What this shows Doowon's Innovation Score is 37.4/100 (top 44% 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 Doowon?

Each dot is one of Doowon’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). Doowon’s own 12.8 claims/patent is at or below the 13.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Doowon's grants concentrate

Doowon Climate Control Co., Ltd. is a focused PatentsView assignee: 16 CPC subclasses with 87.5% of grants classified under B60H (Arrangements OF Heating, Cooling, Ventilating OR Other Air-treating Devices Specially Adapted FOR Passenger OR Goods Spaces OF Vehicles). Peak complete grant year is 2020 (4 grants) versus a trough of 1 in 2023. By volume, Doowon sits between Dentsu Inc. and Deeping Source Inc..

Doowon's three-year grant acceleration

Doowon Climate Control Co., Ltd. shows 6 grants in 2022–2024 against only 9 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.
