Andrew Bowler


Andy’s advice covers the full range of intellectual property rights, with a particular emphasis on patents, trade marks, registered designs and trade secrets.

Andy has considerable experience of representing high profile clients in IP disputes across a wide range of technologies, including complex mechanical and FMCG products, mobile phones, automotives, pharmaceuticals, electronics and medical devices. He has conducted several successful mediations of IP disputes and regularly provides freedom to operate and validity opinions.

Andy has recently assisted a leading consumer products company in successful trade mark proceedings before the CJEU. His patent litigation experience has included acting for Kennametal in successfully defending patent infringement proceedings brought in the Patents Court in London by their biggest competitor (Sandvik v Kennametal [2011] EWHC 3311 (Pat)).

He has also successfully represented Siemens and its customers in relation to patent infringement proceedings in the field of wind turbine technology both in the High Court (Wobben Properties GmbH v Siemens PLC & Ors [2015] EWHC 2114 (Pat)) and in the Court of Appeal (Wobben Properties GmbH v Siemens PLC & Ors [2017] EWCA Civ 5) – both tribunals held that the patent in issue was invalid and also not infringed by the Siemens technology. In early 2016, he secured a win for Samsung as part of the defence of patent litigation proceedings brought by Unwired Planet against Samsung and Huawei. In a decision from January 2016 ([2016] EWHC 94 (Pat)), the Court found that both Unwired Planet’s patents that were in issue were invalid and should be revoked.

Andy regularly provides comments to the national press (including most recently The Times and The Guardian) on intellectual property issues. He is on the Lexis Nexis IP & IT Editorial Board.

Some other recent cases include:

  • Heineken v Anheuser – Busch
  • Conversant v ZTE and Huawei (standard essential telecommunications patents, FRAND and jurisdiction challenge – leading case in the court of appeal on appropriate forum for SEP/FRAND disputes)
  • Jushi v OCV (first case in Court of Appeal relating to overlapping ranges)
  • Alcon Pharmaceuticals v Pharmathen (PI proceedings relating to travoprost)
  • Allergan v Ipsen (Swiss type claims and EPC 2000 claims regarding second medical uses of botulinum toxin)
