Valtrus and KPI filed Valtrus Innovations Ltd. et al. v. Sabey Data Center Properties LLC in the Eastern District of Virginia on August 18, 2026. The case was transferred to the Eastern District of Texas and received there on September 11, 2026, as No. 2:26-cv-00807. The complaint describes an HPE-origin portfolio. A related complaint against FifteenFortySeven Critical Systems Realty, LLC (No. 2:26-cv-00820) asserts U.S. Patents 6,854,287 and 6,868,682.

Patents and accused products

Against Sabey, the complaint asserts U.S. Patent 6,868,682, titled Agent based control method and system for energy management, and U.S. Patent 6,718,277, titled Atmospheric control within a building. The complaint ties infringement to Sabey's use of datacenter cooling equipment (including Vertiv gear referenced in the complaint) to cool and monitor its facilities. The FifteenFortySeven complaint adds U.S. Patent 6,854,287, titled Cooling system.

What the patents cover

U.S. Patents 6,868,682 and 6,718,277 cover managing energy and air conditions inside buildings and computer rooms - sensing conditions, comparing them to templates or control goals, and adjusting cooling.

U.S. Patent 6,868,682 covers controlling data-center temperature with a hierarchy of agents: a first agent adjusts cooling-fluid delivery to keep a subsystem in range, escalates to a second agent to redistribute cooling when needed, and a third agent varies cooling-fluid output if the first two cannot hold the range.

Asserted claims of the '682 patent (Sabey). At least claim 1.

Claim 1 covers controlling data-center temperature with a hierarchy of agents: a first agent reads temperature sensor data, adjusts cooling-fluid delivery to stay in range, and escalates to a second agent when it cannot keep the subsystem in range.

U.S. Patent 6,718,277 covers controlling atmospheric conditions in a building by supplying conditioned fluid, sensing atmospheric parameters at various locations, building an empirical map, comparing it to a template map, and varying quantity, quality, or distribution of the conditioned fluid to reduce the differentials.

Asserted claims of the '277 patent (Sabey). At least claim 1.

Claim 1 covers controlling building atmosphere by supplying conditioned fluid, sensing atmospheric parameters at many locations, building an empirical atmospheric map, comparing it to a template map, and flagging pattern differences.

U.S. Patent 6,854,287 (asserted against FifteenFortySeven) covers cooling a computer room with a heat exchanger that receives and returns room air, supplied with cooling fluid, where cooling fluid temperature or air delivery is controlled in response to temperatures sensed in the room.

Asserted claims of the '287 patent (FifteenFortySeven). At least claim 1.

What the lawsuit is about

Valtrus is running a cluster of EDTX datacenter-cooling suits against operators, accusing the way they run facility cooling and energy-management systems. Sabey is the lead example with the '682/'277 pair.

What it means

These patents are older HPE-origin cooling patents, so damages timing will matter. On September 14, 2026, the court granted Sabey an extension to answer through October 13, 2026 (ECF No. 11).

What to watch next

Watch for related-case practice across the Valtrus EDTX cluster and for defendants' answers. Also watch whether Valtrus names additional datacenter operators on the same patents.
