The Patent Office - now the Intellectual Property Office - was established by the Patent Law Amendment Act of 1852, which simplified the procedure for obtaining patents of invention and reduced costs. In 1883 another Act of Parliament brought into being the office of Comptroller General of Patents, with, according to the National Archives, 'a staff of patent examiners to carry out a limited form of examination; mainly to ensure that the specification described the invention properly, but without any investigation into novelty'.
