Cousin & Associés – France 2021

JUVE Comment

This small IP boutique pursues a partner-centric approach with a strong position in the market, mainly in patent litigation. Most recently, however, it has built up a practice in ongoing advice, for instance on licensing agreements and inventors’ rights, especially in the biotechnology sector. The list of often long-standing clients includes companies from the auto, aviation and life sciences sectors, which the firm frequently advises in patent disputes. Among these are SMEs, as well as corporations like Thales. The firm litigated for the latter in a dispute against Lufthansa regarding aviation technology. Like similarly set-up competitor Szleper Henry, Cousin & Associés maintains close contacts with German companies. Recently, however, it has also acquired clients from other countries. The firm is currently representing Japanese tractor manufacturer Kubota in a dispute over patent filing against the INPI, and a US pharma company in a nullity suit. The team is also carving out a name for itself with work for pharma start-ups.

Strengths

Patent litigation for a broad spectrum of industries.

European strategy

The firm does not have a fixed network, only informal partnerships with various IP firms, mainly in Germany and the UK. By refraining from joining an institutionalised network, the firm remains flexible, but is constantly competing for sought-after cooperation partners.
