What this shows Tone's Innovation Score is 31.0/100 (36th 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 Tone?

Each dot is one of Tone’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). Tone’s own 5.0 claims/patent is at or below the 10.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Tone's grants concentrate

Tone Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 66.7% of grants classified under B25B (Tools OR Bench Devices NOT Otherwise Provided FOR, FOR Fastening, Connecting, Disengaging OR Holding). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2016. By volume, Tone sits between Tobesoft Co., Ltd. and TOP Alliance Technology Limited.

Tone's three-year grant acceleration

Tone Co., Ltd. shows 2 grants in 2022–2024 against only 0 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.
