Company overview. D-Link Corporation (commonly "D-Link") is a Taiwanese networking-equipment maker headquartered at No. 289, Xinhu 3rd Road, Neihu District, Taipei. Founded in 1986 by Ken Kao, it has been listed on the Taiwan Stock Exchange since 1994 under ticker 2332 (TWSE) and remains publicly traded; in June 2020 it became part of the Taiwan Steel Group conglomerate. Public data (2025–26) indicates roughly 2,700–2,800 employees worldwide, trailing-twelve-month revenue around NT$13.5 billion (~US$0.4 billion), and a market cap of roughly NT$10 billion (~US$0.3 billion). Its U.S. subsidiary, D-Link Systems, Inc., is based in California.
Products / operations. D-Link designs, develops, and markets networking and broadband communications equipment for home, SOHO, SMB, and enterprise customers. Major lines include Ethernet/industrial switches, Wi-Fi routers, mesh systems, access points and adapters, DSL/fiber/5G-LTE broadband gateways, IP security cameras and smart-home devices, plus cloud and AI-managed network services (e.g., mydlink and Nuclias). It spun off its OEM/ODM manufacturing arm in 2003 and sells through distributors, retailers, and service providers across roughly 40–100 countries.
Patent-litigation posture. In the tracked database, D-Link is an operating company appearing only as a defendant (1 case; 0 as plaintiff). It was swept into a suit brought by an operating-company plaintiff rather than a non-practicing entity: Skyworks Solutions Canada, Inc. and Skyworks Global Pte Ltd. sued in the Central District of California (filed May 6, 2024) over allegedly infringing Wi-Fi RF front-end modules and downstream products. D-Link and its U.S. subsidiary were named as downstream defendants alongside module maker Kangxi Communication Technologies, Grand Chip Labs, and Ruijie Networks.
Notable context. The district case was stayed in September 2024 under 28 U.S.C. § 1659 pending the parallel U.S. ITC Section 337 investigation (Inv. No. 337-TA-1413) into the same RF-front-end patents. A January 2026 ITC initial determination reportedly found no infringement by respondent Kangxi, which bore the primary defense. D-Link's involvement reflects its role as an accused downstream customer of the Wi-Fi front-end components, not as an assertion entity; its exposure remains tied to the unresolved ITC appeal proceedings.
