Why does the state have the right to license the popularization and application of important invention-creation patents?

Under certain conditions, the state has the right to popularize important inventions and patents of China citizens and units, and to license other units to implement them. Why does the state have the right to license the popularization and application of important invention-creation patents? Patents that the state has the right to popularize and apply are mainly patents held by units owned by the whole people. The property ownership of units owned by the whole people belongs to the state, and so does the patent right obtained by invention and creation. The unit only has the right to hold, but has no absolute exclusive right. Therefore, the state has the right to license other units to exploit their patents according to the needs of national economic development and for the benefit of the whole people. This practice is called state permission. The State allows the relevant competent departments of the State Council and the people's governments of provinces, autonomous regions and municipalities directly under the Central Government to exercise this power. This power can be exercised over the patents of units owned by the whole people within the system or within the jurisdiction. The license should be an important invention-creation patent. In order to avoid unorganized implementation, the license will be carried out according to the national plan. Non-designated units may not implement it, otherwise the patent right will be infringed. National permission does not mean free use and eating the same pot. In order to compensate and reward the capital and labor invested by the inventor and encourage the inventor to engage in invention-creation, the Patent Law stipulates that the exploitation fee shall be paid to the entity holding the patent right in accordance with the regulations. For patents owned by collectively owned units and individuals, the state generally does not adopt the practice of licensing other units to implement them. Only when the patent is of great significance to the national interests or public interests and needs to be popularized and applied, the relevant competent authorities in the State Council can license other units to implement it after reporting it to the State Council for approval.
