What this shows Toyo's Innovation Score is 40.4/100 (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 12.6 claims/patent is ABOVE the 11.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Toyo's grants concentrate

Toyo Gosei Co., Ltd. is a focused PatentsView assignee: 29 CPC subclasses with 55% of grants classified under G03F (Photomechanical Production OF Textured OR Patterned Surfaces, e.g. FOR Printing, FOR Processing OF Semiconductor DEVICES; Materials THEREFOR; Originals THEREFOR; Apparatus Specially Adapted THEREFOR;). Peak complete grant year is 2017 (10 grants) versus a trough of 1 in 2022. By volume, Toyo sits between TDA Research, Inc. and Tiger Tool International Incorporated.

Toyo's three-year grant acceleration

Toyo Gosei Co., Ltd. shows 2 grants in 2022–2024 against only 14 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.
