Representing European and non-European companies of all sizes before the EPO and the French Patent Office, our Paris office is tightly integrated with the practices of the firm’s other offices so as to ensure an efficient, coordinated global approach. Our Paris office legal staff includes qualified European and French patent attorneys, thus allowing us to communicate directly with clients about European and French patent law in the three official languages of the EPO. Our European practice is comprehensive, with a particular focus on European opposition and limitation proceedings, European and French litigation support and strategy, European and French national patent prosecution, patent drafting, prior art searches and patent watch services, IP due diligence, patent education seminars and counseling to assist in the implementation of in-house IP strategies.

With fluency in Japanese language and deep knowledge of local customs, we can easily move between the Western and Japanese ways of doing business and help our clients avoid the subtle pitfalls that make cross-cultural ventures difficult.
