About

Provided by August Debouzy

Headed by well-recognized IP specialists, Grégoire Desrousseaux, François Pochart and Lionel Martin, August Debouzy’s IP team provides a complete range of legal services, including litigation, both at the national and European levels, and strategic advice aimed at valuing, protecting and transferring IP rights (licensing and freedom-to-operate opinions, patent prosecution before the EPO, IT contracts, transfers of know-how and technology and optimizing trademark portfolios). The IP team frequently leads the way to shaping first-of-a-kind solutions to complex intellectual property issues and disputes, and help their clients in finding creative solutions to reach out of court settlements that often allow them to avoid lengthy and costly litigation proceedings.

August Debouzy is one of the only firms in the French market that can provide in one and only team, such a high level of technical understanding and the capabilities to act in litigation. Over 50% of the IP team’s work includes patent litigation before courts in France (infringement, nullity actions, compensation for employees’ invention and appeals against the decisions of the French Patent Office), before the EPO (opposition) and the Unified Patent Court (UPC).

The IP lawyers regularly team up with the firm’s tax, corporate, employment and competition law teams (the latter notably on FRAND issues in the telecom area).
