摘要
目的:揭示3D生物打印产业技术研发态势和专利布局,以期为相关机构提供竞争情报,为行业发展提供数据支撑。方法:基于3D生物打印领域产业调研和技术分解,构造检索式获取数据,多维度量化分析领域专利。结果:3D生物打印产业发展可分为孕育期、萌芽期和高速发展期;该产业集中度较低,处于分散竞争阶段;申请人多依据地缘因素选择合作对象,合作方之间多为不同类型的机构;中国申请人的专利申请量占全球的比重已接近50%,但美国申请人的专利篇均被引频次仍远超中国;美国申请人更关注海外市场。结论:3D生物打印产业尚未形成规模效应,有必要整合业内资源,打造产业集群;中、美两国在该产业都具有优势地位,中国亟待加强海外专利布局;综合权衡专利数量和质量,美国申请人的专利竞争力仍高于中国,中国需培育更多核心专利。
Objective:The purpose is to reveal the research and technology development and patent layout of the 3 D bioprinting industry,in order to provide competitive intelligence service for relevant institutions and data support for the development of the industry.Methods:Based on industry research and technology decomposition in the field of 3 D bioprinting,we constructed queries to obtain data,and quantitatively analyzed relevant patents in multiple dimensions.Results:The development of 3 D bioprinting industry can be divided into gestation period,budding period and high-speed development period;this industry has a low concentration and is in the stage of decentralized competition;applicants mostly choose partners based on geographical factors,and the partners are mostly different types of institutions;Chinese applicants account for nearly 50%of the world’s patent applications,but the average frequency of patent citations of American applicants is still far higher than that of China;American applicants pay more attention to overseas markets.Conclusion:A scale effect has not yet existed in 3 D bioprinting industry,so it is necessary to integrate industry resources and build industrial clusters.Both China and the United States have dominant positions in this field,but China urgently needs to strengthen the layout of overseas patents.Taking into account the number and quality of patents,the patent competitiveness of US applicants is still higher than that of China,so China needs to strengthen the cultivation of core patents.
