Core Viewpoint - The case highlights the legal responsibilities of online store registrants, even if they are not the actual operators, in cases of copyright infringement involving unauthorized sales of digital content [1][2]. Group 1: Legal Responsibilities - The court ruled that both the registered owner (Sun) and the actual operator (Lin) of the online store are liable for copyright infringement due to the unauthorized sale of a professional exam course [1][2]. - Sun, as the registered operator, had the obligation to ensure the store operated legally and failed to change the registration after leasing it to Lin, thus sharing liability for the infringement [2]. Group 2: Infringement Patterns - The case illustrates a growing trend of "shell operations," where individuals rent or use others' identities to operate online stores selling pirated products, which poses significant legal risks [2]. - The court emphasized the need for vigilance against such practices, as registered owners may still bear legal responsibility for infringements occurring under their name [2][3]. Group 3: Recommendations - It is advised that individuals should not casually rent out their online stores or disclose personal identity information, as this can lead to legal complications [3]. - Registered owners who lease their stores should maintain oversight to ensure compliance with legal standards and promptly change registration if they no longer wish to operate the store [3].
