Denis’ practical experience as a legal professional (in an agribusiness group and in several law firms specializing in intellectual property and brand naming) has enabled him to address the intellectual property issues of diverse business lines (food, wine and spirits, mass distribution, publishing, consumer electronics, audio-visual production, textiles, jewelry, musical instruments, pharmaceuticals, credit insurance, real estate development, energy, chemistry, weapons manufacture, design, etc.).

He deals with matters involving trademarks, domain names (particularly alternative dispute resolution procedures such as UDRP), industrial design rights, copyrights, designations of origin and geographical names, software/databases, and agreements (cooperation, consortium, and non-disclosure agreements, etc.).

Denis has been closely involved in launching many major brands (Safran, Arkema, Gemalto, EDF Bleu Ciel, Tereos, Nexter, Calderys, Belambra, Thelem Assurances, Provalys, Adoma, Prisme, etc.). He helped develop search and filing strategies and conducted international availability studies for these companies.

He is a member of the International Trademark Association (INTA) and the Association of Trademark and Design Law Practitioners (APRAM).

He works with CCI Essonne and several other organizations, including the French Institute of Chartered Accountants and EGENI Europe (the European Global Event on Domain Names).

In June 2000, he served on the Université Paris II’s DESS industrial property jury, wrote the chapter “Political Brands and Industrial Property” for the book Politicians are Brands Too (Editions du Moment, 2008), and collaborated on the work Trademarks, Users’ Guide (Editions Dunod, September 2013).
