This Practice Note discusses the interplay between artificial intelligence (AI) (or machine learning) and intellectual property (IP). First, it explains what AI is and its use in different sectors before considering the implications of AI for the development of IP law, including the protection of: training data, training algorithms, AI systems themselves, and the output of AI. It then looks at the issues to consider when contracting with a third party AI solution provider and whether changes to the current IP system are necessary to deal with AI.
