Does more volume mean deeper claims for Sandgroup?

Each dot is one of Sandgroup’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). Sandgroup’s own 4.5 claims/patent is at or below the 16.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sandgroup's grants concentrate

Sandgroup International Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 30.8% of grants classified under A63B (Apparatus FOR Physical Training, Gymnastics, Swimming, Climbing, OR FENCING; Ball GAMES; Training Equipment). Peak complete grant year is 2018 (8 grants) versus a trough of 1 in 2019. By volume, Sandgroup sits between Safe Flight Instrument, LLC and Sauce Labs Inc..

Sandgroup's three-year grant acceleration

Sandgroup International Ltd. shows 1 grants in 2022–2024 against only 1 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.
