Dr John Liddicoat is a senior lecturer at The Dickson Poon School of Law, King’s College London.

John is broadly interested in the development and use of new technology as it has the ability to: drive economies forward, increase public welfare and resolve important social problems. Much of his research focuses on the ability of patent law to meet its welfare-enhancing goal of accelerating the creation of new technology. In biotechnology and life-sciences — special interests of his — this focus is particularly important, but it is also complicated; although patents can operate as incentives, they have numerous trade-offs.

Smart innovation policy requires meticulous, transnational doctrinal research and robust empirical data. As a lawyer with scientific training, John strives to deliver both and have developed numerous new methods using novel data. His research has been funded by the Wellcome Trust, the Philomathia Foundation, and Cancer Research UK, amongst others.
