The conditions for compulsory patent licensing are as follows

The main reason of compulsory license is that the patentee abuses power and public interests. The purpose of the patent law itself is to promote the development of science and technology, so when the behavior of the right holder hinders the development of science and technology or has greater interests to protect, the patent right is restricted to a certain extent, that is, the patent compulsory license. Compulsory patent license refers to the patent license issued by the patent administration department according to the conditions and procedures prescribed by law. After obtaining this license, the applicant may exploit his patent without the consent of the patentee, but he shall pay the patentee a reasonable royalty. The object of compulsory license only refers to patents for inventions and utility models, excluding designs.
