What this shows Asahi's Innovation Score is 44.0/100 (top 27% 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 Asahi?

Each dot is one of Asahi’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). Asahi’s own 12.3 claims/patent is at or below the 17.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Asahi's grants concentrate

Asahi Kasei Construction Materials Corporation is a focused PatentsView assignee: 16 CPC subclasses with 69.2% of grants classified under C08J (WORKING-UP; General Processes OF COMPOUNDING; After-treatment NOT Covered BY Subclasses C08b, C08c, C08f, C08g or C08h). Peak complete grant year is 2018 (4 grants) versus a trough of 1 in 2015. By volume, Asahi sits between Aqua Security Software, Ltd. and AstraZeneca Pharmaceuticals LP.

Asahi's three-year grant acceleration

Asahi Kasei Construction Materials Corporation shows 4 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.
