What this shows Daihachi's Innovation Score is 51.2/100 (top 12% 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 Daihachi?

Each dot is one of Daihachi’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). Daihachi’s own 10.7 claims/patent is at or below the 18.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Daihachi's grants concentrate

Daihachi Chemical Industry Co., Ltd. is a focused PatentsView assignee: 21 CPC subclasses with 72.7% of grants classified under C08K (Use of inorganic or non-macromolecular organic substances as compounding ingredients). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2019. By volume, Daihachi sits between Cyborg Inc. and Deepintent, Inc..

Daihachi's three-year grant acceleration

Daihachi Chemical Industry Co., Ltd. shows 5 grants in 2022–2024 against only 1 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.
