The Yi mirrorless camera M1 is the latest product launched by Shanghai Yi Technology Co., Ltd. (hereinafter referred to as "Yi Technology"). As an "Internet hardware company" under the Xiaomi ecological chain, Xiaoyi Technology has previously launched smart cameras, driving recorders, action cameras and other products. With the launch of Xiaoyi's mirrorless camera on September 19, a Weibo post that night was widely circulated on the Internet: "Mirrorless is our company's registered trademark in Greater China. Your company's advertising words have caused infringement. Our company has started to prepare litigation materials and will submit them to the People's Court in the near future. During the litigation, our company will stop supplying CMOS to your company, please know." According to the screenshot of the Weibo content, the above content was signed by "Sony China". It was posted on Weibo, but the Rule of Law Weekend reporter did not find the above content on the official Weibo of "Sony China". Subsequently, news pointed out that the Weibo content was not officially issued by Sony, but was simply written by Weibo netizens. The Rule of Law Weekend reporter found that the above-mentioned Weibo content comes from Weibo user "rauljolin", whose identity profile is "Guangdong Jinshi Media Group, Gangsi, controlled by Sony." Regarding the authenticity of the content on Weibo, the Rule of Law Weekend reporter wanted to interview Sony. As of the time of publication, no reply has been received from Sony. The Rule of Law Weekend reporter also interviewed Xiaoyi Technology. A staff member of the Public Relations Department of Xiaoyi Technology told Rule of Law Weekend Reporter, as far as he knows, Sony China has never issued a statement on this. The above Weibo content may be jokes and rumors compiled by netizens.

However, the massive dissemination of this Weibo content triggered widespread doubts among netizens about the legitimacy of the use of the word "Mirrorless" in the product name and promotion of Xiaoyi's mirrorless cameras. Many netizens commented on Weibo and Tieba that since the word "Mirrorless" has become a registered trademark of Sony, the continued use of Xiaoyi's mirrorless cameras is suspected of infringement. In the face of doubts from netizens, on September 20, the official Weibo account of Yi Mirrorless Camera responded, stating that Sony’s “Mirror Single Camera” trademark for the camera category is in the process of application and has not yet been registered, so there is no infringement; “Mirror Single Camera” These two words are actually common names for a certain type of camera, and are not inappropriate when used in product descriptions.
