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. In addition to the basic intellectual property standards set out in the TRIPS agreement, many nations have committed to bilateral agreements to adopt a higher level of protection. This collection of standards, known as TRIPS or TRIPS-Plus, can take many forms.
 The general objectives of these agreements are: the conditions of the plus members, which impose standards beyond the trips, have also been examined.  These free trade agreements contain conditions that limit the ability of governments to introduce competition for generic drug manufacturers. In particular, the United States has been criticized for promoting protection far beyond the standards prescribed by the TRIPS. The U.S. free trade agreements with Australia, Morocco and Bahrain have expanded patentability by making patents available for new uses of known products.  The TRIPS agreement authorizes the granting of compulsory licences at the discretion of a country. The terms of trips plus in the U.S. Free Trade Agreement with Australia, Jordan, Singapore and Vietnam have limited the application of mandatory licences to emergencies, remedies for cartels and abuse of dominance, and cases of non-commercial public use.  Unlike other IP agreements, TRIPS have an effective enforcement mechanism. States can be disciplined by the WTO dispute settlement mechanism.
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.
