What this shows Fine's Innovation Score is 40.1/100 (top 36% 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 Fine?

Each dot is one of Fine’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). Fine’s own 6.6 claims/patent is at or below the 9.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Fine's grants concentrate

Fine Sinter Co., Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 58.3% of grants classified under B22F (Working Metallic POWDER; Manufacture OF Articles From Metallic POWDER; Making Metallic Powder ; Apparatus OR Devices Specially Adapted FOR Metallic Powder). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2015. By volume, Fine sits between Fiery, LLC and Fives Machining Systems, Inc..

Fine's three-year grant acceleration

Fine Sinter Co., Ltd. shows 5 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.
