What this shows Toyoda's Innovation Score is 51.2/100 (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 Toyoda?

Each dot is one of Toyoda’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). Toyoda’s own 6.8 claims/patent is at or below the 10.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

How Toyoda's grant cadence moved

Between 2020–2024, Toyoda Iron Works Co., Ltd. received 28 grants versus 63 in 2015–2019 (-56% equal-window velocity, below median growth). Across complete PatentsView years, output peaked in 2017 at 19 grants and bottomed in 2021 at 4. Lead class G05G accounts for 36.1% of the portfolio across 57 subclasses. Volume neighbours: Sirius XM Radio Inc. (#3,751) and Universite Paul SABATIER—TOULOUSE III (#3,759).

Toyoda's three-year grant acceleration

Toyoda Iron Works Co., Ltd. shows 18 grants in 2022–2024 against only 19 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.
