In intellectual property law, the concepts of “composer”, “author”, “inventor”, “originality”, “inventiveness” or “state-of-the-art” are commonly use. The introduction of artificial intelligence challenges this terminology. Take music for instance. What could happen to IP rights when an algorithm compose by the aggregation of existing musics? Could a algorithm be an author? If not, who owns the rights? Who owns the results or the solution identified by an AI system? Who takes the decision of commercialization?
