James Channer


Sitting in the Engineering and Tech teams, James works in diverse fields of technology that encompass renewable energy, vacuum cleaners, and practical applications of quantum mechanics. He assists clients all the way from development of an initial concept through to opposition proceedings at the EPO and national litigation. James has developed particular expertise in drafting and prosecuting applications relating to medical systems such as drug delivery devices, surgical robots and advanced devices for in-vitro diagnosis of infectious diseases.

James also undertakes clearance work, providing commercially aware freedom-to-operate and validity advice to clients. He especially enjoys finding creative solutions to the thorniest of problems to help clients achieve their aims. James has also played a key role in a multinational litigation where his razor sharp analysis was highly valued by the team.

James joined Carpmaels & Ransford in 2016 having graduated from the University of Durham with a first-class Masters degree in Theoretical Physics and a string of awards for Outstanding Achievement. He studied chaos in systems of quantum vortices in his final year project and has undertaken research into Josephson Junctions in superconductors. His academic background helps James grasp the important details of clients’ inventions quickly and achieve robust protection for them.

Away from work, James can be found sailing on the Thames or running along its banks. He also plays the piano, but recommends that others remain out of earshot.
