About

Provided by CASALONGA

Founded more than 150 years ago, CASALONGA is a leading European IP law firm of more than 120 lawyers, patent and trademark attorneys, attorneys-at-law and engineers with offices in France (including Paris, Grenoble, Toulouse, Montpellier, Beaune, Pau, Nantes), Spain (Alicante) and Germany (Munich), as well as a global network of correspondents.


CASALONGA offers its clients full IP services, from prosecution and counselling to litigation, covering all types of IP rights (trademarks, patents, designs, domain names, copyright, etc.) and related laws (unfair competition, distribution, economic rights, etc.).


The firm's attorneys have extensive experience in proceedings before the patent and trademark offices and regularly appear before the courts.


As such, CASALONGA was the first law firm to include both attorneys-at-law & patent and trademark attorneys in France, creating a full-service IP firm whose clients do not have to engage different firms for prosecution and litigation. The combination of attorneys-at-law and patent and trademark attorneys enables CASALONGA’s teams to follow their client’s cases from the inception phase through any court proceedings and also provides more balanced advice, taking into consideration litigations risks.
