What this shows Dai-ichi's Innovation Score is 47.0/100 (top 19% 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 9.6 claims/patent is at or below the 13.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Dai-ichi's grants concentrate

Dai-ichi Kogyo Seiyaku Co., Ltd. is a focused PatentsView assignee: 41 CPC subclasses with 33.3% of grants classified under C08K (Use of inorganic or non-macromolecular organic substances as compounding ingredients). Peak complete grant year is 2016 (10 grants) versus a trough of 2 in 2023. By volume, Dai-ichi sits between Clarkson University and Delta Electronics (Thailand) Public Company Limited.

Dai-ichi's three-year grant acceleration

Dai-ichi Kogyo Seiyaku Co., Ltd. shows 10 grants in 2022–2024 against only 14 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.
