What this shows Korea's Innovation Score is 49.9/100 (top 14% 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 10.4 claims/patent is ABOVE the 8.2 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 Fuel-tech Corporation is a focused PatentsView assignee: 18 CPC subclasses with 54.5% of grants classified under B60K (Arrangement OR Mounting OF Propulsion Units OR OF Transmissions IN VEHICLES; Arrangement OR Mounting OF Plural Diverse Prime-movers IN VEHICLES; Auxiliary Drives FOR VEHICLES; Instrumentation OR Dashb). Peak complete grant year is 2023 (3 grants) versus a trough of 1 in 2021. By volume, Korea sits between Komico Ltd. and Koyo Machine Industries Co., Ltd..

Korea's three-year grant acceleration

Korea Fuel-tech Corporation shows 4 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.
