What this shows Fuji's Innovation Score is 33.4/100 (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 4.8 claims/patent is at or below the 10.9 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 Seiko Co., Ltd. is a focused PatentsView assignee: 25 CPC subclasses with 66.7% of grants classified under B29D (Producing Particular Articles From Plastics OR From Substances IN A Plastic State). Peak complete grant year is 2020 (9 grants) versus a trough of 1 in 2023. By volume, Fuji sits between Fastbrick IP PTY Ltd and Gibson Brands, Inc..

Fuji's three-year grant acceleration

Fuji Seiko Co., Ltd. shows 1 grants in 2022–2024 against only 19 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.
