Abstract: Objective To establish a system conducive to generic drug companies based on the facts that although China has promised to implement the data monopoly system and patent term extension system for pharmaceutical companies that hold the patents, yet China is a country that manufactures a large number of generic drugs each year which are closely related to citizens’ healthcare. Methods The US drug patent linkage system was studied through literature review methods and then the protection of the interests of generic drug companies in the drug-patent linkage system was explored based on the Cournot model. Results and Conclusion The policy of improving the quality of generic drugs and increasing the spillover effect of technology is more beneficial to generic drug companies. Based on the results, some policy suggestions are put forward, such as the implementation of the simplified application system for generic drugs and the consistency evaluation of generic drugs.
