What this shows Toshiba's Innovation Score is 28.4/100 (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 Toshiba?

Each dot is one of Toshiba’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). Toshiba’s own 10.6 claims/patent is ABOVE the 7.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Toshiba's grants concentrate

Toshiba Elevator Kabushiki Kaisha is a focused PatentsView assignee: 7 CPC subclasses with 92.9% of grants classified under B66B (ELEVATORS; Escalators OR Moving Walkways). Peak complete grant year is 2016 (3 grants) versus a trough of 1 in 2015. By volume, Toshiba sits between Tokyo University OF Science Educational Foundation Administrative Organization and Trelleborg Wheel Systems Italia S.P.A..

Toshiba's three-year grant acceleration

Toshiba Elevator Kabushiki Kaisha shows 3 grants in 2022–2024 against only 6 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.
