基于中国专利分析的技术情报研究——以二氧化钛光催化技术领域为例

China Patent Analysis-based Technological Information Research: Case Study of TiO_2 Photocatalysis Technology Field

[目的/意义]通过对专利文献的挖掘和分析,为我国二氧化钛光催化产业提供情报参考。[方法/过程]从专利申请量、技术生命周期、专利技术分类和专利申请主体等方面,揭示我国二氧化钛光催化技术领域的发展,并通过合作专利分析呈现该领域产学研的合作现状。[结果/结论]我国二氧化钛光催化技术仍处于快速发展期,然而企业所有的专利较少,企业技术研发实力相对较弱。绝大多数专利国内高校所有,不利于专利的转化,因此应该鼓励企业加强与高校、科研机构及个人的合作,通过专利合作平台寻找合适的技术合作伙伴,以提高企业的核心竞争力。

[Purpose/significance]This paper is to mine and analyze patent documents to offer technical information reference for TiO2 photocatalysis technological industry in China. [Method/process]The paper reveals the development of TiO2 photocatalysis tech- nology field from aspects of patent application number, technological life cycle, patent classification and patent applicants, and does a cooperative patent analysis to show industry-university-research cooperative situation of the field. [Result/conclusion]TiO2 photocatal- ysis technology industry in China is still in stage of rapid development, but number of patents owned by enterprises is low which indicates R＆D abilities of enterprise is still relatively weak; most of patents are owned by universities which is not conducive to patent＇s transformation. Therefore, it should be encouraged to strengthen cooperation between enterprises and other patent-owners, including universities, scientific research institutions and individuals, for enhancing core competitiveness of enterprises through the patent coopera- tion platform.
