What this shows Hanwha's Innovation Score is 47.4/100 (top 19% 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 Hanwha?

Each dot is one of Hanwha’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). Hanwha’s own 8.8 claims/patent is ABOVE the 7.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Hanwha's grants concentrate

Hanwha Ocean Co., Ltd. is a focused PatentsView assignee: 14 CPC subclasses with 91.7% of grants classified under B63B (Ships OR Other Waterborne VESSELS; Equipment FOR Shipping). By volume, Hanwha sits between HYL Technologies, S.A. DE C.V. and Head's Select, Inc..

Hanwha's three-year grant acceleration

Hanwha Ocean Co., Ltd. shows 9 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.
