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 18.2 claims/patent is ABOVE the 7.8 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 Enerbnlity Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 80% of grants classified under F01D (Non-positive Displacement Machines OR Engines, e.g. Steam Turbines). By volume, Doosan sits between Dongguk University Gyeongju Campus Industry-academy Cooperation Foundation and Doria International Inc.

Doosan's three-year grant acceleration

Doosan Enerbnlity Co., Ltd. shows 5 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.
