Ranked in tier 1 in the Legal 500 category, “Trademarks, Designs and Copyright” and in WTR, Armengaud Guerlain is a top firm in Trademark law.
In litigation, our team ardently defends the interests of its clients, particularly in the context of infringement actions, applications for invalidity, or forfeiture of trademarks.

We also advise our clients, whenever possible, to reach an amicable solution resulting in a transactional settlement agreement.

Given the firm’s extensive knowledge of the practices of the trademark authorities, Armengaud Guerlain is actively sought by holders of prior rights to file oppositions before relevant authorities, to respond to them and to bring appeals against them.

The firm is also competent in bringing large-scale counterfeiting disputes before the criminal courts.

This activity is led by Stéphane Guerlain, who is “highly experienced and reliable in the field of trademarks”, and Catherine Mateu, an “excellent negotiator” who deploys a “good strategy in the field and before the courts” (source: Legal 500).
