Our services in France cover the complete range of intellectual property. That means we advise, manage copyrights and industrial property rights, undertake the conduct of legal proceedings, and draw up contracts.

At the international level, and particularly in Germany, our focus is on the management of IP rights. When drawing up contracts and conducting legal proceedings, we work together with a network of specialists.

Our clients in this field include a very varied range of businesses: financial and management companies, the food industry, personal services, drones, NGOs, connected objects (IoT), tourism companies, new energies, foundations, fashion designers.

We assist clients in selection and clearance of marks, file and prosecute trademark applications before the French Trademark Office (INPI), at international level at the WIPO (World Intellectual Property Office) in Geneva and the European Union Intellectual Property Office (EUIPO) in Alicante for trademarks and registered designs and manage elsewhere such applications and procedures through our local foreign registered attorneys network.

We manage worldwide trademark portfolios for clients and develop and implement watching programs.

We advise on questions involving law of contract, particularly licenses, coexistence agreements.

We conduct opposition proceedings and rights-infringement cases, and apply for declarations of invalidity or nullity of trademarks in proceedings in France, before EUIPO up to the European Court.
