What this shows Fuji's Innovation Score is 24.1/100 (14th 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.

Where Fuji's grants concentrate

Fuji Hollow Valve Inc. is a focused PatentsView assignee: 10 CPC subclasses with 100% of grants classified under F01L (Cyclically Operating Valves FOR Machines OR Engines). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2017. By volume, Fuji sits between FTI Brands LLC and Fujitsu Interconnect Technologies Limited.

Fuji's three-year grant acceleration

Fuji Hollow Valve Inc. 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.
