Company overview. Alcatel-Lucent USA, Inc. — renamed Nokia of America Corporation effective January 1, 2018 — is the principal U.S. operating and sales subsidiary of Finland's Nokia Corporation (HEL/NYSE: NOK). Its lineage runs from Lucent Technologies Inc. (spun off from AT&T, 1996) to Alcatel-Lucent USA Inc. after the 2006 Alcatel–Lucent merger, then to Nokia, which completed its €15.6bn acquisition of Alcatel-Lucent in January 2016 (Wikipedia/Alcatel-Lucent; Nokia annual report). It is a wholly owned indirect subsidiary of Nokia Corporation through Nokia Solutions and Networks Oy and Nokia Solutions and Networks B.V. (court corporate disclosure statements). Registration lists Murray Hill, NJ (600 Mountain Ave, the former Bell Labs site); Nokia also consolidated a North American headquarters in the Dallas area (City of Dallas council documents). Nokia does not disclose standalone revenue or headcount for this entity, so only group-level figures apply.
Operations. An operating company, not an NPE. It sells and services telecom network infrastructure in the U.S.: 5G/4G radio access networks (AirScale base stations, massive MIMO), IP and optical transport/routing, fixed and broadband access, core/cloud network software, and related professional and integration services to operators, enterprises and governments (Craft.co; Nokia Form 20-F). It is a registered federal contractor (NAICS 517810, CAGE 064L4, roughly $176M in cumulative reported obligations) and holds U.S. patents linked to Nokia Bell Labs research.
Litigation posture. Purely defensive in the tracked data: 0 cases as plaintiff, 1 as defendant. That asymmetry is the signature of an operating company being attacked by an asserting party rather than of an NPE. Nokia of America has separately appeared as a PTAB IPR petitioner against patent owners such as Oyster Optics, but the structured record here captures only a single district court suit in the District of Colorado (Denver) — not a plaintiff-friendly Eastern District of Texas venue.
Notable case. Fiber, LLC v. Alcatel-Lucent USA, Inc., No. 1:15-cv-02135 (D. Colo., filed Sept. 25, 2015), consolidated with Fiber, LLC v. Ciena Corp. (13-cv-00840) and Fiber, LLC v. Viavi Solutions (15-cv-01743). Fiber, LLC — a Wyoming LLC with a Denver office asserting patents as "exclusive assignee" — alleged that ROADM and wavelength-selective-switch products infringed U.S. 6,430,332 and 7,095,917 ("Optical Switching Apparatus"). Finisar intervened. After claim construction, the parties stipulated to invalidity and non-infringement; the court entered final judgment for the defendants on Sept. 13, 2018, affirmed by the Federal Circuit (Fiber, LLC v. Ciena Corp., No. 19-1005). Fiber sued several optical-networking vendors in the same campaign — a pattern typical of patent-assertion entities.
