摘要
通过对中国发明专利进行数据挖掘和计量分析,总结了碳纳米管技术及应用的专利申请情况,结果表明,碳纳米管技术处于高速发展阶段,高等院校和企业申请了大量的专利。通过国际专利分类信息(IPC)研究了重点高等院校和企业申请人的专利技术布局。结合专利申请年份跨度及专利法律状态信息,总结重点专利持有人的技术研发实力和近期技术投入力度。
Based on Chinese patents of invention, with data mining and patentometric analysis, an overview of carbon nanotube and its applications is presented. The nanotube technology in China has entered a fast development stage. The core technology distributions of patent applicants, especially the universities and companies, are demonstrated with international patent classification（IPC）. By analyzing the patent legal status and application date range, the R＆D strength of key assignees and their commitment to carbon nanotube technology are summarized as well.
