CASALONGA is once again ranked by JUVE Patent among the top French patent law firms, both in patent litigation (“Litigation: Lawyers”) and prosecution (“Patent Filing”).
“Of all the firms in the French market, mixed practice Casalonga has undergone perhaps the most significant development over the past year, consistently driving forward its strategic transformation. The firm aims to join European market leaders in UPC litigation (...). To this end, Casalonga has recently integrated lateral hires in Munich, Düsseldorf and Milan and is fostering close inter-office collaboration across all offices. The firm’s culture has traditionally embraced close cooperation between lawyers and patent attorneys on equal footing”.
In addition, Marianne Gabriel is ranked among the leading lawyers in patent litigation, and bothshe and Arnaud Casalonga are individually recommended as attorneys-at-law. Ghislain de Trémiolles is recommended as a patent attorney with expertise in digital communication and computer technology.
