“ITC complaint,” “investigation launched,” “invalidation trial filed,” “KRW 2 trillion settlement.” Battery patent dispute news mixes procedures whose names sound alike but that fight over entirely different things.
Claim 1 of Vieworks’ US11378527B2 contains no detector and no algorithm. It stacks rotating stages three deep instead. An element-by-element breakdown of the claim axis and design-around points.
In-line total CT is entering 46-series cylindrical production lines. How the bottleneck moved from decision algorithms to tact time and handling mechanisms — and why the claims followed.
Samsung SDI’s US2025/0112325A1 splits the housing cover in two and puts an air gap between the layers. An element-by-element breakdown of claim 1, its real axis, and the design-around points.
Lithium sulfide accounts for 80-90% of a sulfide solid electrolyte BOM. A reading of the Q3 2026 hundred-tonne pilot commissioning through cost structure and the process claims of US11183708B2.
US7967256B2 (Lockheed Martin Corp, priority 2007-05-08, granted 2011-06-28) places a variable-conductance heat pipe’s reservoir next to the radiator so sunlight closes the heat path on its own. We break down all 7 claims by element to map the design-around points and the patent’s expiration strategy.
Hyundai Motor has established a high-nickel cathode active material (CAM) partnership with Umicore. The stated goal is to secure a local sourcing base for compliance with the EU’s Critical Raw Materials Act (CRMA).
QuantumScape’s solid-state battery is a hybrid: on the anode side ions travel through a solid ceramic separator, while on the cathode side they travel through a ‘catholyte’ (a liquid electrolyte dedicated to the cathode).
The real battleground for solid-state batteries is the electrolyte. This piece compares the sulfide, oxide, and polymer pathways and lays out why Samsung SDI is focusing on sulfide.
What separates LEO satellite batteries from ground cells is not energy density, but the impossibility of maintenance and the heat-rejection path. Using a requirements comparison table and the patent landscape around satellite power systems, this piece identifies what asset battery companies actually need to carry into space.
