Abstract
This chapter explores the issue of patent ownership and the related question of who is entitled to be granted the patent. It begins by considering aspects of British law dealing with ownership and who is properly entitled to the grant of a patent as well as the remedies available where the wrong person has applied for a patent or a patent has been granted to the wrong person. It then analyses in detail who counts as an inventor, issues surrounding inventions allegedly produced by artificial intelligence, joint inventors, and entitlement issues that arise in relation to inventions created by employees.
