What this shows Toda's Innovation Score is 47.2/100 (top 19% 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.

Where Toda's grants concentrate

Toda Kogyo Corp. is a focused PatentsView assignee: 44 CPC subclasses with 53.9% of grants classified under C01P (Indexing Scheme Relating TO Structural AND Physical Aspects OF Solid Inorganic Compounds). Peak complete grant year is 2016 (19 grants) versus a trough of 2 in 2022. By volume, Toda sits between Smart Wires Inc. and Arthrosurface Incorporated.

Toda's three-year grant acceleration

Toda Kogyo Corp. shows 10 grants in 2022–2024 against only 16 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.
