Bronze - Firms: litigation

For almost three decades IP boutique Armengaud Guerlain has been a dominant presence on the Paris patent market, maintaining relationships with top clients that have lasted in excess of 27 years. It demonstrates a collaborative ethos that extends outside the firm, with its sturdy network of international allies always on hand to step in when issues get global. The pair of star litigators bringing the practice acclaim are Stéphane Guerlain and Catherine Mateu. Guerlain has been litigating since 1987 and for the past decade has been embroiled in an employee invention dispute on behalf of a telecommunications corporation; Mateu is especially strong on the international stage – thanks in part to her language facilities in Spanish and English. She has lately been acting for energy company TTK in an infringement case spanning France, the United States and Canada.
