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.
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
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-filingValtrus 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 openDigital 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 securedValtrus 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
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.
US7031870B2 and Six Further Patents — Data Center Cooling and Infrastructure
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.
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.

Portfolio viewWhat 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.
Vertiv’s intervenor role reveals upstream IP liability in data center supply chains
Vertiv’s intervention — and the explicit carve-out of Vertiv’s independent claims — suggests infrastructure OEMs face direct assertion risk when their technology is deployed by end-user operators. Suppliers should evaluate indemnification obligations and monitor downstream enforcement activity carefully.
Judge Gilstrap’s EDTX docket creates strategic timing pressure for licensing campaigns
Cases before Judge Gilstrap in the Eastern District of Texas move at a pace that accelerates cost exposure for defendants. The 195-day resolution here is consistent with settlement pressure created by EDTX scheduling orders. Defendants in EDTX patent cases should build early case assessment and FTO clearance into their pre-litigation playbook.
Valtrus v Digital — key questions answered
Valtrus asserted seven U.S. patents: US7031870B2, US6862179B2, US7939967B2, US6854287B2, US6718277B2, US7339490B2, and US9310855B2. The patents cover data center technologies including atmospheric control, cooling systems, air re-circulation indexing, modular deployment, sensor assemblies, power supply control, and cooling fluid partitioning.
The case was dismissed with prejudice pursuant to a joint motion filed by all parties, including intervenor Vertiv Corporation. The dismissal covered all claims and counterclaims in member cases 2:24-CV-00535-JRG and 2:24-CV-00139-JRG. The joint nature and own-costs provision are consistent with a privately negotiated resolution. The public record does not disclose financial terms.
No. The court’s order explicitly directed the Clerk to maintain lead case 2:24-CV-00361-JRG as open. The dismissal was expressly limited to claims involving Digital Realty Trust and related Vertiv intervenor claims. Valtrus’s enforcement campaign against other defendants in the data center sector continues.
Vertiv Corporation participated as an intervenor. The joint motion and court order indicate that Vertiv’s claims were dismissed only to the extent they concerned Digital Realty’s use of Vertiv technology. The order explicitly preserved Vertiv’s independent claims not tied to Digital Realty’s use, suggesting Vertiv retains exposure or standing in related proceedings.
A dismissal with prejudice on ‘all claims that were or could have been brought’ constitutes a final adjudication for claim-preclusion purposes. Valtrus is barred from re-asserting the same seven patents against Digital Realty Trust for the same accused products in any future action. This provides Digital Realty with a strong preclusion shield on the specific claims resolved in this member case.
