Immediately before the Beijing-Shanghai railway was built, the Chinese Ministry for Railways initiated international patent claims concerning the technology used in the CRH380A. It is believed that China has now filed for 21 patents in accordance with the Patent Cooperation Treaty (PCT), with the aim of obtaining patents in Japan, the United States, Brazil, Europe, and Russia.
带着这些顾虑，JR东日本继续向中国出口新干线技术。但不幸的是，中国铁道部却发起了关于CRH380A机车相关技术的国际专利申请。据信中国目前已经依照《专利合作条约》提交了21项专利，试图在日本、美国、巴西，欧洲和俄罗斯等地注册相关专利。
