What this shows Kyung's Innovation Score is 46.9/100 (top 20% 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 Kyung's grants concentrate

Kyung Chang Industrial Co., Ltd. is a focused PatentsView assignee: 21 CPC subclasses with 42.4% of grants classified under G05G (Control Devices OR Systems Insofar AS Characterised BY Mechanical Features Only). Peak complete grant year is 2022 (11 grants) versus a trough of 1 in 2019. By volume, Kyung sits between Instrumentation Laboratory and Microfabrica Inc..

Kyung's three-year grant acceleration

Kyung Chang Industrial Co., Ltd. shows 20 grants in 2022–2024 against only 15 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.
