What this shows Toyo's Innovation Score is 40.1/100 (top 36% 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 9.5 claims/patent is at or below the 14.2 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 Engineering Corporation is a focused PatentsView assignee: 22 CPC subclasses with 44.1% of grants classified under B01D (Separation). Peak complete grant year is 2019 (6 grants) versus a trough of 1 in 2015. By volume, Toyo sits between Taptext LLC and Trifo, Inc..

Toyo's three-year grant acceleration

Toyo Engineering Corporation shows 10 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.
