Amadeus Global Travel Distribution, S.A. is the historic legal name of the Madrid-based travel-technology group now operating as Amadeus IT Group, S.A. (formerly Amadeus IT Holding, S.A.), commonly shortened to Amadeus. Founded in 1987 by Air France, Iberia, Lufthansa and SAS, it was listed on the Madrid, Paris and Frankfurt exchanges, taken private in 2005 in a €4.34bn buyout by Cinven and BC Partners (through WAM Acquisition, S.A.), and re-listed in Madrid in April 2010 (BME: AMS; IBEX 35; ADR: AMADY). It is a public company with roughly 20,400–21,600 employees, FY2024 revenue of about €6.1bn, and a market capitalisation in the low-to-mid €20bn range.
Amadeus supplies transaction processing and IT to the global travel industry, not consumer travel services. Its core asset is the world's largest Global Distribution System (GDS), a real-time platform for search, pricing, booking and ticketing used by travel agencies and travel sellers. Reported segments are Air Distribution; Air IT Solutions (the Altéa passenger service system covering reservations, inventory and departure control for airlines); and Hospitality & Other Solutions (hotel IT, airport IT, rail and payments). Operations run from Madrid (corporate), Sophia Antipolis/Nice (R&D) and Erding, Germany (data centre).
Litigation posture: operating company defending. The tracked data show 1 case, 0 as plaintiff and 1 as defendant, the classic profile of a large operating business targeted by a patent holder rather than an asserter itself. The single tracked suit is InternetAd Systems, LLC v. Opodo Limited et al., filed in the U.S. District Court for the Northern District of Texas, Dallas Division — not a plaintiff-friendly Eastern District of Texas venue.
Notable context: InternetAd Systems is identified in the record as a subsidiary of Acacia Research Corporation and an entity formed to license and enforce patents without practising them; it asserted U.S. patents (5,572,648; 5,737,619; 6,185,586; 6,456,025) originally issued to David Judson, covering website advertising technology. The published decision, InternetAd Systems, LLC v. Opodo Ltd., 481 F. Supp. 2d 596 (N.D. Tex. 2007), addresses standing and whether the licence transferred all substantial rights. Amadeus's connection to the case reflects its then-subsidiary online travel agency Opodo, which it later sold.
