What this shows Dubrosky's Innovation Score is 30.3/100 (34th 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 Dubrosky?

Each dot is one of Dubrosky’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). Dubrosky’s own 9.6 claims/patent is at or below the 19.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Dubrosky's grants concentrate

Dubrosky & Tracy Patent Service Corp. is a focused PatentsView assignee: 8 CPC subclasses with 41.9% of grants classified under A41F (Garment FASTENINGS; Suspenders). Peak complete grant year is 2020 (8 grants) versus a trough of 1 in 2023. By volume, Dubrosky sits between Crystal Lagoons Technologies, Inc. and Emseal Joint Systems, Ltd..

Dubrosky's three-year grant acceleration

Dubrosky & Tracy Patent Service Corp. shows 5 grants in 2022–2024 against only 13 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.
