摘　　要：本文对高纯铟领域的专利申请情况进行定性和定量分析,发现我国专利申请数量超过日本等其他国家,成为专利申请数量最多的国家,但未形成有利的专利壁垒,并且我国高纯铟专利产出主要以原生铟提纯为主,而国外专利产出以再生铟的提纯回收为主。我国作为铟的消费大国,从铟资源的长远发展战略考虑,我国应该大力加强再生铟回收制备高纯铟的技术研究与应用,确保我国铟资源的可持续发展。This paper makes a qualitative and quantitative analysis on the patent applications in the field of high-purity indium.It is found that the number of patent applications in China exceeds that in Japan and other countries,becoming the country with the largest number of patent applications,but there is no favorable patent barrier.Moreover,the patent output of high-purity indium in China is mainly the purification of primary indium,while the foreign patent output is mainly the purification and recovery of regenerated indium.As a major consumer of indium,considering the long-term development strategy of indium resources,China should vigorously strengthen the technical research and application of recovering regenerated indium to prepare high-purity indium,so as to ensure the sustainable development of indium resources in China.
