Ciena Communications, Inc.

Company overview. Ciena Communications, Inc. is a wholly owned subsidiary of Ciena Corporation (NYSE: CIEN), a Delaware corporation headquartered at 7035 Ridge Road, Hanover, Maryland. Ciena was founded in 1992 and is publicly traded; per its fiscal 2025 Form 10-K and year-end results, it reported approximately $4.77 billion in revenue for the fiscal year ended November 1, 2025, with roughly 9,000 employees.

Products / services / operations. Ciena is a network technology company selling hardware, software, and services to cloud providers, communications service providers, cable/MSOs, governments, research-and-education networks, and enterprises. Reported segments are Networking Platforms (optical networking — 6500 Packet-Optical Platform, 6500 Reconfigurable Line System, Waveserver, coherent pluggables — plus routing and switching), Platform Software and Services, Blue Planet automation software for OSS/service lifecycle management, and Global Services. This is an operating company, not a patent-assertion entity.

Patent-litigation posture. Ciena Communications appears in the tracked data as a defendant in one case and never as a plaintiff — the signature of an operating company being attacked rather than an active two-way litigant. The single tracked matter is Fiber, LLC v. Ciena Corporation et al., filed in the U.S. District Court for the District of Colorado (Denver), consistent with the plaintiff's Denver base rather than a plaintiff-friendly Texas venue.

Notable case context. Plaintiff Fiber, LLC, a Wyoming LLC with a Denver office, styled itself the exclusive assignee of U.S. Patent Nos. 6,430,332 and 7,095,917, covering optical switching apparatus (beam-directing/MEMS-mirror and LCOS implementations), and asserted them against multiple optical-networking vendors including Ciena, NEC, Viavi/JDS Uniphase, Lumentum, Alcatel-Lucent, and Finisar. The Ciena actions (13-cv-00840, consolidated with 15-cv-01743 and 15-cv-02135) ended with a September 13, 2018 final judgment of invalidity and non-infringement after the court found the "control" limitation indefinite at claim construction (Sept. 6, 2017); the Federal Circuit affirmed in November 2019 (No. 19-1005).
