What this shows Toyo's Innovation Score is 45.6/100 (top 23% 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 Toyo?

Each dot is one of Toyo’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). Toyo’s own 8.3 claims/patent is at or below the 13.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Toyo's grants concentrate

Toyo Denso Kabushiki Kaisha is a focused PatentsView assignee: 31 CPC subclasses with 40.4% of grants classified under H01H (Electric SWITCHES; RELAYS; SELECTORS; Emergency Protective Devices). Peak complete grant year is 2022 (9 grants) versus a trough of 2 in 2015. By volume, Toyo sits between Sub-Zero Group, Inc. and Tesat-Spacecom GmbH & Co. KG.

Toyo's three-year grant acceleration

Toyo Denso Kabushiki Kaisha shows 17 grants in 2022–2024 against only 15 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.
