Does more volume mean deeper claims for Southern?
Each dot is one of Southern’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). Southern’s own 22.5 claims/patent is ABOVE the 16.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Southern's grants concentrate
Southern Mills, Inc. is a focused PatentsView assignee: 15 CPC subclasses with 70.8% of grants classified under D03D (Woven FABRICS; Methods OF WEAVING; Looms). Peak complete grant year is 2019 (4 grants) versus a trough of 1 in 2016. By volume, Southern sits between Shanghai XPT Technology Limited and Strata Products Worldwide, LLC.
Southern's three-year grant acceleration
Southern Mills, Inc. shows 9 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.
