What this shows Doosan's Innovation Score is 62.3/100 (top 2% 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 18.7 claims/patent is ABOVE the 15.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Doosan's grants concentrate

Doosan Bobcat North America, Inc. is a focused PatentsView assignee: 28 CPC subclasses with 77.1% of grants classified under E02F (DREDGING; Soil-shifting). Peak complete grant year is 2024 (13 grants) versus a trough of 2 in 2023. By volume, Doosan sits between DCNS and Eutelsat SA.

Doosan's three-year grant acceleration

Doosan Bobcat North America, Inc. shows 15 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.
