【 摘 要 】

In order to clarify the technical layout and development trend of fluorine pollution control technology in China, this paper analyzes the patent applications related to domestic fluorine pollution control from 1985 based on the SooPAT patent search database. It also reveals the overall development trend of patent technology in this field. This paper concretely analyzes the annual changes trend of the patent, the legal status of the patent, the focus of technology research and layout, patent-related subjects. Finally, this paper summarizes the fluorine pollution control technology on the base of patent data analysis.
