Climate & Energy
Lithium batteries dominate short-duration storage, but storing energy as heat is cheaper for the long haul. A Rondo grant describes coupling a thermal store to a power cycle.

Most battery sensing watches the whole cell from the outside. A GM grant builds a reference electrode into the separator itself, turning the membrane into a diagnostic instrument.

Two grants issued days apart — one for home demand response, one for EV-charging virtual power plants — both put a learning agent in charge of power decisions. The CPC tags show a pattern.

Solid-state battery patents live or die on chemistry specifics. A June 2026 GS Yuasa grant shows the three-layer claim structure that protects an electrolyte: composition, process, and device.

A single power module that serves both AC and DC applications sounds like marketing. The claim language shows the real inventive bet: reconfigurability, not the conversion itself.

Overlapping solar cells like roof shingles squeezes more power from the same area. A Maxeon grant claims the module — and its CPC tags reach all the way to grid connection.

Two active filing clusters — grid-forming converters and reinforcement-learning grid control — sit right next to each other in H02J. The gap between them is the white space.

Trace Enphase's grants and you can watch the unit of invention expand — from one panel's converter, to a home network, to a self-contained portable energy system.

Islanding is easy; reconnecting is hard. An ABB grant on 'participation-factor' resynchronization describes the maneuver that lets a microgrid snap back onto the main grid cleanly.
Climate & Energy
Batteries that both charge from and discharge to the grid need a converter that runs both ways. A Dynapower grant claims the topology — but the word 'bidirectional' hides where the real limitation sits.
Climate & Energy
A grid that goes dark has to be restarted from something. A Dynapower grant describes how to bring multiple converters up in grid-forming mode — the IP behind a real interconnection problem.
Climate & Energy
Two grants issued the same day in October 2025 show Enphase widening from power conversion into whole-home energy management and communications.
Climate & Energy
A new Enphase microinverter patent reads narrower than the marketing. What it actually claims is a specific power-control method — and that distinction matters.
