Patent Attorney London
Profile of Harry Ventress

I joined the patent team at D Young & Co as a technical assistant in 2017. I have a strong technical background in the fields of physics, engineering and IT and enjoy applying this to all aspects of my role.

Since joining the firm I have gained experience in the prosecution of UK, European and foreign patent applications in a wide range of technologies for a variety of clients.

Prior to joining D Young & Co, I completed a masters degree in physics at the University of Bath. During my degree I completed a research project investigating the electrical dynamics of micro and nano-scale electrical discharges and characterised the transition from classical to quantum breakdown mechanisms as the nano-scale is approached.
