基于应用领域视角的技术发展态势分析内容和方法——以石墨烯传感器技术为例

Content and Method of Analysis on Technology Development Trend from Perspective of Application Field:Graphene Sensor Technology as Example

从应用领域的视角,提出分析技术发展态势的内容和方法,即首先利用专利信息和语义分析方法识别技术应用领域,然后从专利分布、专利权人和知识产权风险3个方面分析技术在不同应用领域的发展态势。以石墨烯传感器技术为例,分析了该技术在中国9个领域的发展态势以及在结构材料和电极领域的知识产权风险情况。

This paper proposes the content and method of analysis on technology development trend from the perspective of application field. First,identifying the application fields of technology by using patent information and semantic analysis method;then analyzing the develop- ment trend of technology in different application fields separately from three aspects, namely patent distribution, patentee and intellectual property right risk. Taking the graphene sensor technology as the example, it analyzes the development trend of this technology in nine application fields,and the intellectual property right risks in the fields of structural material and electrode.
