After finishing a mathematics degree at Pembroke College, Oxford, Ben spent seven years as a senior subeditor and contributor at New Scientist magazine. His wide experience of all areas of science, from the quantum to the cosmological, provided a great springboard for a move to the IP Bar.

Ben practises in all fields of intellectual property. His mathematical background is particularly applicable to highly technical subject matter such as electronics and telecoms patents. He has appeared in the Court of Appeal and CJEU, and regularly represents clients in the High Court, including the Intellectual Property Enterprise Court, as well as at the UKIPO at first instance and on appeals.

Benjamin is regarded in Who’s Who Legal 2015.


Ben’s legal experience includes major patent litigation, as well as actions in trade marks, passing off, copyright, design right, domain names, confidential information and comparative advertising. He has appeared as a junior in the Court of Appeal for HTC in HTC v Gemalto and for Huawei in Unwired Planet v Huawei & ors, and has acted as a junior in many High Court patent trials, most recently in PulseOn v Garmin as junior counsel for Garmin. He has appeared at the General Court in Luxembourg, and has conducted various trials on his own in the Intellectual Property Enterprise Court (formerly the Patents County Court).

As part of his early work, Ben spent seven months on secondment to a major firm of patent litigation solicitors. This has given him invaluable knowledge and insight into the litigation process, including case strategy and the instruction and handling of expert witnesses.

Ben is co-author of A User’s Guide to Trade Marks & Passing Off  (along with Hogarth’s Nicholas Caddick QC). His other publication credits include co-editing the intellectual property chapter of Clerk & Lindsell on Torts, co-editing Copinger & Skone James on Copyright, and extensive research on Moral Rights.

In 2012 Ben was the UK’s National Rapporteur to the International League of Competition Law (LIDC).
