What this shows Doosan's Innovation Score is 46.7/100 (top 20% 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 Doosan?

Each dot is one of Doosan’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). Doosan’s own 5.7 claims/patent is at or below the 14.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Doosan's grants concentrate

Doosan Industrial Vehicle Co., Ltd. is a focused PatentsView assignee: 18 CPC subclasses with 30% of grants classified under B66F (Hoisting, Lifting, Hauling OR Pushing, NOT Otherwise Provided FOR, e.g. Devices Which Apply A Lifting OR Pushing Force Directly TO THE Surface OF A Load). Peak complete grant year is 2022 (6 grants) versus a trough of 4 in 2023. By volume, Doosan sits between Dole Fresh Vegetables, Inc. and DRB Industrial Co., Ltd..

Doosan's three-year grant acceleration

Doosan Industrial Vehicle Co., Ltd. shows 10 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.
