摘要
选择"七国两组织"中文专利数据库,采集1985年1月1日到2008年12月31日期间的LED信号显示技术专利文献,建立专利数据库。再选择广东专利信息服务平台分析系统分别从专利申请总量、重点专利技术和重点专利持有人等方面,对LED信号显示技术专利进行了深入的分析,并对比分析了国内外LED信号显示技术专利现状,提出了发展我国LED信号显示技术的专利策略。
＂The seven countries and two organizations＂ patent database was chosen,LED signal display technology patents between January 1 1985 to December 31 2008 were collected and the associated patent database was established. Guangdong patent information service platform analysis system was chosen. These LED signal display technology patents were analyzed deeply from the total amount of patent applications, key LED patents and key patent holders respectively. The present patent status of abroad and China＇s are compared. The patent strategy of developing our nation＇s LED signal display technology is also discussed.
