基于专利文献的纳米生物材料领域技术机会识别初探

A Preliminary Research of Identifying Technology Opportunity in Nano Biomedical Material Field Based on Patent Literatures

目的:针对当前国内生物材料市场仍被大量国外产品占据这一现状,从发明专利角度识别纳米生物材料领域内现存的技术机会,旨在服务企业及研究机构更好地开展技术创新活动。方法:应用词频分析及共词分析法,借助信息可视化工具揭示同类别(共有材料、性能、技术和产品等4大类)及不同类别词汇间的关联关系。结果:依据共词图谱结果并结合文献调研及专家咨询,发现了某些材料(如聚乳酸、纳米银、磁性纳米粒子等)、技术的新应用及其变化情况和具有潜在整合价值的技术、材料及其性能等,并从中总结出一些技术机会识别视角。结论:在实际的技术机会识别过程中,必须综合利用各种类型的科技文献信息资源,并且要意识到领域专家智慧的重要性。

Objective： Facing the status that currently foreign products have occupied the overwhelming majority of domestic biomaterial field, invention patents belonging to nano biomedical material included by Derwent Innova- tions Index（DII） database were analyzed in order to identify technology opportunities existing in this field for serv- ing technology innovation of domestic enterprises and research institutes. Methods： The association between words of the same or different categories which represented material, property, technology and product were revealed. Re- suits： Some valuable information such as a new application and its changes of certain material（for example polylac- tic acid, nano-silver and magnetic nanoparticles） or technology and some technologies, material and its properties which have potential possiblities to be intergrated together was found out according to the results of co-word knowledge map, literature investigation and expert consultation. Besides several views were summarized for identify- ing technology opportunities more exactly. Conclusion： The results showed that more kinds of S＆T literature re- sources should be used comprehensively and the importance of experts wisdom can＇t be ignored in the actual pro- cess of identifying technology opportunities in a certain research field.
