What this shows Korea's Innovation Score is 37.9/100 (top 42% 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.

Does more volume mean deeper claims for Korea?

Each dot is one of Korea’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Korea’s own 13.2 claims/patent is ABOVE the 11.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Korea's grants concentrate

Korea East-west Power Co., Ltd. is a focused PatentsView assignee: 14 CPC subclasses with 50% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2017. By volume, Korea sits between Kolon Global Corporation and Koto Holdings Limited.

Korea's three-year grant acceleration

Korea East-west Power Co., Ltd. shows 3 grants in 2022–2024 against only 2 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.
