Early 1900s

The firm's name was changed to Bristows, Cooke and Carpmael in 1906, reflecting the names of the then partners.

Henry Cooke was heavily involved in patenting work, and was a member of the committee whose advice led to the Patents Act 1919. Alfred Carpmael, was a prominent patent agent of his time, and the author of the first handbook on 'Patent Laws of the World.^[7]

Around the time of World War I, the firm acted in patent litigation regarding electric light bulbs. It related to an invention by the General Electric Company of the USA that involved using filament from tungsten.^[8]

In the 1930s, the firm was involved in drafting agreements for the laying of the first transatlantic telephone cable.^[9]

Mid-1900s

In the 1950s, to avoid a notoriously unpredictable English judge, the firm took the unusual move of bringing a patent case in Scotland, despite the lack of experience of patent litigation there. The move, for a textile machinery manufacturer, was successful,^[11] It was closely followed by another similar case on behalf of the Jockey Company of Chicago over its invention, Y-fronts, which were being manufactured under licence in Scotland.

Late 20th century

In the 1960s, Bristows was involved in a patent case on the jet engine, Renee Anxionnaz and Societe Rateau v Rolls-Royce, De Havillands and the Ministry of Aviation, .^[12] Sir Frank Whittle the inventor of the jet engine, was the expert for Bristows and the trial lasted about five weeks.

The continuing expansion of the firm in the 1970s, and the landlords' decision to redevelop 1 Copthall Buildings, led to a move to Lincoln's Inn Fields.

In 1997 the firm advises on a joint venture between BSkyB, British Telecom, HSBC and Matsushita (now Panasonic) to create Open, the world's first digital interactive television service on Sky.^[14]

In 1998, the firm shortened its name from Bristows Cooke & Carpmael to Bristows.

In 2002 Bristows represented Sony Computer Entertainment Europe (SCEE) in an action brought against "chipping" of PlayStation games consoles,^[15] and, following a six-year case against the Metropolitan Police, secured the image rights to Doctor Who's TARDIS for the BBC.^[16]

In 2003, the firm acted for Bayer AG on the £25 million financing aspects of its exclusive marketing agreement with GW Pharmaceuticals plc relating to the marketing of GW's pioneering cannabis-based medicine Sativex®.^[17] In the same year, the firm acted for VIA Technologies in a hard-fought competition law battle between leading chip producer Intel and its smaller competitor, VIA Technologies. In this case, the Court of Appeal decided that VIA Technologies can bring Intel to trial, and alleged that Intel's behaviour is anti-competitive, that the way Intel uses its huge patent portfolio seriously harms smaller rivals, and that Intel is driving rivals out of business and harming consumers.^[18]

The decision of the European Court of Justice (expected mid-2012) is keenly awaited by those in the industry and the legal sector.

In 2009, the firm acted for the defendants in the first UK case where compensation has been awarded to an employee inventor.^[23] In 2010, Bristows won TMT team of the year at The Lawyer Awards 2010 for its work on the Smith and Nephew litigation mentioned above, which colloquially became known as "The Rocket Docket" for its speed from commencement to judgment.^[24] The firm also won the UK Patent Contentious Award 2010 at the Managing Intellectual Property Global Awards.^[25]

Not only does this technology allow aircraft faults and aviation incidents to be investigated more quickly but also provides other benefits, such as improved scheduling for vital repairs and better aircraft route planning and fuel efficiency.^[27]

In 2011, the firm also achieved a groundbreaking win for IPCom in a telecoms patent action before the UK High Court. IPCom was sued by Nokia in April 2010 for revocation of a patent relating to a mechanism for controlling access to the random access channel, a channel used by mobile devices when accessing the mobile telephone network. IPCom countersued for infringement of the patent in June 2010 by each of Nokia's UMTS-enabled devices (UMTS is the mobile telephone standard under which the UK 3G network and UK 3G mobile devices operate). The Court upheld IPCom's patent as valid and infringed (subject to a minor amendment to the exact form of its claims).^[28]

In November 2013 the UK's Court of Appeal handed down a judgment in the case of IPCom v HTC that is significant for the enforcement of patents in the UK. Bristows acted for the successful claimant, IPCom GmbH & Co KG, and the case concerned whether national courts should proceed with a patent dispute where the validity of the same patent is also being considered at the European Patent Office ("EPO"). The Court of Appeal looked again at the guidelines which courts should use in exercising their discretion in such cases. Lord Justice Floyd concluded that, given the tensions inherent in the European patent system, judges should maintain their ability to exercise a discretion to progress or stay a case depending upon its facts. One factor in favour of a stay would be if the patentee were likely to irrevocably gain some compensation from the defendant which might later be found to have been wrongly bestowed. If the patentee is prepared to give an undertaking to return any such money, however, then allowing the proceedings to progress in parallel could achieve at least some certainty as between the parties in a sensible timescale.^[34]

In December 2013 the Patents Court handed down its judgment in Smith & Nephew v ConvTec No. 2.^[35] Bristows acted for the successful claimant, Smith & Nephew in the most recent instalment of litigation involving ConvaTec's patent for silverised wound dressings (silver being known for its healing properties).
