What this shows Asahi's Innovation Score is 50.8/100 (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 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 15.3 claims/patent is ABOVE the 11.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Asahi's grants concentrate

Asahi Rubber Inc. is a focused PatentsView assignee: 37 CPC subclasses with 55.6% of grants classified under H10H (Inorganic Light-emitting Semiconductor Devices Having Potential Barriers). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2016. By volume, Asahi sits between Apex Biotechnology Corp. and Audio Pixels Ltd..

Asahi's three-year grant acceleration

Asahi Rubber Inc. shows 6 grants in 2022–2024 against only 4 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.
