Career
Lionel Martin is a partner within August Debouzy’s Patents team. He started working with August Debouzy in 2014 as an Industrial Property and Patent Attorney, following five years of experience at a renowned French industrial property and patent firm. His partnership with August Debouzy continued when he was admitted to the Paris Bar in 2016.
With a dual scientific and legal background and qualified as both a European Patent Attorney (EPA) and a lawyer, he handles patent litigation matters before the French courts, the UPC and the EPO (in French and English). He represents clients in opposition proceedings before the EPO and in the filing and prosecution of patent applications.
The vast majority of his cases are mixed patent litigation cases pending before both the EPO and the French courts or the UPC, with a high degree of interaction. His scientific training has led him to deal with cases in the fields of telecommunications (FRAND licensing induced litigation), energy, medical devices and automobiles, almost systematically involving large corporations, which has led him to deal with foreign clients.
Lionel also passes on his expertise to the next generation by providing academic training to top engineering schools (Ponts Paristech; CentraleSupélec, University of Michigan) and law schools (Paris-Saclay University: Master 2 LEAD; Strasbourg University: CEIPI).
