What this shows LX's Innovation Score is 68.7/100 (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 LX's grants concentrate

LX Semicon Co., Ltd. is a focused PatentsView assignee: 34 CPC subclasses with 57.1% of grants classified under G09G (Arrangements OR Circuits FOR Control OF Indicating Devices Using Static Means TO Present Variable Information). Peak complete grant year is 2024 (100 grants) versus a trough of 13 in 2022. By volume, LX sits between ZKW Group GmbH and AVL List GMBH.

LX's three-year grant acceleration

LX Semicon Co., Ltd. shows 177 grants in 2022–2024 against only 0 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.
