Portfolio overview
South-tek Systems, Llc has been granted 6 US utility patents between 2016 and 2022, placing South-tek Systems, Llc at rank #42,957 across all assignees tracked by PlainPatent. This portfolio spans 8 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.7 claims per patent with primary concentration in A62C (FIRE-FIGHTING). As a US Corporation, South-tek Systems, Llc is one of the more focused assignees in the PatentsView dataset. By volume, South-tek sits between Sortech Ag (6 patents, rank #42,953) and Sparkle CS Ltd (6 patents, rank #42,961) - the closest US assignees by grant volume. The composite Innovation Score of 32.2/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.
Filing cadence tells the strategic story. Between 2020 and 2025 the company received 2 grants, compared with 4 in the 2015–2019 window, a -50% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The US Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.
Claim depth and technology breadth together indicate competitive posture. South-tek Systems, Llc's 14.7 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 8 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark South-tek Systems, Llc against peers pursuing similar technology classes.
