James works with innovative companies of all sizes to identify and protect their IP in a wide variety of high-tech industries throughout physics and engineering. Some interesting examples of work include: Formula 1 technology, solid-state lasers, satellite sensors, unmanned aerial vehicles, 3D-printed prosthetics, laser-fabricated optical fibres, 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.
James heads the firm’s Automotive group, and has particular experience with robotics and automation of vehicles, as well as electrification and fleet management. He has a special interest 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 a long history of working with multi-national clients using efficient, high-volume filing strategies, as well as startups and scaleups looking to leverage their IP to maximum effect.
