First of all, as we all know, India is a country with a large number of poor people. Many people lost their lives and health because they couldn't afford such expensive medicine, which led to poverty. 1970, Indian prime minister Indira Gandhi solved this problem by amending the patent law. The revised patent law stipulates that for food and medicine, only process patents are granted, not product patents, which means that India has given up the protection of intellectual property rights of pharmaceutical compounds. This relatively loose system enables domestic enterprises to obtain a large number of generic drug production licenses, thus providing space for the rapid growth of generic drugs in India. At the same time, the Indian government also stipulates that the pre-tax profit of pharmaceutical enterprises shall not exceed 15% of the drug price. 1970- 1995, India cancelled the patent of medical products and became the country with the lowest drug price in the world. In 2005, the Indian patent law was amended accordingly, so that Indian generic drugs can even be exported to regions and countries without relevant production capacity under compulsory license. What does the so-called compulsory license mean? India's patent law stipulates that local pharmaceutical companies can apply to the Indian government for compulsory license of intellectual property rights if they can't get it, can't afford it or can't provide it properly, that is, the Indian government will compulsory license their domestic pharmaceutical companies to obtain the production and sales rights of generic drugs.
Theoretically, according to the laws prevailing all over the world, the patent protection period of patented drugs is 20 years, but the Indian government can't wait for the protection period of 20 years and has implemented a special patent compulsory licensing system. That is, under special circumstances, the Indian government grants the license to use patents without the consent of the patentee, not other enterprises holding patents. In other words, the Indian government allows drugs to be directly copied.
This greatly saves the corresponding time. Then, as long as generic drugs meet the corresponding regulations, India can be legally listed and sold. From a legal point of view, India's laws are still in judicial practice, and some corresponding protection has been given to generic drugs.
