What this shows DRB's Innovation Score is 26.9/100 (22nd 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 DRB?

Each dot is one of DRB’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). DRB’s own 2.6 claims/patent is at or below the 14.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where DRB's grants concentrate

DRB Industrial Co., Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 20% of grants classified under B62D (Motor VEHICLES; Trailers). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2022. By volume, DRB sits between Doosan Industrial Vehicle Co., Ltd. and DRS Power & Control Technologies, Inc..

DRB's three-year grant acceleration

DRB Industrial Co., Ltd. shows 6 grants in 2022–2024 against only 4 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.
