Copyright Infringement — Substantial Similarity is the unauthorized use of a copyrighted work that is so similar to the copyrighted work that it could be mistaken for the original work. This type of copyright infringement is also sometimes referred to as piracy. It is a violation of the copyright holder's exclusive rights, including the right to reproduce, distribute, display, or create derivative works. There are three types of Copyright Infringement — Substantial Similarity: 1. Direct Infringement: This occurs when an unauthorized copy of a copyrighted work is made without the copyright holder's permission. 2. Indirect Infringement: This occurs when someone uses a copyrighted work in a way that does not directly copy the work, but is still substantially similar. 3. Contributory Infringement: This occurs when someone is not directly infringing, but they are contributing to an infringement by providing the means to do so.
