2- The state grants the patentee the exclusive right for a certain period of time because he provides the public with new and useful technical solutions and enriches the existing scientific and technological treasure house. Therefore, the exclusive right to patent provided to it should be limited to its new technical scheme, and the technology that has been known to the public in the past should not be included in the patentee's rights, otherwise it will harm the public interest, affect the normal social order, and hinder the popularization and application of science and technology and the development of society.
