Valtrus Sues Five Data Center Operators Over Chicago Cooling Patents
Valtrus Innovations filed patent suits against five Chicago-area data center firms over cooling systems.
Why it matters: Data center cooling keeps crucial tech services running. Patent litigation like this forces legal and operations teams to manage IP exposure and plan for operational disruptions.
- Valtrus targets Netrality, Lumen, CoreSite, NTT, and Prime Data Centers in five new lawsuits.
- The claims focus on U.S. Patent Nos. 6,854,287 and 6,868,682 covering cooling hardware.
- Cases were filed in the U.S. District Court for the Northern District of Illinois, Chicago.
- Valtrus previously reached confidential settlements with DataBank Holdings and Equinix in similar disputes.
Valtrus Innovations Ltd., an Irish patent owner, is suing five major U.S. data center operators in the Chicago area. The companies include Netrality Properties LP, Lumen Technologies Inc., CoreSite LLC, NTT Global Data Centers Americas Inc., and Prime Data Centers LLC. These new lawsuits allege infringement of Valtrus’s U.S. Patent Nos. 6,854,287 and 6,868,682 covering data center cooling equipment.
- Valtrus asserts the firms used patented cooling systems without a license, targeting centers crucial for digital operations.
- The lawsuits are filed in the U.S. District Court for the Northern District of Illinois, where the data centers operate.
- In previous actions, Valtrus settled with DataBank Holdings Ltd. and Equinix Inc. in January 2026. Both sides dismissed claims with prejudice after confidential resolutions.
Industry scrutiny over data center patent rights is increasing as uptime and equipment reliability remain top priorities. According to Bloomberg Law, ongoing disputes reflect how patent enforcement is becoming more routine in data center operations.
While the court filings detail the asserted patents, specifics of the alleged unlicensed technology use are not disclosed in the complaints. The DataBank and Equinix settlements also remain confidential, leaving open questions about licensing strategies among data center firms.
By the numbers:
- 5 — Number of companies sued in new filings
- 2 — Key U.S. patents at the center of litigation, both on cooling systems
- 2026 — Year Valtrus settled with DataBank and Equinix
Yes, but: Details of the allegedly infringing technologies and prior settlement terms are not public, limiting transparency into potential impacts.
