What this shows Topy's Innovation Score is 32.3/100 (41st 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 Topy?

Each dot is one of Topy’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). Topy’s own 7.1 claims/patent is at or below the 13.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Topy's grants concentrate

Topy Kogyo Kabushiki Kaisha is a focused PatentsView assignee: 22 CPC subclasses with 33.3% of grants classified under B60B (Vehicle Wheels ; CASTORS; Axles FOR Wheels OR CASTORS; Increasing Wheel Adhesion). Peak complete grant year is 2019 (6 grants) versus a trough of 1 in 2020. By volume, Topy sits between TN International and Truxedo, Inc..

Topy's three-year grant acceleration

Topy Kogyo Kabushiki Kaisha shows 1 grants in 2022–2024 against only 9 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.
