国外来华交通工程领域专利分析

Analysis on domestic foreign patent in traffic engineering

在中国对外开放及国际技术交流规模扩大的背景下,分析发达国家来华专利布局,可向我国相关企业提供行业技术情报,为企业制定专利发展战略和对策提供参考。为了解交通工程领域国外在华专利布局情况,采用分类号与关键词相结合的方法检索了欧盟、美国、日本、韩国4个国家或地区交通工程领域来华专利文献,建立了交通工程来华专利数据库,分析了交通工程来华专利申请趋势以及近年来交通工程领域技术热点,最后从国家、行业、企业3个层面给出了公路行业交通工程领域专利发展战略与对策。

Under the background of China＇s opening up to the outside world and the expansion of international technology exchanges, the analysis of the patent distribution of developed countries to China can provide industry technical information to relevant companies in China and provide reference for enterprises to formulate patent development strategies and countermeasures. In order to understand the situation of foreign patents in China in the field of traffic engineering, a method of combining the classification number with the keywords was used to retrieve patent documents from the four countries or regions of the European Union, the United States, Japan, and South Korea. The patent database analyzes the trend of patent applications for traffic engineering in China and the technical fronts in the field of traffic engineering technology in recent years. Finally, the development strategies and countermeasures for the patents in the field of traffic engineering in the highway industry are given from three levels： national, industry, and corporate.
