Plasseraud IP is a leading agency in France for IP protection and portfolio management. The firm has expertise in major technical fields including electronics, life sciences and mechanics. In November 2018, the firm announced its merger with IP firm Ernest Gutmann Yves Plasseraud, which further cemented its position in the market. Managing partner and IP star Cyra Nargolwalla is the key patent contact at the firm. Other prominent European patent attorneys are Nadine Rocaboy, who heads the start-up department, Eric Gruson, Ina Schreiber and Patent Star Bertrand Loisel.

The firm has built up its litigation practice, Plasseraud Avocats, with experienced IP lawyers such as Jean-Christophe Guerrini and Sandrine Bouvier-Ravon. In 2024, the law firm expanded its business through the integration of IP firm Bleger-Rhein-Poupon, and in 2025 it merged with Candé Blanchard Ducamp.
