What this shows Tomey's Innovation Score is 37.8/100 (top 42% 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 Tomey?

Each dot is one of Tomey’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). Tomey’s own 9.5 claims/patent is at or below the 16.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Tomey's grants concentrate

Tomey Corporation is a focused PatentsView assignee: 13 CPC subclasses with 97.8% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2017 (9 grants) versus a trough of 1 in 2020. By volume, Tomey sits between TDW Delaware, Inc. and UNIVERSITÉ Libre DE Bruxelles.

Tomey's three-year grant acceleration

Tomey Corporation shows 10 grants in 2022–2024 against only 11 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.
