Patent Attorney London
Profile of William Smith

I have a strong technical background in physics and a keen interest in business, both of which I enjoy applying in my role.

Before joining D Young & Co, I completed a Master’s degree in Physics and Particle Physics at the University of Southampton, where I was awarded the School of Physics and Astronomy prizes for best overall performance and best master’s project. My final year was spent working in a research group at the Large Hadron Collider at CERN in Geneva, Switzerland, which gave me exposure to cutting-edge physics, engineering and computing techniques. My time at CERN was focussed on improving the performance of energy reconstruction in the CMS Electromagnetic Calorimeter for LHC Run 3.

I have experience in patent drafting and the prosecution of UK, European and foreign patent applications for a variety of clients, including multinational corporations, SMEs and academic institutions. My work covers a broad range of electrical and mechanical technologies but I particularly enjoy the challenge of computer-implemented inventions and excluded subject-matter areas.
