基于专利分析的石墨烯技术态势研究

Research on graphene technical situation based on patent analysis

在对石墨烯材料特性、制备、发展态势概述的基础上,以orbit专利数据库为数据源,通过对石墨烯专利申请量、技术领域、专利权人、专利地图和专利被引量等指标的定性分析,研究石墨烯产业的发展趋势、技术特点、主要竞争者和整体专利布局。采用定性与定量相结合,以事实性数据结合石墨烯产业的整体态势,分析目前的石墨烯技术难点和瓶颈问题,并提出建议。

The preparation,characteristics,development situation of graphene materials were researched.On the basis of the orbit patent database,grapheme patent was qualitatively analyzed,through the patent applications,technology,patent holder,patent map and the patent cited amount.Then,it could reflect the graphene industry trends,technical characteristics,main competitors and the whole patent layout.The combination of qualitative and quantitative data,and combined with graphene industry situation,the current technical difficulties and bottlenecks were analyzed.The suggestions were put forward.
