Does more volume mean deeper claims for Sophia?

Each dot is one of Sophia’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). Sophia’s own 1.2 claims/patent is at or below the 11.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sophia's grants concentrate

Sophia & William Brands Co. Ltd is a focused PatentsView assignee: 1 CPC subclasses with 2.9% of grants classified under A47B (TABLES; DESKS; Office FURNITURE; CABINETS; DRAWERS; General Details OF Furniture). Peak complete grant year is 2023 (14 grants) versus a trough of 6 in 2024. By volume, Sophia sits between SDG, LLC and Streem, LLC.

Sophia's three-year grant acceleration

Sophia & William Brands Co. Ltd shows 27 grants in 2022–2024 against only 0 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.
