This landscape identifies 11 published patent families that combine lithium iron phosphate (LFP) chemistry with active thermal-management claims under the core battery-cooling IPC codes. That is a small, still-forming set compared with LFP chemistry patenting broadly, because the search deliberately narrows to cooling, thermal-runaway prevention and cell-cooling claims rather than electrode or electrolyte composition. Readers should treat this as a focused technical slice, not a count of all LFP-related patent activity.

No single company dominates this dataset. Green Cubes Technology, LLC holds the most detailed corporate filing, a BMS-integrated heating and cooling system, while the most-cited record, CN110534843A, comes from a separate Chinese filer. The most recently active names are a cluster of individual inventors — Gaurav Deshwal, Arun Kapur, Abhishek Wadkar and Santosh Chavan — who co-file together but have not yet consolidated under a single corporate assignee.

Conventional cell cooling, which dominates this dataset through H01M-classified filings, typically routes coolant or air past the outside of the cell or module to remove heat. Immersion cooling submerges cells directly in a dielectric fluid, giving more uniform contact but raising different sealing, fluid-compatibility and serviceability questions. In this landscape immersion cooling appears as a named search term but has almost no dedicated filings, making it one of the more open sub-areas for new claims.

The 2022 midpoint shows zero filings in this dataset, sitting between a 2021 peak of 5 and renewed activity afterward. This is very likely a publication-lag artefact rather than a genuine pause: patent applications typically publish around 18 months after filing, so filings made in late 2021 and through 2022 may simply not have published yet at the time of this data cut. The safest reading is that recent years, including 2022, understate true filing activity.

US20230187734A1, assigned to Green Cubes Technology, LLC, covers a battery management system that monitors and controls dedicated heating and cooling elements within an LFP battery pack, including optional phase-change materials, heating elements and thermoelectric devices built into the cell housing. It is a system-level, BMS-controlled architecture rather than a claim on any single cooling mechanism in isolation. New entrants working on standalone immersion cooling, external HVAC coupling, or passive-only phase-change designs without the described BMS control loop have room to design around it, though a full claim chart is needed before relying on that reading.

China and India each account for 3 of the 11 records in this dataset, ahead of Europe's 2, with single filings in Canada, the United States and via the WIPO PCT route. That distribution suggests filing activity is following manufacturing footprint rather than concentrating through one dominant jurisdiction, which is consistent with LFP cell and pack production being centred in Asia.
