Generative AI raises a host of interesting legal issues, but perhaps none will be more contentious than the intersection between copyright and services such as ChatGPT. The copyright questions apply both the creation of large language models used to train these systems as well as the copyright associated with outputs. These questions have sparked high profile class action lawsuits and government consultations on potential reform. Andres Guadamuz is a Reader in Intellectual Property Law at the University of Sussex and the Editor in Chief of the Journal of World Intellectual Property. He joins the Law Bytes podcast to explain the copyright implications of generative AI and to unpack the claims found in the copyright class action lawsuits.
