基于专利信息的水性聚氨酯全球发展现状及对策分析

Global development status and countermeasures of waterborne polyurethane based on patent information

通过检索水性聚氨酯行业的专利信息,分析了该领域全球发明专利申请趋势、专利地域布局、专利技术来源、全球主要核心申请人、主要技术构成等,并对该领域的经典专利进行了剖析。研究结果表明:我国水性聚氨酯发明专利申请量早已超过美国,成为世界第一,并一直保持领先。但相对于德国、美国,我国专利整体价值不高,体现在应用领域的专利布局较多而合成制备领域的布局较少,同时国内企业对海外专利的布局也较少。因此建议国内申请人应注重主要技术专利在国内外的合理布局,另一方面应强化水性聚氨酯基础研究层面的专利申请。

By searching the patent information of the waterborne polyurethane industry,the global invention patent application trend,patent geographical layout,patent technology source,global main core applicants,main technology composition,etc. in this field were analyzed,and the classic patents in this field were investigated. The research results show that China′ s waterborne polyurethane invention patent applications have long surpassed the United States,becoming the world′s first,and has always maintained a leading position. However,compared with Germany and the United States,the overall value of China′s patents is not high,which is reflected in the application field of more patent layouts and less layout in the field of synthesis preparation,and Chinese enterprises have less layout of overseas patents. Therefore,it is suggested that domestic applicants should pay attention to the reasonable layout of major technology patents at home and abroad,and on the other hand,strengthen patent applications at the basic research level of waterborne polyurethane.
