Sprint Communications Co. L.P.

Sprint Communications Company L.P. (commonly "Sprint Communications") is a Delaware limited partnership with its principal office at 6200 Sprint Parkway, Overland Park, Kansas. It is an indirect, wholly owned subsidiary of T-Mobile US, Inc. (NASDAQ: TMUS), a status it has held since Sprint Corporation's April 1, 2020 merger into T-Mobile closed. Before the merger it was an indirect subsidiary of Sprint Corporation (NYSE: S), then roughly 84% owned by SoftBank Group Corp. The legal entity tracks its lineage to Sprint's wireline business, whose corporate origins date to the Brown Telephone Company in 1899; a specific formation date for the L.P. itself is not verified in the sources reviewed. No standalone headcount or revenue is published for this entity — it files as a subsidiary. For scale, Sprint Corporation reported about $33.6 billion of 2019 revenue with roughly 28,500 employees; the Sprint brand was retired in 2020 and customer migration completed in 2023.

Operations. Sprint Communications is a regulated wireline carrier rather than the wireless brand. State and FCC filings describe it as an interexchange carrier (IXC) and competitive local exchange carrier (CLEC) providing long-distance, local exchange, private line and data services to enterprise and wholesale customers, plus international Section 214 global/limited global resale authority and a Tier 1 IP backbone (SprintLink). It also served as the telephone relay service (TRS) provider in New York. Filings state it has been winding down TDM services and migrating customers to IP.

Litigation posture. The tracked data shows 0 cases as plaintiff and 1 as defendant — the classic profile of an operating carrier defending, not asserting. Its sole tracked appearance is Sol IP, LLC v. Sprint Communications Co. L.P. et al., filed 2018-12-03 in the Eastern District of Texas, Marshall Division (No. 2:18-cv-00527), a plaintiff-friendly venue.

Context. Sol IP, LLC is characterized as an NPE by Unified Patents, asserting acquired patents originating with the Electronics and Telecommunications Research Institute (ETRI) covering MIMO/WLAN wireless transmission. That case was consolidated for pretrial purposes into Sol IP v. AT&T Mobility (2:18-cv-00526) alongside Verizon and Sprint entities, with Ericsson and Nokia intervening. Separately, Sprint historically asserted its own VoIP/voice-over-packet patents against other carriers (e.g., Sprint v. Time Warner Cable); that litigation is not part of the tracked case list above.
