What this shows Fuso's Innovation Score is 38.5/100 (top 40% 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 Fuso?

Each dot is one of Fuso’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). Fuso’s own 7.8 claims/patent is at or below the 10.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Fuso's grants concentrate

Fuso Chemical Co., Ltd. is a focused PatentsView assignee: 12 CPC subclasses with 90% of grants classified under C01B (Non-metallic ELEMENTS; Compounds THEREOF; ; Metalloids OR Compounds Thereof NOT Covered BY Subclass C01c). By volume, Fuso sits between Fujidenolo Co., Ltd. and Feellife Health Inc..

Fuso's three-year grant acceleration

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