Analysis On The Evolution Of Shanghai Biomedical Industry Based On Patent Thicket

In recent years,Shanghai's biomedical industry has developed rapidly,and its industrial innovation capability has also reached a relatively high level.This article takes the Shanghai biomedical industry as the research object,focuses on the process of industrial development and evolution from the perspective of patents and patent thicket,uses patent data retrieved from the inco Pat technology innovation information platform,applies patent measurement analysis and cooperation network analysis,etc.,combined with R language Handle raw data format,Citespace cooperation network visualization,Ucinet network density measurement and other methods,try to describe the current status of patent development in the biomedical industry in Shanghai,and try to measure the existence and evolution stage of the "patent thicket" phenomenon in the industry with the common citation relationship of patents Divide,combine patent indicators and policy factors,and try to interpret the characteristics and causes of each evolution stage of the "patent thicket"The study found that the Shanghai biomedical industry has developed rapidly and has formed a relatively complete industrial innovation cluster,but the innovation cooperation model is relatively single and the level of patent conversion still needs to be improved;The Shanghai biomedical industry has gone through the "patent thicket" preparation and growth stage,is in the stable stage of the "patent thicket",and the characteristics of the evolution stage of the "patent thicket" are closely related to the industrial development process.Therefore,it is necessary to consider how to achieve the healthy development of the biomedical industry innovation while avoiding the intensive “patent thicket” as much as possible.This article believes that companies should pay attention to patent applications and expand their own patent portfolios,pay attention to early warning of corporate patents,and actively seek protection from patent alliances.Shanghai is actively introducing biomedical companies and actively planning biomedical industry clusters while paying attention to their patent innovation Capability and patent distribution.
