As regards litigation, we regularly advise leading French and international groups in their patent disputes, in various fields (pharmaceuticals and life sciences, telecommunications, mechanics, IT, chemistry).

Our experience covers the dispute regarding the counterfeit and the validity of patents, as well as disputes regarding patent licensing or co-ownership contracts.

We support our clients in multi-jurisdictional disputes, where we steer and coordinate the procedural strategy in several countries.

We advise our clients on all the legal aspects of their patents, whether to give a legal context to an innovative activity (work contracts, research and development contracts, confidentiality agreements), or to draft and negotiate the agreements necessary to the development of a patent or know-how (licensing, sale or co-ownership contracts).
