“Is the shape of a London taxi a valid registered trade mark?” is how the Court of Appeal began its judgment and is the question at the heart of the dispute between two London taxi manufacturers. Ultimately, the Court answered that question in the negative, upholding the High Court’s earlier decision which found that The London Taxi Corporation’s 3D trade mark registrations for the shape of their taxis were not valid and that a third party’s new taxi design neither infringed those invalid registrations nor constituted passing off.
