What this shows Dai-ichi's Innovation Score is 38.4/100 (top 41% 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 Dai-ichi?

Each dot is one of Dai-ichi’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). Dai-ichi’s own 17.4 claims/patent is ABOVE the 9.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Dai-ichi's grants concentrate

Dai-ichi Dentsu Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 60% of grants classified under B23P (Metal-working NOT Otherwise Provided FOR; Combined OPERATIONS; Universal Machine Tools). By volume, Dai-ichi sits between D8ai Inc. and Dakota Group S.A.S. DI Zeno Cipriani & C..

Dai-ichi's three-year grant acceleration

Dai-ichi Dentsu Ltd. shows 3 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.
