What this shows Daiichi's Innovation Score is 53.2/100 (top 9% 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 Daiichi?

Each dot is one of Daiichi’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). Daiichi’s own 9.4 claims/patent is at or below the 12.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Daiichi's grants concentrate

Daiichi Kigenso Kagaku Kogyo Co., Ltd. is a focused PatentsView assignee: 20 CPC subclasses with 79.3% of grants classified under C01P (Indexing Scheme Relating TO Structural AND Physical Aspects OF Solid Inorganic Compounds). Peak complete grant year is 2022 (7 grants) versus a trough of 1 in 2019. By volume, Daiichi sits between Communications Test Design, Inc. and Daechang Seat Co., LTD-Dongtan.

Daiichi's three-year grant acceleration

Daiichi Kigenso Kagaku Kogyo Co., Ltd. shows 13 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.
