JUVE Patent

de Gaulle Fleurance & Associés – France 2021

JUVE Comment

The well-positioned IP team of this full-service firm is characterised by a broad set-up and frequently conducts patent litigation for companies from such varied industries as medical engineering, construction and automotive. The firm litigated for Maec, a subsidiary of Cahors Group, as co-defendant in the dispute between Quadlogic and Enedis over smart meter technology.

International companies such as Tyron Runflat, a UK supplier of flat tyre protection, have also put their trust in Francine Le Péchon-Joubert’s team for patent disputes before the French courts. But the De Gaulle Fleurance team does not have the international pull of similarly-positioned IP practices from national full-service firms such as Duclos Thorne Mollet-Viéville or Gide. In addition to patent litigation, all-round IP advice accounts for much work, frequently on the interface with commercial, corporate and IT. This expertise is mostly drawn on by French SMEs from the life sciences sector, for instance in licensing negotiations, matters of employee invention law or joint ventures with larger US pharma and biotech companies.

European strategy

The independent national firm has an informal network with various firms, some of which are highly-renowned in patents. In Europe, this is mainly in the key patent locations of Germany, Italy, the UK and the Netherlands, and overseas in the USA and South Korea. De Gaulle Fleurance has a small Brussels office, which mainly advises on corporate and unfair competition/antitrust, but does not have its own IP team. The firm therefore works with specialised IP firms in Belgium for cross-border patent issues.
