The firm was involved in the development of the railways in Southern England through its historic relationship with Isambard Kingdom Brunel and the Great Western Railway.^[4]

Osborne Clarke was founded in Bristol, England, in 1748 by Jeremiah Osborne. In 1987 Osborne Clarke opened its first London office. Over the next decade the firm opened offices in Reading, Cologne, Munich and Silicon Valley.

The law firm played a significant part in the development of the railways in the UK when it was appointed to represent the Great Western Railway Company, working closely with Isambard Kingdom Brunel on the establishment of the Great Western Main Line route from London Paddington to Bristol and the West Country.^[5] The nature of the relationship between Osborne Clarke and Brunel is best highlighted by one notable occasion when Jeremiah Osborne the Third (grandson to the founder) is said to have personally rowed Brunel down the River Avon to survey the bank for the route of the Great Western Railway.^[6]

The partnership's recent history has been characterised by two strands of development. Firstly, they have undertaken significant international expansion, particularly into the United States and Germany where they are now the 41st largest law firm.^[7] On 9 July 2012 the firm announced that two European firms, SLA Studio Legale Associato in Italy and Spanish firm Osborne Clarke Spain, had become part of Osborne Clarke.^[8]

After expanding significantly through the dot-com bubble of the late nineties and early 2000s, the firm has undergone a comprehensive restructure.
