Beijing Meishe Network Technology Co., Ltd. filed a formal lawsuit against ByteDance, Beijing Microseeding Horizon Technology Co., Ltd., and several affiliated companies on the grounds of the infringement of computer software copyright and technical secrets. Meishe demanded that the aforementioned companies immediately stop infringements, apologize publicly on their own media outlets for the alleged wrongdoings, and pay 2.274 billion RMB as compensation for its economic losses.

Through comparison, Meishe found that since the Douyin version 3.0 launched on November 1, 2018, Douyin owner ByteDance has been copying Meishe’s programming related to realizing audio and video editing and processing functions. Video and audio editing and processing functions are one of the most basic and core functions of Douyin. Based on this function, several apps including Douyin have secured hundreds of millions of users and have been downloaded billions of times. Huge profits have been obtained from the infringements.

In accordance with the "Copyright Law of the People's Republic of China", "Anti-Unfair Competition Law of the People's Republic of China", "Regulations for the Protection of Computer Software" and other relevant laws and regulations, Meishe has filed a lawsuit with the court.
