What this shows Fumoto's Innovation Score is 34.1/100 (47th 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 Fumoto?

Each dot is one of Fumoto’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). Fumoto’s own 4.3 claims/patent is at or below the 9.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Fumoto's grants concentrate

Fumoto Giken Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 33.3% of grants classified under F16K (VALVES; TAPS; COCKS; ACTUATING-FLOATS; Devices FOR Venting OR Aerating). Peak complete grant year is 2017 (5 grants) versus a trough of 1 in 2015. By volume, Fumoto sits between Fuji Filter Manufacturing Co., Ltd. and Furui Precise Component (KUNSHAN) Co., Ltd..

Fumoto's three-year grant acceleration

Fumoto Giken 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.
