From its early days, the Patent Office was based in the
Chancery Lane area of London, where it eventually spread to fill the area between Furnival Street and Southampton Buildings. The principal entrance was at 25 Southampton Buildings, where a purpose-built headquarters was constructed in 1899–1902 (architect: Sir
John Taylor). The principal interior space was the Library, a "harsh but spectacular space 140ft long, lit from skylights and a
clerestory, with two tiers of steel-framed, fireproofed galleries on cast iron
Corinthian columns". Designed to allow members of the public to consult patent records, it also contained a very extensive collection of technical and scientific publications, which in 1967 was transferred to the
British Library. In 1991, having outgrown its original premises, the Patent Office moved to
Newport,
South East Wales, where the IPO headquarters remains to this day. A small branch office in London has been maintained for the benefit of the large professional community based there and for communication with central government. == See also ==
