What this shows Fuji's Innovation Score is 33.2/100 (44th 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 Fuji?

Each dot is one of Fuji’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). Fuji’s own 5.4 claims/patent is at or below the 10.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Fuji's grants concentrate

Fuji Kihan Co., Ltd. is a focused PatentsView assignee: 13 CPC subclasses with 85.7% of grants classified under C23C (Coating Metallic MATERIAL; Coating Material With Metallic MATERIAL; Surface Treatment OF Metallic Material BY Diffusion Into THE Surface, BY Chemical Conversion OR SUBSTITUTION; Coating BY Vacuum Evap). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2018. By volume, Fuji sits between FTR Systems Inc. and Fujicco Co., Ltd..

Fuji's three-year grant acceleration

Fuji Kihan Co., Ltd. shows 3 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.
