What this shows Kanefusa's Innovation Score is 28.2/100 (26th 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 Kanefusa?

Each dot is one of Kanefusa’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). Kanefusa’s own 11.8 claims/patent is ABOVE the 8.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Kanefusa's grants concentrate

Kanefusa Kabushiki Kaisha is a focused PatentsView assignee: 11 CPC subclasses with 54.5% of grants classified under B23D (PLANING; SLOTTING; SHEARING; BROACHING; SAWING; FILING; SCRAPING; Like Operations FOR Working Metal BY Removing Material, NOT Otherwise Provided FOR). Peak complete grant year is 2020 (4 grants) versus a trough of 1 in 2018. By volume, Kanefusa sits between Jupiter Research, LLC and KBK Industries, LLC.

Kanefusa's three-year grant acceleration

Kanefusa Kabushiki Kaisha shows 1 grants in 2022–2024 against only 8 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.
