摘　　要：从国内相关银氧化锡电触头材料制备领域的专利文献中获取发展动态。采集1986年5月13日至2013年6月25日期间的国内银氧化锡电触头工业技术专利文献,建立专利数据库。通过可视化的方式,从专利申请量、专利分布、专利技术和专利持有人、专利技术生命周期等方面等角度深入分析了银氧化锡电触头材料制备领域专利的整体申请概况和主要申请机构等情况。通过研究发现关于银氧化锡电触头材料的专利技术周期包括快速增长期、成熟期和衰退期,缺乏专利的萌芽期,这可能与我国触头材料行业大多采用参照国外已有技术进行产品试制有关。In this paper, with development trend obtained from related patent documents concerning manufacturing technology of AgSnO2 electric contact materials in China,patent analysis is used as the basic approach.The domestic patents of AgSnO2 industrial technology from May 13, 1986 to June 25, 2013 were collected and the associated patent database was established. Through the visual way the whole patent application situation, and main patent application agencies and so on were analyzed through statistic analysis of patent application quantity, patent classification, patent distribution, the patent technology, patent holders, and technology life cycle etc. Through the study,we found that the technology life cycle of AgSnO2 contact materials includes technology rise period, mature period and declining period. And the phenomenon of Chinese contact industry copied to foreign company＇s technology may be lacking the sprouting period.
