What this shows Kantas's Innovation Score is 28.5/100 (27th 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 Kantas?

Each dot is one of Kantas’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). Kantas’s own 7.6 claims/patent is at or below the 11.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Kantas's grants concentrate

Kantas Products Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 18.2% of grants classified under B25B (Tools OR Bench Devices NOT Otherwise Provided FOR, FOR Fastening, Connecting, Disengaging OR Holding). Peak complete grant year is 2018 (4 grants) versus a trough of 1 in 2015. By volume, Kantas sits between K. Mizra LLC and KBR Wyle Services, LLC.

Kantas's three-year grant acceleration

Kantas Products Co., Ltd. shows 2 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.
