Full AnalysisThe patent team of Allen & Overy’s French office continues to put pressure on the market leaders, both through its work for multiple high-profile pharmaceutical companies and via a growing client list in telecommunications. Its visibility on both ends of the patent litigation spectrum is undoubtedly helped by highly regarded partners Laëtitia Bénard and David Por, who steer the life sciences and telecommuncations teams respectively. Perhaps one of the most important cases for the firm has been the dispute over cancer drug fingolimod, where Béna...

Full AnalysisOne of the challengers to the market-leading patent litigation practices in France, the Paris litigation team at Hogan Lovells is small with just four litigators. This is especially true when compared with the two market leaders August Debouzy and Hoyng ROKH Monegier. The exceptional visibility of lead partner Stanislas Roux-Vaillard, however, makes up for this disadvantage. The young team in this international firm also benefits from a steady stream of high-end clients from the global patent practice’s excellent network

The v...
Full AnalysisFor its small size, this well-positioned team is active in an impressive amount of patent litigation for international clients in the French part of pan-European or even global proceedings.

Instead, de Gaulle Fleurance takes a broad approach and advises on all IP matters, often on the int...
