David has tremendous technical range with a background in mechanical engineering and physics. He has experience of writing and prosecuting patents on a wide range of topics, including: medical devices, photonic devices, x-ray diffraction, metamaterials, quantum technologies and machine learning.

Before joining the patent profession, David spent 10 years as a researcher in microsystems and semiconductor devices, working mainly on defence related projects funded by the UK and US governments (e.g. DARPA).




  • Ten years’ experience in defence related research and development prior to training as a patent attorney, named inventor on seven patent families
  • Handling patent work for Malvern Panalytical Limited, preparing and filing patent applications to protect new inventions and managing a portfolio of around 85 pending cases (at last count) throughout the world, regularly meeting inventors to discuss new inventors and how to make progress with patenting older ones
  • Extensive experience of working with University clients and University spinouts, for example in wireless power communication, medical devices, compressed imaging, and machine learning
  • Handling patent prosecution for Xtera Communications relating to subsea and terrestrial fibre optic communications technologies
  • Preparing and filing a patent application on all optical memory for Oxford University, against a challenging publication deadline in Nature Photonics. It was great to see the same drawings I had been working with late into the evenings pop-up on the front page of Reddit shortly afterwards on my train journey into work


“Dave is proactively requested by our inventors to work on protecting their ideas because he has demonstrated such a high level of ability over many years. The speed at which he grasps complex new ideas creates an enormous amount of trust that their inventions are in good hands during drafting, and his proposals during prosecution are insightful and show a thorough understanding across a huge breadth of technologies. He quickly establishes an easy rapport and he explains complicated concepts well to a range of audiences. Couldn’t recommend him enough.”

Rachel Grovenor, Licensing and Ventures Manager, Oxford University Innovation.

“Dave and Katie, can I take this opportunity to say how much I’ve enjoyed working with you both on this training project, and I can’t express my gratitude enough for all the hard work you’ve put into it, especially organising and delivering excellent talks on every occasion, you are both a real credit to BB as approachable, friendly and very knowledgeable attorneys.”
