James specialises in patent litigation. He is “technically very insightful” (Chambers 2024) and leaves “a very positive impact” on clients (JUVE 2024).

James’ doctorate in optoelectronics and general background in physics provides him with a firm understanding of highly technical issues. He is experienced in working with a diverse range of technical subject matter from mobile telecommunications, human computer interaction, and data storage to immunoassay techniques and pharmaceuticals. He has been at the cutting edge of standard essential patent and FRAND disputes for more than 20 years. His work in this field has spanned four generations of telecommunications technology: 2G, 3G, 4G and 5G, and has led to successful outcomes for both SEP holders and implementers.

James was closely involved with preparations for the UPC and led a team in our well publicised UPC Moot designed to stress test the UPC procedures in a real-time framework. He has recently been involved in co-ordinating proceedings across the US, UK, Germany and the UPC.
