Patents have been criticized in the developing world, as they are thought to reduce access to existing medicines. Reconciling patents and universal access to medicine would require an efficient international policy of price discrimination. Moreover, under the TRIPS agreement of the World Trade Organization, countries must allow pharmaceutical products to be patented. In 2001, the WTO adopted the Doha Declaration, which indicates that the TRIPS agreement should be read with the goals of public health in mind, and allows some methods for circumventing pharmaceutical monopolies: via compulsory licensing or parallel imports, even before patent expiration.
In March 2001, 40 multi-national pharmaceutical companies brought litigation against South Africa for its Medicines Act, which allowed the generic production of antiretroviral drugs (ARVs) for treating HIV, despite the fact that these drugs were on-patent. HIV was and is an epidemic in South Africa, and ARVs at the time cost between US$10,000 and US$15,000 per patient per year. This was unaffordable for most South African citizens, and so the South African government committed to providing ARVs at prices closer to what people could afford. To do so, they would need to ignore the patents on drugs and produce generics within the country (using a compulsory license), or import them from abroad. After international protest in favour of public health rights (including the collection of 250,000 signatures by Médecins Sans Frontières), the governments of several developed countries (including The Netherlands, Germany, France, and later the US) backed the South African government, and the case was dropped in April of that year.
In 2016, GlaxoSmithKline (the world's sixth largest pharmaceutical company) announced that it would be dropping its patents in poor countries so as to allow independent companies to make and sell versions of its drugs in those areas, thereby widening the public access to them. GlaxoSmithKline published a list of 50 countries they would no longer hold patents in, affecting one billion people worldwide.
