Selex ES Inc.

Selex ES Inc. is the U.S. subsidiary of Leonardo S.p.A. (Borsa Italiana: LDO), the Italian aerospace, defence and security group. It is headquartered at 11300 W. 89th Street, Overland Park, Kansas, and its Overland Park operation has supported air-traffic navigation and surveillance equipment since 1991 (Leonardo press releases; GSA eLibrary listing). It is wholly owned by Leonardo and is not publicly traded. Employee and revenue figures are not reliably disclosed; one third-party estimate (Growjo) puts headcount near 480 and another source reports turnover around €40M, but I could not confirm either from company filings, so treat both as unverified.

Operations. The company designs, produces, installs and supports ground-based radio navigation aids — Instrument Landing Systems (CAT I–III), VOR, DME and TACAN — and next-generation surveillance systems including primary/secondary radars, multilateration (MLAT) and ADS-B ground stations. It also markets AeroBOSS airport surface-management and runway-incursion warning software, and describes law-enforcement and communications offerings on its corporate pages. Customers include the FAA, state aviation authorities, the U.S. military and international air navigation service providers. In November 2022 Leonardo agreed to sell Selex ES Inc.'s stand-alone Air Traffic Management business to Indra Air Traffic, Inc. (Indra Sistemas); closing was expected in Q1 2023.

Litigation posture. Selex ES Inc. is a defendant-only litigant in the tracked data — 0 plaintiff cases versus 2 defendant cases — consistent with an operating company being targeted rather than an enforcer. Both tracked suits were brought by Cedar Lane Technologies Inc., a Canadian entity founded in 2019 that Unified Patents, RPX and Stanford's NPE Litigation Database characterize as a non-practicing entity. Cedar Lane asserts patents acquired largely from Intellectual Ventures and has filed hundreds of suits, predominantly in the Western District of Texas and District of Delaware.

Tracked cases. Cedar Lane Technologies Inc. v. Selex ES Inc. (D. Del., No. 1:23-cv-00613) and Cedar Lane Technologies Inc. v. Selex ES S.p.A. et al. (D. Del., filed 2023-06-04) name both the U.S. subsidiary and the Italian parent. Public NPE-database records link the Selex ES suit to U.S. Patent 6,972,790 ("Host interface for imaging arrays"), an imaging/AV-related patent also asserted against camera and robotics vendors — reflecting Cedar Lane's pattern of suit clusters rather than any Selex-specific technology dispute.
