What this shows Tosho's Innovation Score is 34.1/100 (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 Tosho?

Each dot is one of Tosho’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). Tosho’s own 12.6 claims/patent is at or below the 17.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Tosho's grants concentrate

Tosho, Inc. is a focused PatentsView assignee: 12 CPC subclasses with 78.9% of grants classified under A61J (Containers Specially Adapted FOR Medical OR Pharmaceutical PURPOSES; Devices OR Methods Specially Adapted FOR Bringing Pharmaceutical Products Into Particular Physical OR Administering FORMS; Devices ). Peak complete grant year is 2015 (4 grants) versus a trough of 1 in 2017. By volume, Tosho sits between Tianjin Polytechnic University and Tri-state Environmental, LLC.

Tosho's three-year grant acceleration

Tosho, Inc. shows 3 grants in 2022–2024 against only 5 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.
