David Sant is a Partner and Chair of the European Patent Litigation Group at Pearl Cohen’s London office. David has over 25 years of experience in patents and is a Solicitor-Advocate in England & Wales, as well as a European Patent Attorney. David’s practice covers UK and international patent litigation and arbitration, oppositions and patent prosecution, in all areas of the physical sciences.

David was previously at the EPO in Munich working on both examination and opposition proceedings, and specializing in position determination, optics, interferometry, and the measurement of non-electrical variables. He then moved to the EPO’s legal section, where he led an EU/EPO project of technical cooperation with the states of Eastern Europe preparing for accession to the European Patent Convention. David subsequently formed and headed the EPO’s bureau in Brussels, working with the EU institutions mainly on patent legislative proposals, including the proposed directive on computer-implemented inventions, the proposed Community Patent regulation (which led to the Unified Patent Court and the unitary patent) and European Patent Litigation Agreement. Since his work in Brussels he has written and presented extensively on developments on the forthcoming UPC and the unitary patent.

In recent years he has acted for clients in a number of high profile cross-jurisdictional patent litigation and arbitration cases, as well as EPO proceedings, especially in the electrical and telecommunication areas, including standard essential patents (SEPs). David is a member of the EQE committee (admitting new European Patent Attorneys to the profession) at the EPO. He is a member of the UK branch of AIPPI.
