What this shows Tristar's Innovation Score is 25.1/100 (16th 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 Tristar?

Each dot is one of Tristar’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). Tristar’s own 2.3 claims/patent is at or below the 15.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Tristar's grants concentrate

Tristar Products, Inc. is a focused PatentsView assignee: 4 CPC subclasses with 3.3% of grants classified under A41C (CORSETS; Brassieres). Peak complete grant year is 2018 (49 grants) versus a trough of 1 in 2015. By volume, Tristar sits between Santen Pharmaceutical Co., Ltd. and BGC Partners, Inc..

Tristar's three-year grant acceleration

Tristar Products, Inc. shows 1 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.
