Each dot is one of South-tek’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). South-tek’s own 14.7 claims/patent is ABOVE the 12.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where South-tek's grants concentrate

South-tek Systems, LLC is a focused PatentsView assignee: 8 CPC subclasses with 100% of grants classified under A62C (Fire-fighting). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2016. By volume, South-tek sits between Sortech AG and Sparkle CS Ltd.

South-tek's three-year grant acceleration

South-tek Systems, LLC 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.
