What this shows K-marine's Innovation Score is 40.4/100 (top 36% 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 K-marine?

Each dot is one of K-marine’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). K-marine’s own 4.2 claims/patent is at or below the 13.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where K-marine's grants concentrate

K-marine Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 50% of grants classified under B63B (Ships OR Other Waterborne VESSELS; Equipment FOR Shipping). By volume, K-marine sits between Juicero, Inc. and K1 Medical Technologies, LLC.

K-marine's three-year grant acceleration

K-marine Co., Ltd. shows 4 grants in 2022–2024 against only 0 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.
