国内外胶囊内镜重点创新企业专利对比分析OA北大核心CSTPCD

Objective To analyze the patent development trends of key innovative enterprises in capsule endoscopy(CE)both domestically and internationally,providing insights for the patent layout and development direction in China's CE technology sector.Methods Medtronic,Olympus,Anhan Technology and Jinshan Science and Technology were selected as representatives of major CE innovators.Based on Derwent Innovation(DI)database and IncoPat global patent database,a patent literature dataset of key innovative enterprises in CE was constructed to analyze the characteristics and differences in patent development among the four enterprises.Results From the perspective of patent application trends,Olympus had the earliest global patent application(1978),with the highest annual application number(213).In terms of target markets,Medtronic primarily focuses on the United States(271 cases),Olympus on Japan(954 cases),and Anhan Technology and Jinshan Technology both on China(380 cases and 397 cases,respectively).Regarding the distribution of subdivided technological focuses,Medtronic,Olympus,Anhan Technology,and Jinshan Technology hold 125,392,78,and 77 patents respectively for image acquisition,and 47,281,106,and 102 patents respectively for magnetically controlled capsules.From the perspective of technological hotspot distribution,Medtronic and Olympus pay attention to digestive wall structure imaging,image processing,and capsule enteroscopy,while Anhan Technology and Jinshan Technology focus on targeted drug delivery and battery technology.Conclusions International innovators in capsule endoscopy started their R&D earlier,resulting in a large number of patents and a broader global layout.Although domestic capsule endoscopy innovation companies are in the growth stage of technological accumulation,they have a fast development momentum and show a certain trend of catching up in some sub-technical fields.
