發(fā)布時間：2019-01-27 08:48
【摘要】：【目的/意義】通過對全球聚酰亞胺中空纖維專利情報進行分析,揭示相關領域的發(fā)展方向,為我國在該領域的技術發(fā)展提供信息參考。【方法/過程】本文利用Innography專利檢索和分析平臺,對全球聚酰亞胺(PI)中空纖維專利情報進行分析,內容包括專利申請趨勢分析、技術應用國分布、技術發(fā)明國分布、專利權人分析、專利價值評價等。利用Innography新的分析功能對聚酰亞胺(PI)中空纖維專利技術申請量TOP5機構的研究熱點、專利布局進行了分析,對比國外競爭對手研發(fā)熱點,為國內研發(fā)方向提供參考。對挖掘出的核心專利內容進行了分析探究�！窘Y果/結論】分析結果表明,美國、日本、德國、韓國、法國等在聚酰亞胺中空纖維領域的技術實力較強,擁有各自獨特的核心專利內容。中國雖然是該項技術的主要應用國和技術發(fā)明國,但尚未擁有核心專利。目前聚酰亞胺中空纖維的研究熱點主要為用于氣體分離的中空纖維膜的制備和應用。
[Abstract]:[objective / significance] through the analysis of patent information on polyimide hollow fiber worldwide, to reveal the development direction of related fields, This paper analyzes the patent information of global polyimide (PI) hollow fiber by using Innography patent retrieval and analysis platform, including patent application trend analysis. Technology application country distribution, technology invention country distribution, patent owner analysis, patent value evaluation, etc. The research focus and patent layout of polyimide (PI) hollow fiber patent application volume (TOP5) are analyzed by using the new analysis function of Innography. The research hotspots of foreign competitors are compared and the reference for domestic research and development is provided. The core patent contents are analyzed and explored. [results / conclusions] the results show that the United States, Japan, Germany, South Korea, France and other countries have strong technical strength in the field of polyimide hollow fibers. Has their own unique core patent content. Although China is the main application and invention country of the technology, it does not have the core patent. At present, the research focus of polyimide hollow fiber is the preparation and application of hollow fiber membrane for gas separation.
