Nathalie Dreyfus

Nathalie Dreyfus is the founding partner of Dreyfus & associés in Paris. A French and European Trademark Attorney, she advises clients on trade marks, designs, copyright, domain names, online brand protection, wine and spirits, geographical indications and plant variety rights.

Her practice sits at the crossroads of advice and adjudication. She is a court-appointed expert before the French Cour de cassation (trade marks) and the Paris Court of Appeal (trade marks, designs and models), and an accredited expert with the WIPO Arbitration and Mediation Center and the Forum (US), as well as other international domain name dispute resolution centers. She also teaches at the École nationale de la magistrature (ENM), training French judges on IP matters.

Nathalie advises French and international companies, from start-ups to global groups in the luxury, fashion, wine and spirits and technology sectors, on brand creation, clearance and global filing strategies, and on the defence of their rights through oppositions, cancellation actions, anti-counterfeiting and unfair competition claims. She is known for her expertise in online enforcement, including cybersquatting, phishing, domain name recovery and platform takedowns, and for her work on IP issues raised by Web 3.0, NFTs and artificial intelligence.

In her expert capacity, she carries out certified IP valuations and strategic IP audits, helping clients measure and leverage the value of their intangible assets in transactions, licensing and litigation.

Nathalie is the author of several books and a regular contributor to IP/IT journals. She speaks frequently at international conferences, including INTA, AIPPI and IBA events, and spoke at the NDD Camp Paris 2026 round table on cybersquatting. She is an active member of INTA, ECTA, MARQUES, APRAM and AIPPI.
