I assist French and international clients in the management and defence of all their intellectual property rights (management of patent, trademark, design and domain name portfolios; intellectual property and contractual due diligence; drafting and negotiation of licensing and sale agreements; R&D; specialised litigation relating to infringement proceedings, oppositions, domain names, customs control, etc.), both in France and worldwide, thanks to a network of correspondents in each country.
 
I also have a strong focus on contentious work involving all intellectual property rights, which enables me to represent my clients before national and European courts, both in the framework of urgent protective proceedings and of full trials.
 
I act for a wide range of clients from various business sectors including the luxury, media, new technology, healthcare and wine industries.
 
I graduated from the Universities of Bordeaux (DESS in Wine Law) and Paris I (DESS in Industrial Property Law) and I am a lecturer in the Master 2 "Design Law" at the University of Lyon 2.
 
Before joining Fieldfisher in 2013, I was a partner at the US law firm Winston & Strawn (2007 to 2013), and at DS Avocats (2004 to 2007), after an 11-year experience at Ernst & Young Legal (1993 to 2004). Between 1988 and 1993, I was a trade mark attorney at IP boutique Cabinet Vittoz. I became a lawyer in 2003 and was admitted to the Paris and Nanterre bars. I am a registered agent at the European Union Intellectual Property Office (EUIPO).
 
I advise my clients in French and English.
