The image of the TARDIS has become firmly linked to the show in the public's consciousness; BBC scriptwriter Anthony Coburn, who lived in the resort of Herne Bay, Kent, was one of the people who conceived the idea of a police box as a time machine. In 1996, the BBC applied for a trade mark to use the TARDIS' blue police box design in merchandising associated with Doctor Who. In 1998, the Metropolitan Police Authority filed an objection to the trade mark claim; but in 2002, the Patent Office ruled in favour of the BBC.
