What this shows Toshiba's Innovation Score is 34.3/100 (47th 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 7.9 claims/patent is at or below the 11.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Toshiba's grants concentrate

Toshiba Plant Systems & Services Corporation is a focused PatentsView assignee: 17 CPC subclasses with 30% of grants classified under F01K (Steam Engine PLANTS; Steam ACCUMULATORS; Engine Plants NOT Otherwise Provided FOR; Engines Using Special Working Fluids OR Cycles). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2015. By volume, Toshiba sits between TLX Technologies, LLC and Toyo Corporation.

Toshiba's three-year grant acceleration

Toshiba Plant Systems & Services Corporation shows 3 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.
