Andy has specialised in contentious intellectual property matters, including related advisory work since qualification in 1999. His 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 cases in the UK High Court, the IP Enterprise Court and the Court of Appeal. He has also been responsible for opposition and cancellation proceedings in the UK IP Office, EPO and OHIM. Andy is regularly involved in the co-ordination of proceedings with parallel actions elsewhere in the EU and US and also has experience of litigation in China. He has conducted several successful mediations of IP disputes.

Andy advises clients across a wide range of technologies, including complex mechanical and FMCG products, mobile phones, pharmaceuticals, electronics and medical devices as well as music, films and other media. 

Andy has recently assisted a leading consumer products company in successful trade mark proceedings before the CJEU. His recent patent litigation experience has included acting for Kennametal, a $2 billion per year NYSE company, 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 ongoing 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.
