Abstract: 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.
