What this shows Shiraishi's Innovation Score is 28.1/100 (26th 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 Shiraishi?

Each dot is one of Shiraishi’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). Shiraishi’s own 5.4 claims/patent is at or below the 7.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Shiraishi's grants concentrate

Shiraishi Kogyo Kaisha, Ltd. is a focused PatentsView assignee: 14 CPC subclasses with 80% of grants classified under C08K (Use of inorganic or non-macromolecular organic substances as compounding ingredients). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2015. By volume, Shiraishi sits between Shenzhen Vmax NEW Energy Co., Ltd. and Sightline Innovation Inc..

Shiraishi's three-year grant acceleration

Shiraishi Kogyo Kaisha, Ltd. shows 3 grants in 2022–2024 against only 6 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.
