Nathalie is one of the founding partners of P3B AVOCATS, in which she strives to provide an excellent tailor-made legal service, in close cooperation with her clients.

For the past twenty years, Nathalie has been advising and assisting her clients in technology, digital and immaterial law. She has also been handling intellectual property issues applied to IT matters, both as consultant and as litigator.

Her clients are major operators in IT fields (telecom operators, MVNOs, integrators, software companies, service providers, etc.), as well as other private or public-sector companies or agencies whose activities heavily rely on technologies or are strictly regulated (agribusiness, environment, artworks, cybersecurity, e-commerce, etc.).

Her specific strengths

Nathalie is accustomed to working closely with legal departments, but also directly with IT specialists, engineers and researchers, in order to respond as effectively as possible to the operational constraints inherent to technological innovations (speed, adaptation, evolution of “classic” legal models).

She is always personally involved in all aspects of the projects submitted to her by her clients, in order to understand all the ins and outs of them.

Her motto

Constant adaptation to new and complex legal needs resulting from technological innovation, as well as the ability to combine “technical” and “legal” tools for quality and adequate results.
