Background
James joined Dehns in 2013 fresh from completing his PhD in Theoretical Physics at the University of Bristol. His research was focused on optics and catastrophe theory, and introduced to the field several new laser beam profiles with unusual propagation properties. Before that, he graduated with First Class Honors in a Physics MSci at the University of Bristol. James became an Associate of the firm in 2019, and a Senior Associate in 2023.
Type of clients and client work
James works with innovative companies of all sizes to identify and protect their inventions in a wide variety of high-tech industries throughout physics and engineering. Some interesting examples of work include: solid-state lasers, satellite sensors, unmanned aerial vehicles, 3D-printed prosthetics, laser-fabricated optical fibres, automotive technology, robotic warehousing, fire suppression systems, medical devices, and sports equipment. He particularly enjoys working closely with clients to understand the core concepts at the heart of their technology, as well as the commercial realities guiding their wider strategies, in order to build resilient, growth-oriented IP portfolios.
Expertise
James works in a wide array of technical fields throughout Physics and Engineering, and has experience in all aspects of patent prosecution. However, he has particular expertise in invention harvesting and portfolio development, working directly with inventors to create robust coverage of their technology, and advising on worldwide filing strategies to balance reach and impact with real-world commercial pressures. As a result, James has particular experience working with clients such as startups and scaleups looking to leverage their IP to maximum effect.
