Gide Loyrette Nouel – France 2022

JUVE Comment

The patent litigation team of this national full-service firm is one of the challengers to the French market leaders in patent litigation. With its firmly established team of partners, the practice covers a wide spectrum of work in the French part of international patent cases. It has a pronounced strength in life sciences litigation. In this sector, such major players as BMS and Genentech trust in the team, which is also present in the ongoing important issues, such as SPCs, as well as in biotech suits. Gide Loyrette Nouel is, however, seen less often in high-profile telecommunications proceedings than competitors such as Allen & Overy.

The firm prepared for the departure of senior litigator Grégoire Triet a long time in advance. Along with the move of Arnaud Michel this creates space for up-and-coming lawyers in the team. A counsel appointment underscores the ambitions of the practice, led by the well-established Raphaëlle Dequiré-Portier, to grow sustainably.

The patent practice uses its interface with the antitrust practice to conduct joint proceedings before the European Commission. This competence sets it apart from national competitors like Loyer & Abello.

European set-up

Gide Loyrette Nouel has many years of experience litigating in the French part of international patent proceedings. For these cases, the team is trusted by numerous pharma companies and medical product manufacturers. The patent practice frequently works in cooperation with national IP boutiques, including Arnold Ruess in Germany, or national full-service firms, such as Gleiss Lutz. In suits before the UPC, the firm will have to compete with internationally-integrated firms to win over its clients with this experience. Although Gide has its own offices in London and Brussels, the firm does not advise on IP from these locations.
