Valtrus Innovations v. Digital Realty Trust: 7-Patent Data Center Cooling Case Dismissed With Prejudice

Valtrus Innovations and Key Patent Innovations filed a multi-patent infringement action against data center operator Digital Realty Trust in the Eastern District of Texas, asserting seven patents covering cooling systems, atmospheric control, and modular data center infrastructure. The parties jointly moved to dismiss all claims with prejudice after 195 days, with each side bearing its own costs — a resolution that typically signals a private settlement reached without court-imposed terms.

Case overview

Seven-Patent Data Center Infrastructure Dispute Ends in Coordinated Exit

Valtrus Innovations Ltd. and Key Patent Innovations Ltd. filed this action on July 12, 2024 in the Eastern District of Texas before Judge Rodney Gilstrap, asserting seven U.S. patents against Digital Realty Trust, Inc. — one of the world’s largest data center operators. The patents-in-suit span a broad range of data center infrastructure technologies, including atmospheric control within buildings, cooling systems, air re-circulation index evaluation, flexible and modular data center deployment, modular sensor assemblies, multiple power supply control, and partition-based cooling fluid management.

The case was dismissed with prejudice on January 23, 2025, pursuant to a joint motion filed by all parties — including intervenor Vertiv Corporation. The court’s order explicitly dismissed all claims and counterclaims that were or could have been brought in member cases 2:24-CV-00139-JRG and 2:24-CV-00535-JRG. Notably, the dismissal was expressly limited to claims involving Digital Realty Trust as defendants, with the lead case (2:24-CV-00361-JRG) remaining open, suggesting Valtrus’s broader litigation campaign continues against other defendants.

The 195-day timeline and mutual cost-bearing arrangement are consistent with a negotiated commercial resolution reached before substantial litigation expenses accumulated. The joint nature of the motion — including participation by intervenor Vertiv — suggests the settlement addressed supply-chain complexity, given Vertiv’s role as a technology provider whose equipment was implicated in Digital Realty’s alleged infringement. The public record does not disclose any financial terms, licence grants, or ongoing obligations. The retention of the lead case against other defendants signals Valtrus’s continued assertion strategy across the data center sector.

Dismissed with prejudice: what the joint exit means for both parties

Legal mechanism

Dismissal with prejudice bars re-filing on the same claims

A dismissal with prejudice under Federal Rule of Civil Procedure 41 is a final adjudication on the merits for claim-preclusion purposes. Valtrus cannot re-assert these same seven patents against Digital Realty Trust on the same accused products in a future action. The joint nature of the motion — filed by plaintiffs, defendants, and intervenor Vertiv together — indicates a negotiated resolution rather than a unilateral concession by either side.

Permanent bar on re-filing
Plaintiff outcome

Valtrus closes Digital Realty chapter while preserving broader campaign

For Valtrus, dismissal with prejudice as to Digital Realty Trust does not impair its ongoing assertions against other defendants in lead case 2:24-CV-00361-JRG. The resolution is consistent with extracting value from Digital Realty — potentially through a licence or lump-sum payment — while maintaining litigation leverage against remaining defendants. The own-costs arrangement avoids any fee-shifting risk that could arise from prolonged proceedings.

Lead case remains open
Defendant outcome

Digital Realty exits with full preclusion shield on seven patents

Digital Realty Trust obtains a with-prejudice dismissal covering all claims that were or could have been brought — a broad preclusion that protects against future infringement assertions on these seven patents for the accused products. The inclusion of Vertiv as intervenor and the explicit carve-out of Vertiv’s independent claims (other than those tied to Digital Realty’s use) suggests the supply-chain liability question was resolved as part of the exit package.

Full claim preclusion secured
Commercial implications

Valtrus portfolio signals continued pressure on data center operators

With seven patents spanning cooling architecture, power management, and modular deployment — all core to hyperscale data center operations — Valtrus’s portfolio represents sustained monetisation risk for the sector. The lead case remaining open against at least one other defendant suggests a coordinated licensing campaign. Data center operators and their infrastructure suppliers should treat this dismissal as a signal of ongoing assertion activity, not the end of Valtrus’s enforcement posture.

Official order — verbatim text

“Before the Court is the Joint Motion to Dismiss in Part Only with Respect to Defendants Digital Realty Trust, Inc. and Digital Realty Trust, L.P. (the “Motion”) filed by Plaintiffs Valtrus Innovations, Ltd. and Key Patent Innovations Ltd. (collectively, “Plaintiffs”), Defendants Digital Realty Trust, Inc. and Digital Realty Trust, L.P. (collectively, “Defendants”), and Intervenor Vertiv Corporation (“Vertiv” and with Plaintiffs and Defendants, the “Parties”). (Dkt. No. 94.) In the Motion, the Parties “jointly move to dismiss the above-captioned matters in part with respect Case 2:24-cv-00535-JRG Document 6 Filed 01/23/25 Page 1 of 2 PageID #: 294 2 to the cases involving . . . Defendants only, including Vertiv as intervenor in those cases, with prejudice.” (Id. at 1–2.) Specifically, the Parties request that the Court dismiss “all claims and counterclaims that were or could have been brought in the actions between Plaintiffs and . . . Defendants only, including as it concerns Vertiv’s role as Intervenor” in Member Case Nos. 2:24- CV-00139-JRG and 2:24-CV-00535-JRG. (Id. at 2.) The Parties further state that “[n]othing in this Motion is meant to resolve Intervenor Vertiv’s claims other than with respect to . . . Defendants’ use of Vertiv technology.” (Id.) Having considered the Motion, and noting its joint nature, the Court finds that it should be and hereby is GRANTED. Accordingly, all claims and counterclaims that were or could have been brought in Member Case Nos. 2:24-CV-00139-JRG and 2:24-CV-00535-JRG are hereby DISMISSED WITH PREJUDICE. Each party is to bear its own costs, expenses, and attorneys’ fees. All pending requests for relief in Member Case Nos. 2:24-CV-00139-JRG and 2:24-CV00535-JRG not explicitly granted herein are DENIED AS MOOT. The Clerk of Court is directed to CLOSE Member Case Nos. 2:24-CV-00139-JRG and 2:24-CV-00535-JRG and MAINTAIN AS OPEN Lead Case No. 2:24-CV-00361-JRG.”
Source: PACER Docket, Case 2:24-cv-00535, Texas Eastern District Court

The court’s order grants a joint motion to dismiss with prejudice all claims and counterclaims in member cases 2:24-CV-00535-JRG and 2:24-CV-00139-JRG. The explicit instruction that ‘all claims . . . that were or could have been brought’ are dismissed is characteristic of a broad, negotiated exit designed to foreclose future litigation between these specific parties. The own-costs provision is neutral and does not suggest weakness by either side. Critically, the order’s direction to close only the member cases — while maintaining lead case 2:24-CV-00361-JRG — confirms that Valtrus’s enforcement campaign extends beyond Digital Realty Trust.

The seven asserted patents collectively cover foundational data center infrastructure technologies developed during the early-to-mid 2000s, with application dates ranging from 2002 to 2009. The portfolio addresses atmospheric and thermal management within large-scale computing facilities — including air re-circulation indexing (US7031870B2), cooling system design (US6862179B2), power supply control (US7939967B2), cooling fluid partition management (US6854287B2), modular deployment (US6718277B2), sensor assemblies (US7339490B2), and atmospheric control (US9310855B2). These patents originate from legacy research portfolios and are now held by Valtrus, a patent licensing entity.

The strategic significance of this portfolio lies in its breadth across the physical infrastructure stack of a modern data center — from thermal management and airflow optimisation to power distribution and modular design. As hyperscale operators like Digital Realty expand capacity globally, these foundational patents create assertion leverage at scale. Competitors and infrastructure vendors operating in colocation, edge computing, and hyperscale data center deployment should treat the full Valtrus portfolio as an active risk vector, particularly given the continuation of the lead case against additional defendants.

Freedom to operate

Should you run an FTO analysis against US7031870B2 and the Valtrus data center portfolio?

Any company designing, deploying, or operating data center cooling systems, modular infrastructure, or atmospheric control technologies should evaluate freedom-to-operate against the Valtrus portfolio. This is particularly relevant for colocation operators, hyperscale cloud providers, data center REITs, and infrastructure OEMs — including cooling system suppliers, power management vendors, and modular build-out contractors. The ongoing lead case signals active enforcement, and the breadth of the seven-patent portfolio increases the likelihood that multiple product lines may be implicated.

PatSnap Eureka’s FTO Search Agent can map each of the seven Valtrus patents against your specific product architecture, identify claim elements most likely to read on cooling and power management systems, and surface design-around prior art. Eureka’s portfolio monitoring tools can also track new filings by Valtrus and Key Patent Innovations against other defendants, giving IP teams early warning of evolving claim interpretations and litigation posture before they become a direct threat.

Strategic implications

What this case signals for the data center infrastructure IP landscape

Valtrus’s multi-patent campaign against a major REIT operator highlights escalating licensing pressure across cooling and power management technologies.

Dismissal with prejudice as to one defendant does not end portfolio risk

The lead case remains open. Data center operators facing assertion from patent licensing entities should monitor whether their infrastructure vendors — like Vertiv — are named as intervenors, as supply-chain liability can complicate and extend settlement negotiations significantly.

Seven-patent assertions signal a portfolio licensing posture, not a single-patent bet

Asserting patents across cooling, atmospheric control, power supply, and modular deployment creates multiple invalidity vectors for defendants but also makes design-around difficult. Operators should assess exposure across the full Valtrus portfolio, not just the patents in this specific member case.
