Adtran Inc

ADTRAN Holdings, Inc. (Nasdaq: ADTN; also listed in Frankfurt/Vienna as QH9) is a publicly traded networking and communications equipment company founded in 1985 and headquartered at 901 Explorer Boulevard, Huntsville, Alabama. It reports roughly 3,300 employees and trailing-twelve-month revenue in the ~$1.1 billion band. The "Adtran Inc" name in the case data is the U.S. operating subsidiary of ADTRAN Holdings, which became the group parent after the 2022 combination with Germany's ADVA Optical Networking.

Products and operations. Adtran supplies broadband access and transport equipment to telecom carriers, cable operators, enterprises and utility/alternative carriers. Major lines include fiber-to-the-home (FTTH) access platforms and OLT/ONU gear, optical transport and packet-optical/metro-edge systems, residential and business gateways, Wi-Fi routers and access points, and cloud-managed networking software and services. It positions its platforms around open, disaggregated architectures; the case data's accused products (SDG 834-5 Gateway, EVO6700AP) sit in its Wi-Fi gateway/access-point line. ADTRAN also owns ADTRAN Networks SE (the former ADVA) and operates a broad international sales footprint.

Patent-litigation posture. Adtran is a pure defendant in our database: 1 tracked case, 0 as plaintiff. That pattern — an operating company with products to sell, attacked rather than asserting — is typical of a practicing company defending against patent assertion. The single tracked suit was filed in the Northern District of Alabama, Adtran's home district, rather than a plaintiff-friendly venue such as the Eastern District of Texas.

Notable case. CommWorks Solutions Inc v. Adtran Inc (5:23-cv-01327, N.D. Ala., filed Oct. 3, 2023) was brought by CommWorks Solutions, an entity characterized by third-party litigation analytics (PatSnap; DCT/Ex Parte party data) as a non-practicing patent assertion entity. It asserted six U.S. patents — including US 6,891,807, US RE44,904, US 7,027,465, US 7,177,285, US 7,463,596 and US 7,911,979 — covering time-based wireless access provisioning and priority-traffic detection, targeting Adtran's Wi-Fi gateways and access points and their WPS/WMM functionality. Adtran moved to dismiss in November 2023; the case ended in a voluntary dismissal without prejudice in April 2024, with no merits ruling.
