采用国家知识产权局的专利检索与服务系统以及德温特世界专利索引数据库,以中国专利文献检索系统为补充,对世界航空用铝合金专利文献进行采集。对其专利申请的年度分布、主要技术、主要申请人、核心专利等进行统计分析,给出了航空用铝合金行业的专利发展趋势,帮助从业人员更好地利用专利这一技术工具,建立合理的专利布局,提高我国航空用铝合金企业在国内和国际市场上的竞争能力。
Based on National Patent Search and Service System and Derwent World Patents Index, taking China Patent Retrieval System as references, we collect the data of world patents on aviation aluminum alloys, such as annual distribution, technologies, applicants and core patents etc, to analyze the patent development in the aviation aluminum alloys market. Our works can help the practitioners to use the patents and establish reasonable patents distribution, and to strengthen the competitive ability in the world aviation aluminum alloys patent markets.
