What this shows Korea's Innovation Score is 46.0/100 (top 22% 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 13.3 claims/patent is ABOVE the 10.0 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 Wheel Corporation is a focused PatentsView assignee: 8 CPC subclasses with 55.6% of grants classified under B65G (Transport OR Storage Devices, e.g. Conveyors FOR Loading OR Tipping, Shop Conveyor Systems OR Pneumatic Tube Conveyors). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2021. By volume, Korea sits between Koei Chemical Company, Limited and KPS Global LLC.

Korea's three-year grant acceleration

Korea Wheel Corporation shows 8 grants in 2022–2024 against only 1 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.
