What this shows Test's Innovation Score is 25.7/100 (18th 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 Test?

Each dot is one of Test’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). Test’s own 4.8 claims/patent is at or below the 16.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Test's grants concentrate

Test Rite International Co., Ltd. is a focused PatentsView assignee: 14 CPC subclasses with 22.2% of grants classified under H05B (Electric HEATING; Electric Light Sources NOT Otherwise Provided FOR; Circuit Arrangements FOR Electric Light Sources, IN General). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2016. By volume, Test sits between TeneoBio, Inc. and The Diablo Canyon Collective LLC.

Test's three-year grant acceleration

Test Rite International Co., Ltd. shows 1 grants in 2022–2024 against only 4 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.
