David entered the patent profession in 2003 and worked for Barker Brettell and then Beresford & Co before joining Potter Clarkson in 2008.  He was appointed as a partner in 2014.
One of David’s aims is to realistically set his client’s expectations of success so that they can make informed commercial decisions as to how best to protect their intellectual property, and also maximise the value of their IP budget.

David has extensive experience in drafting and prosecuting patent applications before numerous patent offices, engaging with patent examiners over the telephone and in person, managing patent portfolios, and representing his clients in hearings at the EPO.  David has also been involved in appeals from the UKIPO to the courts in relation to the patentability of computer implemented inventions.  These include, in 2007, a successful appeal to the English High Court for Astron Clinica et al, following which the UKIPO’s practice of not granting claims for computer programs was overturned.

Outside of work, David enjoys the fresh air that comes with open water swimming and watching rugby.
