What Casalonga does
Casalonga is a privately held European intellectual property law firm headquartered in Paris, France, operating continuously since 1867. The firm offers prosecution, litigation, and advisory services across patents, trademarks, designs, copyrights, domain names, unfair competition, distribution law, and IP strategy, with a specialized Wine, Spirits & Terroirs department. Its service portfolio spans nine practice areas, anchored by core offerings in Patents, Trademarks, Design & Copyright, UPC Litigation, Litigation, IP Strategy & Contracts, Domain Names/Internet/Software, and Wine/Spirits/Terroirs, supported by IP tools and training. The firm employs over 120 attorneys-at-law, patent attorneys, trademark attorneys, and staff, and operates 11 offices across France (Paris, Grenoble, Toulouse, Montpellier, Beaune, Pau, Nantes), Germany (Munich, Düsseldorf), Italy (Milan), and Spain (Alicante). The Alicante location provides proximity to EUIPO, supporting streamlined trademark and design prosecution across the EU.
Revenue is generated entirely through professional service fees billed on a quote-based, multi-year contract structure, with pricing determined by matter complexity, technical field, jurisdictional scope, and length of engagement. The go-to-market is enterprise field sales: the firm serves large French and international companies across sectors including luxury goods (L'Oréal, Louis Vuitton), retail (Carrefour, Lidl), agriculture/chemicals (Syngenta), beverages and spirits (Campari France, Jägermeister, Champagne Beaumont des Crayères), and sports (Société du Tour de France). Distribution is direct through attorney-client relationships across the eleven offices, with no intermediary or reseller channels. Underlying technology consists of proprietary digital tools — Interactive UPC Code (case law reference), Unitary Patent App (fees comparator), IP Access (client portfolio management portal), and Domain Names Watch (monitoring) — which supplement traditional legal practice rather than serve as standalone products. Ownership remains within the Casalonga family and partner group, with no external private equity or venture capital involvement.
