What this shows Hongduk's Innovation Score is 40.3/100 (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 Hongduk?

Each dot is one of Hongduk’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). Hongduk’s own 4.0 claims/patent is at or below the 4.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Hongduk's grants concentrate

Hongduk Industrial Co., Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 60% of grants classified under D07B (Ropes OR Cables IN General). By volume, Hongduk sits between Holster Fashion Pty Ltd. and Horng Lai Industrial Co., Ltd..

Hongduk's three-year grant acceleration

Hongduk Industrial Co., Ltd. shows 3 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.
