What this shows Doosan's Innovation Score is 72.1/100 (top 1% 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 16.0 claims/patent is ABOVE the 15.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

How Doosan's grant cadence moved

Grant history spans 2022–2025. Across complete PatentsView years, output peaked in 2023 at 67 grants and bottomed in 2022 at 9. Lead class F05D accounts for 47.5% of the portfolio across 70 subclasses. Volume neighbours: Yahoo Ad Tech LLC (#2,468) and PlusAI, Inc. (#2,476).

Doosan's three-year grant acceleration

Doosan Enerbility Co., Ltd. shows 121 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.
