Does more volume mean deeper claims for Southeastern?
Each dot is one of Southeastern’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). Southeastern’s own 13.5 claims/patent is ABOVE the 12.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Southeastern's grants concentrate
Southeastern Metals Manufacturing Co. Inc. is a focused PatentsView assignee: 2 CPC subclasses with 83.3% of grants classified under E04D (Roof COVERINGS; SKY-LIGHTS; GUTTERS; Roof-working Tools). By volume, Southeastern sits between Sotax Corporation and Sparrow Co., Ltd.
Southeastern's three-year grant acceleration
Southeastern Metals Manufacturing Co. Inc. shows 1 grants in 2022–2024 against only 2 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.
