What this shows Korean's Innovation Score is 31.4/100 (38th percentile 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 Korean?

Each dot is one of Korean’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). Korean’s own 4.4 claims/patent is at or below the 8.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Korean's grants concentrate

Korean AIR Lines Co., Ltd is a focused PatentsView assignee: 13 CPC subclasses with 28.6% of grants classified under B64U (Unmanned Aerial Vehicles [UAV]; Equipment Therefor). Peak complete grant year is 2016 (7 grants) versus a trough of 1 in 2015. By volume, Korean sits between Kitagawa Ironworks Co., Ltd. and Kyocera Mita Corporation.

Korean's three-year grant acceleration

Korean AIR Lines Co., Ltd shows 2 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.
