What this shows DAH's Innovation Score is 27.1/100 (22nd percentile 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 DAH?

Each dot is one of DAH’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). DAH’s own 8.8 claims/patent is at or below the 12.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where DAH's grants concentrate

DAH LIH PUH Co., Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 83.3% of grants classified under A43B (Characteristic Features OF FOOTWEAR; Parts OF Footwear). By volume, DAH sits between Daedong Movel System Co., Ltd. and Dandelion Energy, Inc..

DAH's three-year grant acceleration

DAH LIH PUH Co., Ltd. shows 1 grants in 2022–2024 against only 2 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.
