What this shows Korea's Innovation Score is 48.8/100 (top 16% 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 Korea's grants concentrate

Korea Kumho Petrochemical Co., Ltd. is a focused PatentsView assignee: 30 CPC subclasses with 43.5% of grants classified under C08F (Macromolecular Compounds Obtained BY Reactions Only Involving Carbon-to-carbon Unsaturated Bonds). Peak complete grant year is 2016 (10 grants) versus a trough of 4 in 2017. By volume, Korea sits between Infinity Pharmaceuticals, Inc. and Muffin Incorporated.

Korea's three-year grant acceleration

Korea Kumho Petrochemical Co., Ltd. shows 19 grants in 2022–2024 against only 14 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.
