1. It is not advisable for drugs to be monopolized by patents. First of all, drugs serve patients all over the world, and monopoly runs counter to this;

2. There is a famous "Double Ten" law in the medical field: it takes 65.438+0 billion dollars and 654.38+0 years to develop a new drug. Moreover, with the increasingly strict regulatory regulations of the pharmaceutical industry and the continuous development of available targets by predecessors, the difficulty of new drug research and development is also increasing year by year. At present, the research and development time of a new drug is close to 15 years, and the investment in research and development is close to $2 billion. As a patented drug with a large investment, it is understandable to recover the staged monopoly right.

3. A new drug has to go through three stages of trial before it goes on the market, and each stage may fail. Some of them have a good effect when they are clearly studied, but they have no effect at all in clinic, which is too normal. It is not surprising to apply for a patent and monopolize it after successful research and development.
