摘要
本文基于Dialog联机检索,以德温特世界专利索引数据库和专利引文索引数据库为数据源,对质子交换膜(PEM)燃料电池行业进行了专利分析研究。作者用实例说明了利用各种Dialog高级检索指令实现行业专利分析的技巧。通过分析研究,发现了PEM燃料电池行业的领先企业、技术领军人物、产业发展前景、全球技术/市场布局、关键技术、研发热点等。研究表明,Dialog?联机检索在行业专利分析中是一种有效的工具。
Based upon Dialog online search, we use Derwent World Patents Index （DWPI） and Derwent Patents Citation Index （DPCI） as data sources to analyze the patents in PEM fuel cell industry. This paper illustrates the skills of using various Dialog advanced commands for industry sector patents analysis. As a result, the industry sector leaders, pioneer experts, industrial foresight, global technology and market layouts, key technologies and recent R＆D hot spots are discovered thereby. It has been shown that Dialog online search is an effective way for analyzing all the patents in an industry sector.
