David Sant

David has 29 years’ experience in IP. He is dual qualified as a Solicitor-Advocate and European patent attorney, with time in leading London IP practices and the European Patent Office.

A Physics graduate, David specialises in patents, especially disputes, litigation and arbitration, but also transactional, prosecution and licensing work. He worked for many years at the EPO, and, unusually for a UK lawyer, has experience on the EPO’s Opposition Division. A major component of David’s practice in recent years has been in standard essential patents (SEPs) and FRAND disputes, on the interface between IP and competition law, in relation to cellular technologies. He has acted for claimants and defendants before the UK High Court, in EPO proceedings, and before the ICC. David has published and presented widely on IP issues.

David spent several years at the respected IP practices Taylor Wessing and Bird & Bird. He was then partner in charge of European patent disputes at Pearl Cohen.

His practice covers all technical areas, but focuses on the physical sciences, notably in optics, sensors, communications and mobile telephony. David has acted for a wide range of clients, ranging from major international concerns in the telecommunications field to small businesses in the printing sector, and a firm in life sciences.

David has extensive knowledge of the Unified Patent Court and unitary patents: for several years he headed the EPO’s bureau in Brussels and worked on the legislative project COMPAT which later became the UPC/unitary patent.

Recently David conducted the defence in a major patent litigation before UK High Court relating to kits for separating blood components, and supported parallel disputes in Germany, France, USA and the EPO. David successfully enforced patents in sports equipment being infringed in UK and globally and successfully obtained revocation of two UK patents in the military sphere. He fronted many hostile meetings in various FRAND disputes for telecoms clients and was responsible for the technical aspects of very large FRAND dispute before the ICC.

In transactional matters, he has worked extensively on the licensing of the IP in proton beam machines for cancer treatment.
