Strategically protecting your intellectual property rights and preventing disputes is our main objective.

In the event that you face a conflict, our litigation team is there to defend you. We have extensive experience in defending clients’ rights in relation to their trademarks, patents, designs, copyrights and domain names, both in the physical world and online.


We act in French, EU and international courts, and work with a global network of like-minded referral firms with whom we have built strong relationships.
This means that our clients are supported by the same overall strategy and approach in any given jurisdiction.

Wherever possible we encourage out-of-court settlements, but when that is not possible, our team has the experience to structure effective strategies to achieve the best commercial result for our clients.

We are particularly active in disputes related to infringement, invalidity or forfeiture, unfair competition and cybersquatting.

Our approach is hands-on and personalized when assisting clients who face brand enforcement issues.

We take extra steps to ensure our recommendations are clear and straightforward, and streamline our processes to make everything as easy as possible for our clients.
