Does more volume mean deeper claims for Royal?

Each dot is one of Royal’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). Royal’s own 4.7 claims/patent is at or below the 18.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Royal's grants concentrate

Royal Brush Manufacturing, Inc. is a focused PatentsView assignee: 3 CPC subclasses with 22.2% of grants classified under A46D (Manufacture OF Brushes). Peak complete grant year is 2019 (4 grants) versus a trough of 1 in 2020. By volume, Royal sits between Rosemont Pharmaceuticals Limited and RxANTE, Inc..

Royal's three-year grant acceleration

Royal Brush Manufacturing, 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.
