Bronze - Firms: litigation

Armengaud Guerlain has been a fixture of the French patent market for more than 25 years and prides itself on a collaborative approach that prioritises optimal results and cost-effectiveness over the accumulation of fees. An extensive network of foreign associates makes the coordination of cross-border litigation a breeze, not just across Europe, but also in the United States and Asia; as one recent example, it has been defending WIKO against a series of patent infringement actions initiated by Philips in France, the Netherlands and Germany. Leading on this case is Catherine Mateu, who has also gone out to bat for pharmaceutical company Estar Medical and milk packaging innovator Novapet. Whether dispensing strategic advice, litigating or negotiating contracts, the versatile practitioner is cosmopolitan in outlook; fluent in French, English and Spanish, she also shares her knowledge by speaking at conferences and teaching law to students at the University of San Francisco. At her side is founder and IP veteran Stéphane Guerlain, who continues to keep busy for Telecom Design in an employee invention dispute that has been playing out for over a decade.
