NTT Global Data Centers Americas, Inc. (commonly "NTT GDCA"; formerly RagingWire Data Centers, Inc.) is the Americas data-center operating unit of Japan's NTT Group. It is headquartered at 1625 W. National Dr., Sacramento, California, and is a wholly owned subsidiary of NTT (Nippon Telegraph and Telephone Corporation, TYO: 9432); its direct parent is NTT America, Inc. The business traces to RagingWire, founded in 2000; NTT Communications bought an 80% stake in 2014 and the remainder by 2018, and the RagingWire brand was folded into NTT Global Data Centers in 2019–2020. Glassdoor lists 501–1,000 employees and $100–500M revenue for the unit (self-reported, not audited); NTT's global GDC business reports roughly 3,500 employees and 150+ facilities across ~20 countries.
Operations. The company designs, builds, and operates mission-critical colocation and wholesale data centers, offering build-to-suit wholesale capacity, private vaults, dedicated cages, and multi-rack deployments, plus flexible power configurations, carrier-neutral connectivity, and cooling infrastructure. U.S. campuses are in Ashburn (VA), Chicago/Itasca (IL), Dallas (TX), Hillsboro (OR), Phoenix (AZ), Sacramento (CA), and Silicon Valley (CA). It is an operating company, not a patent licensor.
Litigation posture. The tracked data shows one case, with the company as defendant only (0 as plaintiff) — the profile of an operating company being targeted rather than a patent assertor. The sole suit is Valtrus Innovations Ltd. et al. v. NTT Global Data Centers Americas, Inc., filed April 9, 2026 in the Northern District of Illinois (1:26-cv-03945) and transferred to the Eastern District of Texas (2:26-cv-00679, Judge Rodney Gilstrap) under MDL No. 3190.
Context. The plaintiffs, Valtrus Innovations and Key Patent Innovations, are licensing entities asserting patents acquired from Hewlett-Packard Enterprise covering data-center cooling, temperature control, and atmospheric monitoring (e.g., U.S. Patents 6,854,287, 6,868,682, 6,718,277). NTT GDCA filed an answer and counterclaims before the MDL transfer. The suit is part of a broader campaign against data-center operators — including Lumen, Equinix, Iron Mountain, and Digital Realty peers — and their equipment suppliers, which prompted Vertiv's declaratory-judgment action and the MDL consolidation.
