What this shows Toyokoh's Innovation Score is 33.9/100 (46th 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 Toyokoh?

Each dot is one of Toyokoh’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). Toyokoh’s own 20.2 claims/patent is ABOVE the 6.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Toyokoh's grants concentrate

Toyokoh Co., Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 83.3% of grants classified under B23K (Soldering OR UNSOLDERING; WELDING; Cladding OR Plating BY Soldering OR WELDING; Cutting BY Applying Heat Locally, e.g. Flame CUTTING; Working BY Laser Beam). By volume, Toyokoh sits between Torrgas Technology B.V. and Travel Blue Limited.

Toyokoh's three-year grant acceleration

Toyokoh Co., Ltd. shows 1 grants in 2022–2024 against only 2 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.
