In litigation, we support, sometimes for over 30 years, some of the most well-known brands in the world in the luxury, fashion, foodstuffs, cosmetics and toy sectors.

Our experience and skills enable us to ensure, for our clients, the daily management of repetitive disputes (customs disputes, seizure of products, etc.), all the while acting on the most complex cases before national, civil, criminal or community jurisdictions.

As legal advisers, we are regularly consulted by our clients for developing their brands and negotiate and draft all the contracts necessary (licence, sale, coexistence, etc.), for which we have suitable perspective thanks to our experience as litigators.

Lastly, we manage a sizeable portfolio of French, European and international brands for our clients. Thanks to our considerable network of correspondents, we are also in a position to manage foreign trademarks filed throughout the world.

Our intellectual property rights management activity also covers legal advice in the strategy of filing trademarks.

We regularly act for our clients in disputes concerning designs and models, which are often combined with copyright issues.

We also offer advice, help draft contracts, and manage design and model portfolios.
