This piece analyzes, via a claim chart, the elements of KR101899991B1 — a tension-control patent for the secondary-battery winding process that even accounts for the rotational moment of inertia of idle rollers — and identifies possible design-around approaches.
Comparing two patents that judge electrode tab-lead weld quality — TechDial’s X-ray + deep learning inspection device (KR102920584B1) and LG Energy Solution’s ultrasonic + AI monitoring application (KR20230040581A) — element by element at the claim level.
KR102164921B1 (Korea Institute of Ceramic Engineering and Technology; filed December 29, 2017; granted October 13, 2020) is a patent that seeks to simplify “pre-doping,” the most demanding process in lithium-ion capacitors, by loading lithium into the binder.
LG Energy Solution’s international application WO2026038783A1 seeks to solve the problem of manganese-rich LMR cathode material fracturing during electrode rolling by mixing two types of LMR particles of different sizes with one type of single-particle NCM particle.
In the era of unmanned distribution-line ESS, fire detection and cooling control are split across two separate patents. This piece maps the claims of KR102254734B1 and KR102406230B1 element by element to analyze the scope of rights and the room for design-around.
Breaking down, element by element, the claims of KR102563230B1 — an AI vision defect-detection patent registered for PCB inspection — this piece analyzes the infringement risk and design-around scenarios that arise when it is extended to battery electrode inspection equipment.
The real contest in anode-free batteries is not “removing the anode material” but “what takes over the job the anode material used to do — receiving lithium evenly.”
Above the LG Energy Solution–EVE Energy ITC investigation sits a higher layer: Tesla’s foundational tabless patent (US11749842B2). Mapping Claim 1’s elements into a claim chart, this piece examines the design freedom available to companies adopting the 46-series format.
This piece maps LG Energy Solution’s dual slot-die coater patent US20250375790A1 against its claim elements in a Claim Chart, and lays out design-around scenarios and FTO checkpoints.
Through DA Technology’s registered patent KR102430493B1, this piece examines the claim scope of a secondary-battery laser-notching system, its gap-guard design, and the possibilities for FTO and design-around.
