There are three types of online copyright cases: 1. Infringing the work itself: If the author did not obtain the authorization of the copyright owner when creating the work and uploaded his work to the Internet or other platforms without the consent of the copyright owner, the uploader may constitute the copyright itself. For example, uploading someone else's work to one's own website without the authorization of the copyright owner or publicly publishing someone else's work without authorization. 2. Infringements of adaptation, translation, and interpretation of works: If the adaptation, translation, and interpretation of another person's work are done without the consent of the copyright owner, it may also constitute an copyright violation. For example, adapting someone else's work into one's own work or performing someone else's work into one's own work without authorization. 3. Transmission of works of copyright: If the works of others are transmitted to the Internet or other platforms without the consent of the copyright owner, the communicator may also constitute the copyright of the work itself. For example, uploading someone else's work to one's own website without authorization or publicly publishing someone else's work for commercial purposes without authorization. It is important to note that the judgment of online copyright violation cases may vary according to the specific circumstances. Therefore, it is recommended to immediately stop the violation when it occurs and actively express your apology to the copyright owner. At the same time, it is recommended to actively protect their legitimate rights and interests through legal means to pursue the legal responsibility of the perpetrator.
