Does more volume mean deeper claims for Brushtech?

Each dot is one of Brushtech’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). Brushtech’s own 5.7 claims/patent is at or below the 17.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Brushtech's grants concentrate

Brushtech, Inc. is a focused PatentsView assignee: 4 CPC subclasses with 33.3% of grants classified under A46D (Manufacture OF Brushes). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2015. By volume, Brushtech sits between Brainium Studios LLC and By Quest LLC.

Brushtech's three-year grant acceleration

Brushtech, Inc. shows 1 grants in 2022–2024 against only 8 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.
