国内外胶囊内镜重点创新企业专利对比分析

Comparative analysis of patents from key innovative enterprises in capsule endoscopy at home and abroad

目的分析国内外胶囊内镜(capsule endoscopy,CE)重点创新企业专利发展态势,为我国CE技术领域专利布局和发展方向提供参考。方法选取美敦力、奥林巴斯、安翰科技和金山科技作为国内外CE创新主体代表,基于Derwent Innovation(DI)数据库和IncoPat全球专利文献数据库,构建CE重点创新企业专利文献数据集,分析4家企业专利发展的特点和差异。结果从专利申请态势看,奥林巴斯全球首个专利申请时间最早(1978年),最高年申请数量为213件。从目标市场区域看,美敦力以美国为主(271件),奥林巴斯以日本为主(954件),安翰科技和金山科技均以中国为主(380件、397件)。从技术重点分布看,美敦力、奥林巴斯、安翰科技、金山科技在图像采集布局的专利数量分别为125件、392件、78件、77件,在磁控胶囊布局的专利数量分别为47件、281件、106件、102件。从近期技术热点分布看,美敦力和奥林巴斯聚焦于消化壁结构成像、图像处理、胶囊小肠镜等领域,安翰科技、金山科技聚焦于靶向给药、电池技术等领域。结论国外胶囊内镜创新企业研发起步早,专利申请数量多,全球化布局广。国内胶囊内镜创新企业虽处于技术积累的成长阶段,但发展势头快,在一些细分领域具有一定赶超趋势。

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.
