What this shows Toyo's Innovation Score is 50.2/100 (top 13% 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.

How Toyo's grant cadence moved

Between 2020–2024, Toyo Aluminium Kabushiki Kaisha received 16 grants versus 32 in 2015–2019 (-50% equal-window velocity, below median growth). Across complete PatentsView years, output peaked in 2015 at 8 grants and bottomed in 2022 at 1. Lead class Y02E accounts for 25% of the portfolio across 58 subclasses. Volume neighbours: Sun Hydraulics, LLC (#6,487) and The University of Nottingham (#6,495).

Toyo's three-year grant acceleration

Toyo Aluminium Kabushiki Kaisha shows 12 grants in 2022–2024 against only 12 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.
