医疗健康信息领域区块链技术专利的应用发展态势研究

Research on the application and development trend of blockchain technology to patents in the field of medical and health information

目的对全球范围内医疗健康信息领域区块链技术专利进行分析。方法基于Orbit专利数据库中2009年至2020年该领域的专利数据,采取专利分析法和社会网络分析法对申请态势、技术研发机构分布、研发重点领域和合作网络进行深度挖掘分析。结果共获得全球范围内医疗健康信息领域区块链技术发明专利样本数据1927条,有效专利1660件(86.1%)。中国专利公开数量最多(615件),但美国专利优先权数量最多(1031件),美国专利申请机构全球布局意识强。区块链技术已应用于医疗保健信息学、电数字数据处理、数字信息的传输、诊断与鉴定等多个领域。结论医疗健康信息领域区块链技术处于快速发展期,我国应加强专利全球布局意识,进一步加强数据识别、数据表示、记录载体、传输装置等技术的研发与合作。

Objective To analyze the patents of blockchain technology in the field of medical and health information worldwide.Methods Based on the blockchain patent data in this field from 2009 to 2020 in the Orbit patent database,both patent and social network analysis were used to analyze the application situation,distribution of research and development institutions,key areas and cooperation networks.Results A total of 1,927 invention patent samples of blockchain technology in the field of medical and health information were obtained,and 1,660 valid patents(86.1%)were obtained.China is the country with the largest number of patents(615),but the United States is the country with the largest number of patent priorities(1,031).Blockchain technology has been applied in many fields,such as healthcare informatics,electronic digital data processing,digital information transmission,diagnosis and identification.Conclusion Blockchain technology in the field of medical and health information is undergoing a period of rapid development.China should enhance the awareness of the global patent layout,and further consolidate the technological research and development,and cooperation in data identification,data representation and record carrier,transmission devices.
