摘要
从专利分析的角度,对欧洲地区与中国地区的动车技术的发展态势、地域布局、技术布局和重点申请人进行对比分析。研究结果表明,欧洲地区的动车技术发展已趋于成熟,近年来发展较为缓慢,而中国地区的动车技术发展正处于快速上升期;西门子、庞巴迪和阿尔斯通的专利布局策略较为全面,对于欧洲地区较为重视,且兼顾中国地区,而中国中车集团有限公司目前仅对于中国地区的专利布局较为重视,在欧洲地区还需加强专利布局。
From the perspective of patent analysis,the development trend,regional layout,technical layout and key applicants of the EMU technology in Europe and China are compared and analyzed.The research results show that though the development of EMU technology in Europe has become mature,the technology development is slowing down in recent years,while in China the EMU technology development just enters a period of rapid rise.The patent layout strategies of Siemens,Bombardier and ALSTOM are comprehensive,they pay more attention to Europe but take account of China at the same time.Since CRRC(China Railway Rolling Stock Corporation)pays more attention only to the patent layout in China,its patent layout strategy in Europe needs to be strengthened.
