Stuart Arnott


A highly experienced patent attorney, Stuart drafts and prosecutes UK, European and foreign patent applications on behalf of clients, mostly in the engineering sector.  He has conducted oppositions and appeals at the European Patent Office, infringement and validity opinions, Freedom-to-Operate analyses, and patent revocation actions.

Stuart enjoys working with a variety of clients, from private inventors to multinational corporations and everything in-between.  Many are UK-based, while others are located in mainland Europe, Asia and North America.

Also a seasoned professional engineer, Stuart has particular technical expertise in aerospace technologies including: spacecraft propulsion systems; gas turbine engines; conceptual design of spacecraft and air vehicles (including UAVs and airships); flight simulation (including mechanical systems, engines, autopilots and flight dynamics); and aviation safety and accident investigation.  Although no longer flying, he remains the holder of a private pilot’s licence.

Stuart has worked in a corporate IP department as well as in private practice.  His in-house patent experience, combined with his engineering background, means he is well accustomed to liaising with both inventors and managers, across business functions and at all levels of seniority.

Outside of the office, Stuart is a keen equestrian and can usually be found on a horse somewhere in the countryside.

Stuart specialises in engineering subject matter, including:

  • Aerospace engineering
  • Printing technologies
  • Medical devices
  • Metal-making technologies
  • Automotive engineering
  • Oil & gas technologies
  • Scientific apparatus
  • Vaping devices

He also holds the postgraduate Certificate in Intellectual Property Law from Queen Mary College, University of London, as well as the Intellectual Property Litigation Certificate.

Stuart joined GJE in 2014, having trained at another top-tier London firm of patent and trade mark attorneys and worked in-house in the IP department at Rolls-Royce.

He entered the patent profession after a successful engineering career in the commercial and defence aerospace industries.

Stuart held senior engineering positions at Astrium/Airbus and DERA/QinetiQ, where he undertook challenging projects for prestigious client organisations including the UK Ministry of Defence, the US Defense Advanced Research Projects Agency, the European Space Agency, Rolls-Royce, Airbus and Boeing.

During his years in industry, Stuart gained particular technical capability in satellite propulsion.  Having worked initially on projects for some of the world’s leading operators of telecommunications satellites, he later became the lead industrial engineer responsible for the propulsion systems of the European Space Agency’s Mars Express and Venus Express spacecraft.
