What this shows Aisin's Innovation Score is 42.3/100 (top 31% 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 Aisin?

Each dot is one of Aisin’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). Aisin’s own 7.5 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 Aisin's grants concentrate

Aisin Takaoka Co., Ltd. is a focused PatentsView assignee: 41 CPC subclasses with 17.9% of grants classified under C21D (Modifying THE Physical Structure OF Ferrous METALS; General Devices FOR Heat Treatment OF Ferrous OR Non-ferrous Metals OR ALLOYS; Making Metal Malleable, e.g. BY Decarburisation OR Tempering). Peak complete grant year is 2015 (7 grants) versus a trough of 1 in 2022. By volume, Aisin sits between iOttie Inc. and AYR Ltd..

Aisin's three-year grant acceleration

Aisin Takaoka Co., Ltd. shows 5 grants in 2022–2024 against only 14 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.
