countries, in particular, have made their young domestic manufacturing and technological industries proof of the infallible policy. Since the TRIPS agreement came into force, it has been criticized by developing countries, scientists and non-governmental organizations. While some of this criticism is generally opposed to the WTO, many proponents of trade liberalization also view TRIPS policy as a bad policy. The effects of the concentration of WEALTH of TRIPS (money from people in developing countries for copyright and patent holders in industrialized countries) and the imposition of artificial shortages on citizens of countries that would otherwise have had weaker intellectual property laws are common bases for such criticisms. Other critics have focused on the inability of trips trips to accelerate the flow of investment and technology to low-income countries, a benefit that WTO members achieved prior to the creation of the agreement. The World Bank`s statements indicate that TRIPS have clearly not accelerated investment in low-income countries, whereas they may have done so for middle-income countries.
 As part of TRIPS, long periods of patent validity were examined to determine the excessive slowdown in generic drug entry and competition. In particular, the illegality of preclinical testing or the presentation of samples to be authorized until a patent expires have been accused of encouraging the growth of certain multinationals and not producers in developing countries. This is likely due to the lack of legal and technical expertise needed to develop legislation to implement flexibility, which has often led developing countries to directly copy intellectual property legislation in industrialized countries or to need technical assistance from the World Intellectual Property Organization (WIPO) that encourages them to , according to critics like Cory Doctorow to introduce more powerful intellectual property monopolies. former Deputy Director General of the Swiss Intellectual Property Office (now the Intellectual Property Institute) and Legal Adviser, Department of External Economic Relations (now Secretary of State for Economic Affairs); Chief negotiators in TRIPS, dispute resolution and subsidies during the Uruguay Round.
