Associate, Patent Attorney London
Profile of William Smith

I joined D Young & Co in 2019 and enjoy working with clients to build strong, commercially focused patent portfolios.

My practice covers a broad range of electrical and mechanical technologies, with a particular interest in computer-implemented inventions including machine learning, automotive and aerospace systems, electronics, and medical devices.

I am experienced in drafting and prosecuting UK, European and foreign patent applications for a diverse client base, including multinational corporations, SMEs and academic institutions. I also represent clients in oral proceedings in ex parte and opposition proceedings, including before the Boards of Appeal of the European Patent Office.

Before joining D Young & Co, I completed a Master’s degree in Physics with Particle Physics at the University of Southampton, where I was awarded prizes for best overall performance and best master’s project. I spent my master’s year in a research group at the Large Hadron Collider at CERN in Geneva, contributing to cutting-edge work in physics, engineering and computing.
