When the U.S. Patent and Trademark Office issued its grants on April 7, 2026, fifteen of them carried Ford Global Technologies as the assignee. Read individually they are ordinary vehicle-engineering patents; read together they trace a coverage map across the part of an electric vehicle that costs the most to build and is hardest to differentiate on: the traction-battery pack and the power it moves.

The anchor of the cluster is US12595693B2, "Traction battery securing assembly and method," which covers a pack enclosure built from a tray and a lid, with a cross-member inside the interior and a touch latch securing the tray or lid to that cross-member. The claim is mechanical and specific: it is about how the modules are held in place and how the box is closed. A companion grant the same day, US12597662B2 ("Traction battery pack enclosure patch and enclosure patching method"), covers a patch secured to the corner area of the same kind of lid-and-tray enclosure. The two grants sit in the same CPC neighborhood — B60K 1/04 and the H01M 50 enclosure classes — and indicate that Ford's filings here address not only how the pack is assembled but how a damaged enclosure is repaired.

The chemistry layer

One layer deeper, two grants cover the cathode material itself. US12597606B2 and US12597602B2 are both titled "Lithium and manganese rich positive active material compositions," and both describe a positive-electrode active material defined by an explicit chemical formula. Lithium-and-manganese-rich layered oxides are a class that swaps some of the cobalt and nickel that dominate today's high-energy cathodes for cheaper manganese, and the two grants land in the H01M 4/525 and H01M 10/0525 classes that cover that lithium-ion cathode and cell space. Having the enclosure patents and the cathode-formula patents issue on the same day, to the same assignee, shows coverage that runs from the chemistry of the cell out to the box that holds it.

A positive electrode active material includes a compound represented by formula 1: Li(1.333-0.667x-y)Mn(0.667-0.333x)NixMyO2 or Li(4/3-2/3x-y)Mn(2/3-1/3x)NixMyO2 (1) wherein, M is Co, Cr, or a combination thereof, 0.13<x<0.5; and 0<y<0.333.— Lithium and manganese rich positive active material compositions, US12597606B2

The third theme in the batch is what happens to the energy once it is stored. US12594852B2 ("Bidirectional energy transfer system and method utilizing a cordset") covers a cordset that transfers power from a device into a traction-battery array under one condition and from the array back to the device under a second condition — the technical substrate of vehicle-to-load and vehicle-to-home features. Alongside it, US12594850B2 covers prioritizing vehicle charging using energy from renewable or low-carbon sources, scheduling when a vehicle charges or exports based on a real-time grid-emissions mixture. Both grants fall in the B60L 53 and B60L 55 charging and bidirectional-transfer classes.

What the issued claims add up to

Rounding out the day's electrified-vehicle grants are two powertrain-control patents — US12594840B2, on recovering from torque-reduction control, and US12594839B2, on controlling the low-voltage bus in an electrified vehicle — both in the B60L 15/20 motor-control class. A granted claim is enforceable coverage, not a product announcement, and these are narrow, implementation-level claims rather than broad platform patents. But the spread is the signal: across a single grant date, Ford's issued patents now touch the enclosure that holds the pack, the cathode chemistry inside it, the cordset that moves power in and out, and the control logic that governs the motor. That breadth across the layers of one subsystem is the kind of footprint that raises the freedom-to-operate questions a competitor's engineers have to clear before shipping a comparable pack.

The broader Ford footprint in this window reinforces the read. Of the fifteen grants that issued April 7, the cluster around B60L (electric propulsion), B60K 1/04 (battery arrangement), and H01M (cells and enclosures) is the densest — eight of the fifteen carry at least one of those classifications. The remainder spread across sensor housings (US12596178B2), pose estimation for perception (US12597158B2), and body hardware. For a company whose financial filings have repeatedly flagged the cost of its electric-vehicle unit, a grant batch this concentrated in the battery pack is a record of where the patent spend has been pointed.
