XY is a highly acclaimed Indian musician and composer, celebrated for his unique ability to blend traditional Indian music with modern technology. With a background in classical Indian music and cutting-edge music production techniques, XY has earned a reputation for creating innovative soundscapes that fuse ancient melodies with contemporary sounds. XY composed a new melody titled "XY Symphony," a fusion of Indian classical raags and modern electronic elements. This composition was the center piece of his upcoming album and was expected to revolutionize Indian fusion music. XY took meticulous care to develop this melody, intending to keep its arrangement and specific musical notations confidential until the official release. To protect his creation, XY trademarked "XY Symphony" and registered it with the Intellectual Property office. Non-disclosure agreements (NDAs) were signed by everyone involved to prevent leaks. Despite XY's precautions, a portion of the melody from "XY Symphony" was leaked. It later emerged that a former collaborator had used AI tools to analyze the melody, then applied AI-based music generation software to replicate and alter the original tune and released online through various streaming platforms. The use of AI to reverse-engineer and modify XY's melody posed a significant threat to his intellectual property. The AI-altered song bore a striking resemblance to "XY Symphony," causing confusion among listeners and threatening XY's originality and market value. XY's legal team discovered that the AI-generated version of his melody had gained popularity and was being shared across digital platforms and claimed AI-generated song was entirely original. XY filed a lawsuit under the Copyright Act of 1957, claiming that the AI-generated melody constituted an infringement of his original copyrighted work. XY also leveraged the Information Technology Act, 2000 (IT Act), focusing on the unauthorized access and misuse of digital data. The court issued a temporary injunction, ordering the removal of the AI-generated song from digital platforms. The court also allowed for an independent examination of both XY's original melody and the AI-generated version to assess the degree of similarity. XY's legal team sought financial damages for the unauthorized use of his melody and the potential loss of revenue due to the confusion caused by the AI-generated song. The court ruled in XY's favour, concluding that the AI-generated melody was derived from the original "XY Symphony." The infringing artist and producer were ordered to compensate XY for damages and were prohibited from further distributing the song.
