Feted as the 'most talented lawyer of his generation in France'

Managing Intellectual Property 2015

Stanislas brings insight to clients willing to take advantage of Unified Patent Court and French patent law. 

As the partner leading the IP team in the Hogan Lovells Paris office, Stanislas is an experienced patent litigator mainly involved in UPC, national and multi-jurisdictional patent litigations, mediations and arbitrations, representing international clients, notably in the field of life sciences and telecommunications.

A Representative before the UPC and admitted to the Paris Bar, he represents clients by advocating before before the UPC (notably at the Local Division Paris and the Central Division Paris) and IP French courts.

With a network of talented patent litigators worldwide, Stan also takes part in the conception and execution of the multijurisdictional strategies of clients, along the specifics of their industry and business model. He is involved in a number of pharma and biotech cases helping clients make the most of their patent exclusivity. He and his team collected the highest award for patent infringement in France and in Europe. He represents clients in the telecom industry in contractual FRAND defences to standard essential patents and in non-essential patent claims brought by non-practicing entities.

In specific chemistry and mechanical engineering cases, his ability to use evidence gathering tools such as the 'saisie-contrefaçon' helped clients gain leverage for early settlement of infringement situations. Stan is also involved in patent portfolio and know-how review and licensing, notably in corporate deals where IP valuation is key.

Stan is the author of the 'France' chapter of The Intellectual Property Law Review (Lexology In-Depth) .
