What this shows Kyb-ys's Innovation Score is 27.1/100 (22nd 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 Kyb-ys?

Each dot is one of Kyb-ys’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). Kyb-ys’s own 4.2 claims/patent is at or below the 9.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Kyb-ys's grants concentrate

Kyb-ys Co., Ltd. is a focused PatentsView assignee: 14 CPC subclasses with 69.2% of grants classified under F15B (Systems Acting BY Means OF Fluids IN GENERAL; Fluid-pressure Actuators, e.g. SERVOMOTORS; Details OF Fluid-pressure Systems, NOT Otherwise Provided FOR). Peak complete grant year is 2015 (4 grants) versus a trough of 1 in 2017. By volume, Kyb-ys sits between Kromek Group. PLC and Kent Pet Group, Inc..

Kyb-ys's three-year grant acceleration

Kyb-ys Co., Ltd. shows 1 grants in 2022–2024 against only 3 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.
