Introduction The purpose of this Practice Notice is to consider the issues arising in relation to the development, implementation and use of generative artificial intelligence (GenAI) technologies in so far as they relate to the ownership and protection of relevant IP rights. This includes consideration of the ownership and use of IP-protected materials in the training of GenAI models (including issues around text and data mining (TDM)), consideration of the IP rights that might arise in relation to the prompts that are given to GenAI systems, ownership of IP in the technology of the AI system itself, and ownership of the content that the GenAI system produces. What is GenAI? GenAI is an umbrella term for all AI models capable of generating or creating new and original material, which may include text, code, images, audio, or video. The exact definition of GenAI is not universally agreed.
