Valtrus Innovations v. CyrusOne: 7-Patent Data Center Suit Ends With Prejudice
Valtrus Innovations and Key Patent Innovations sued CyrusOne, LLC in the Eastern District of Texas, asserting seven patents covering data center cooling systems, atmospheric control, and modular infrastructure. The case was dismissed with prejudice by joint motion after just 133 days, with each party bearing its own costs — consistent with an undisclosed settlement.
Seven-Patent Data Center Cooling Suit Resolves Swiftly in E.D. Texas
Filed on 12 July 2024 in the Eastern District of Texas before Judge Rodney Gilstrap, this infringement action saw Valtrus Innovations, Ltd. and co-plaintiff Key Patent Innovations Ltd. assert seven patents against data center operator CyrusOne, LLC. The patents span atmospheric control within buildings, cooling systems, data center air re-circulation indexing, flexible and modular deployment architectures, sensor assemblies, multiple power supply control, and cooling fluid partitioning — collectively covering core operational technologies used in modern hyperscale and colocation data centers.
The case closed on 22 November 2024 after just 133 days, via a Joint Motion to Dismiss with Prejudice that also covered the related member case 2:24-cv-00259. Notably, Vertiv Corporation appeared as an intervenor and joined the motion alongside the primary parties. Judge Gilstrap granted the motion and ordered all claims and counterclaims dismissed with prejudice, meaning neither side can re-litigate the same assertions. Each party was directed to bear its own costs, attorneys’ fees, and expenses.
The speed of resolution — roughly four months from filing to closure — and the each-party-bears-own-costs structure are consistent with a confidential settlement, though the public record does not confirm this. The involvement of Vertiv Corporation as an intervenor suggests the dispute had supply-chain or equipment-manufacturer dimensions that extended beyond the direct plaintiff-defendant relationship. The lead case (2:24-CV-00361-JRG) was ordered to remain open, indicating broader litigation by Valtrus in the same court continues.

Dismissed with prejudice: what the joint order means for both parties
Dismissal with prejudice extinguishes all claims permanently
A dismissal with prejudice is a final adjudication on the merits — it bars Valtrus and Key Patent Innovations from ever re-asserting the same claims against CyrusOne on these seven patents. The joint nature of the motion means both sides agreed to this finality, which courts in the Eastern District of Texas routinely grant without further scrutiny. All pending relief requests were denied as moot.
Permanent bar on re-filingValtrus permanently waives claims against CyrusOne on these patents
By joining the dismissal with prejudice motion, Valtrus and Key Patent Innovations surrendered the right to sue CyrusOne again on US7031870B2 and the six co-asserted patents. This is typically consistent with a licensing deal or covenant not to sue, where the value was realised outside the courtroom. The patents themselves remain valid and enforceable against other defendants — as evidenced by the lead case remaining open.
Patents remain live vs. othersCyrusOne obtains full finality on all seven patent claims
CyrusOne, represented by Kirkland & Ellis across multiple offices, secured dismissal with prejudice on all claims and counterclaims that were or could have been brought in this member case. This provides robust protection against re-litigation by Valtrus on these specific patents. The each-party-bears-own-costs order avoided any fee-shifting exposure for CyrusOne under 35 U.S.C. § 285.
No fee-shifting orderedVertiv’s intervenor role signals equipment-layer complexity
Vertiv Corporation’s status as an intervenor — and a signatory to the joint dismissal motion — suggests the cooling and power infrastructure covered by these patents implicates data center equipment suppliers, not just operators. Data center developers and colocation providers evaluating similar technologies from Vertiv or comparable vendors should assess whether any licensing resolution here carries downstream implications for their own freedom to operate.

Official order — verbatim text
The Court’s order adopts the joint motion’s language without modification, granting dismissal with prejudice across both member cases and explicitly preserving the lead case. The phrase ‘all claims and counterclaims that were, or could have been, brought’ is standard preclusion language that forecloses not only the asserted claims but any related patent claims that could have been joined. The each-party-bears-own-costs term is commercially neutral and provides no signal as to which party extracted greater concessions in any underlying negotiation.
US7031870B2 — Data Center Cooling & Infrastructure Patent Portfolio
The seven patents at issue — US7031870B2, US6862179B2, US7939967B2, US6854287B2, US6718277B2, US7339490B2, and US9310855B2 — collectively cover foundational data center operational technologies. The portfolio spans atmospheric and environmental control within facilities, cooling system hardware and management, air re-circulation index-based evaluation, modular and flexible data center deployment, sensor assemblies, power supply management, and cooling fluid partitioning. Application dates range across the early-to-mid 2000s through the early 2010s, placing these inventions at the emergence of modern hyperscale data center architecture.
Valtrus Innovations, believed to be an IP monetisation vehicle associated with former Hewlett-Packard enterprise IP, holds a portfolio with significant coverage of data center infrastructure fundamentals. The breadth of this seven-patent assertion — covering both physical cooling hardware and management/evaluation methodologies — reflects a strategy of surrounding a defendant’s entire operational stack. For any colocation or cloud operator deploying conventional air or liquid cooling architectures, at least some claims in this portfolio are likely to warrant independent FTO review.
Should you run an FTO against US7031870B2 and the Valtrus data center portfolio?
Any company designing, deploying, or operating data center cooling infrastructure — particularly colocation providers, hyperscale operators, and data center equipment manufacturers — should consider a freedom-to-operate assessment against this portfolio. The seven patents cover technologies that are near-ubiquitous in modern facilities: atmospheric control, modular deployment, air re-circulation management, and power distribution. Vertiv’s intervention in this case illustrates that exposure is not limited to operators; equipment suppliers may also face direct or indirect assertion risk.

What this case signals for the data center infrastructure IP landscape
A seven-patent E.D. Texas filing resolved in 133 days with an intervenor signals active monetisation pressure on data center operators.
Valtrus is actively enforcing data center cooling patents in E.D. Texas
This case is one of multiple member cases filed by Valtrus in the Eastern District of Texas before Judge Gilstrap. The lead case (2:24-CV-00361) remains open, confirming an ongoing enforcement campaign. Colocation operators and hyperscale data center builders should treat these seven patents as live licensing risk, particularly those using atmospheric control or liquid/air cooling partition technologies.
Equipment intervenors signal that IP risk travels up the supply chain
Vertiv Corporation’s intervention suggests that data center operators facing these patent assertions may look to equipment suppliers for indemnification or shared defence. Companies procuring cooling infrastructure should audit their vendor agreements for IP indemnity clauses covering the patent families asserted here — particularly US7031870B2 and US6854287B2.
Valtrus v CyrusOne — key questions answered
Valtrus Innovations asserted seven patents: US7031870B2, US6862179B2, US7939967B2, US6854287B2, US6718277B2, US7339490B2, and US9310855B2. These cover data center atmospheric control, cooling systems, air re-circulation evaluation, modular deployment, sensor assemblies, power supply control, and cooling fluid partitioning.
The case was dismissed with prejudice pursuant to a joint motion signed by both parties and intervenor Vertiv Corporation. Dismissal with prejudice is a permanent resolution — Valtrus cannot re-assert the same claims against CyrusOne on these patents. It is consistent with, though does not confirm, an undisclosed settlement or licensing agreement.
The public record does not specify Vertiv’s basis for intervention, but its participation as a signatory to the joint dismissal motion suggests Vertiv had a direct interest in the resolution — likely as a supplier of data center cooling equipment implicated by the asserted patents. Equipment suppliers are frequently drawn into data center IP disputes through indemnification obligations or direct infringement exposure.
CyrusOne was represented by Kirkland & Ellis LLP across multiple offices, with attorneys Gregory S. Arovas, Matthew J. McIntee, Peter Jason Evangelatos, Sean M. McEldowney, and Todd M. Friedman listed as counsel. Kirkland & Ellis is a leading patent litigation defence firm frequently retained in high-stakes E.D. Texas patent cases.
Not entirely. Member cases 2:24-cv-00534 and 2:24-cv-00259 against CyrusOne were dismissed with prejudice, but the lead case 2:24-CV-00361-JRG was expressly ordered to remain open by the Court. This indicates Valtrus’s broader enforcement campaign in the Eastern District of Texas involving data center patents continues against other defendants.
