What this shows Topre's Innovation Score is 31.2/100 (37th 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 Topre?

Each dot is one of Topre’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). Topre’s own 6.6 claims/patent is at or below the 9.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Topre's grants concentrate

Topre Corporation is a focused PatentsView assignee: 16 CPC subclasses with 50% of grants classified under B21D (Working OR Processing OF Sheet Metal OR Metal Tubes, Rods OR Profiles Without Essentially Removing MATERIAL; Punching Metal). Peak complete grant year is 2015 (4 grants) versus a trough of 1 in 2018. By volume, Topre sits between Tokyo Cosmos Electric Co., Ltd. and Transtector Systems, Inc..

Topre's three-year grant acceleration

Topre Corporation 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.
