What this shows Doosan's Innovation Score is 49.6/100 (top 14% 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 32.7 claims/patent is ABOVE the 11.7 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 GridTech, Inc. is a focused PatentsView assignee: 5 CPC subclasses with 100% of grants classified under H02J (Circuit Arrangements OR Systems FOR Supplying OR Distributing Electric POWER; Systems FOR Storing Electric Energy). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2017. By volume, Doosan sits between Dongguan Super Electric Technology Co., Ltd and Dow Quimica Mexicana S.A.de C.V..

Doosan's three-year grant acceleration

Doosan GridTech, Inc. shows 4 grants in 2022–2024 against only 1 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.
