Does more volume mean deeper claims for Southchip?

Each dot is one of Southchip’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). Southchip’s own 9.6 claims/patent is at or below the 14.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Southchip's grants concentrate

Southchip Semiconductor Technology (Shanghai) Co., Ltd. is a focused PatentsView assignee: 2 CPC subclasses with 100% of grants classified under H02M (Apparatus FOR Conversion Between AC AND AC, Between AC AND DC, OR Between DC AND DC, AND FOR USE With Mains OR Similar Power Supply SYSTEMS; Conversion OF DC OR AC Input Power Into Surge Output POWER;). By volume, Southchip sits between Solvay Advanced Polymers, L.L.C. and Spectrum Health Innovations, LLC.

Southchip's three-year grant acceleration

Southchip Semiconductor Technology (Shanghai) Co., 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.
