Does more volume mean deeper claims for Bullfrog?

Each dot is one of Bullfrog’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). Bullfrog’s own 15.6 claims/patent is at or below the 18.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Bullfrog's grants concentrate

Bullfrog International, LC is a focused PatentsView assignee: 26 CPC subclasses with 69.2% of grants classified under A61H (Physical Therapy Apparatus, e.g. Devices FOR Locating OR Stimulating Reflex Points IN THE BODY; Artificial RESPIRATION; MASSAGE; Bathing Devices FOR Special Therapeutic OR Hygienic Purposes OR Specifi). Peak complete grant year is 2023 (8 grants) versus a trough of 1 in 2020. By volume, Bullfrog sits between Black Donuts Engineering OY and Bio-Rad Europe GmbH.

Bullfrog's three-year grant acceleration

Bullfrog International, LC shows 11 grants in 2022–2024 against only 7 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.
