What this shows LS's Innovation Score is 68.0/100 (top 1% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Where LS's grants concentrate

LS Electric Co., Ltd. is a focused PatentsView assignee: 42 CPC subclasses with 45.8% of grants classified under H01H (Electric SWITCHES; RELAYS; SELECTORS; Emergency Protective Devices). Peak complete grant year is 2024 (64 grants) versus a trough of 7 in 2021. By volume, LS sits between Acco Brands Corporation and Wabco GmbH.

LS's three-year grant acceleration

LS Electric Co., Ltd. shows 125 grants in 2022–2024 against only 7 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
