2 cases as defendant.
CyrusOne, LLC (formerly CyrusOne Inc., NASDAQ: CONE) is a data center developer and operator headquartered in Dallas, Texas. It was founded in 2000 and went public as a REIT in a January 2013 spin-off from Cincinnati Bell. In March 2022, KKR and Global Infrastructure Partners (now part of BlackRock) completed a take-private buyout valued at roughly $15 billion ($90.50/share), so CyrusOne is now privately held by funds managed by those two sponsors. Third-party trackers place headcount at roughly 1,000.
Operations. CyrusOne designs, builds, owns and operates carrier-neutral data centers, offering colocation, hyperscale leasing, build-to-suit and wholesale capacity plus interconnection and peering services to enterprise and cloud customers. Its footprint spans North America, Europe (UK, Germany, Netherlands, Ireland, Italy, Spain) and, more recently, Japan. Public materials describe over 50 facilities serving roughly 1,000 customers, with live capacity in the gigawatt range and additional space in development. It is an operating company, not a patent-holding shell.
Patent-litigation posture. The database shows CyrusOne with zero plaintiff cases and two defendant cases, both in the Eastern District of Texas — the classic profile of an operating company targeted by a non-practicing entity rather than an aggressor. Both tracked suits were brought by Valtrus Innovations Ltd., a patent-assertion entity that acquired a portfolio from Hewlett Packard Enterprise and holds the asserted patents in trust for Key Patent Innovations Ltd.
Notable cases. Valtrus Innovations Ltd. et al. v. CyrusOne, LLC (E.D. Tex., filed 2024-07-12) and a related Valtrus Innovations Ltd. v. CyrusOne, LLC action assert data-center-related patents. CyrusOne's filings in the Valtrus campaign include declaratory-judgment counterclaims of non-infringement. Valtrus has filed similar data-center suits against other operators, including Digital Realty, TierPoint, DataBank and Evoque, and has faced IPR and declaratory-judgment challenges from several defendants. The Valtrus litigation pattern, not CyrusOne's own filings, accounts for all of the company's tracked appearances.
Valtrus Innovations Ltd. and Key Patent Innovations Ltd. sued CyrusOne, LLC in E.D. Tex., with US 7,031,870 at issue. The case was dismissed with prejudice by joint motion on Nov. 22, 2024.
