What this shows Aisin's Innovation Score is 72.2/100 (top 1% 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 9.1 claims/patent is at or below the 17.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

How Aisin's grant cadence moved

Between 2020–2024, Aisin Corporation received 456 grants versus 1 in 2015–2019 (+45500% equal-window velocity, top decile growth). Across complete PatentsView years, output peaked in 2022 at 182 grants and bottomed in 2015 at 1. Lead class H02K accounts for 19.3% of the portfolio across 131 subclasses. Volume neighbours: Gree Holdings, Inc. (#833) and Xiamen Tianma Micro-Electronics Co., Ltd. (#841).

Aisin's three-year grant acceleration

Aisin Corporation shows 447 grants in 2022–2024 against only 9 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.
