What this shows Daiwa's Innovation Score is 30.4/100 (34th 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 Daiwa?

Each dot is one of Daiwa’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). Daiwa’s own 6.0 claims/patent is at or below the 17.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Daiwa's grants concentrate

Daiwa Kasei Industry Co., Ltd. is a focused PatentsView assignee: 12 CPC subclasses with 66.7% of grants classified under B60R (Vehicles, Vehicle Fittings, OR Vehicle Parts, NOT Otherwise Provided FOR). Peak complete grant year is 2015 (4 grants) versus a trough of 1 in 2023. By volume, Daiwa sits between CommScope Asia Holdings B.V. and Douyin Vision Co., Ltd..

Daiwa's three-year grant acceleration

Daiwa Kasei Industry Co., Ltd. shows 4 grants in 2022–2024 against only 11 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.
