What this shows Kone's Innovation Score is 23.2/100 (12th 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 Kone?

Each dot is one of Kone’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). Kone’s own 13.8 claims/patent is ABOVE the 10.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Kone's grants concentrate

Kone Elevators Co. Ltd is a focused PatentsView assignee: 4 CPC subclasses with 100% of grants classified under B66B (ELEVATORS; Escalators OR Moving Walkways). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2019. By volume, Kone sits between Koch Pac-systeme GMBH and Kotobuki Tsushou Co., Ltd..

Kone's three-year grant acceleration

Kone Elevators Co. Ltd shows 1 grants in 2022–2024 against only 4 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.
