What this shows Toyo's Innovation Score is 28.5/100 (27th percentile 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 4.9 claims/patent is at or below the 11.6 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 Electric MFG. Co., Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 28.6% of grants classified under B60L (Propulsion OF Electrically-propelled Vehicles ; Supplying Electric Power FOR Auxiliary Equipment OF Electrically-propelled Vehicles ; Electrodynamic Brake Systems FOR Vehicles IN General ; Magnetic SU). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2016. By volume, Toyo sits between Torque-tech Precision Co., Ltd. and TPE Midstream LLC.

Toyo's three-year grant acceleration

Toyo Electric MFG. Co., Ltd. shows 1 grants in 2022–2024 against only 1 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.
