Portfolio overview
Sioux Chief Mfg. Co., Inc. has been granted 8 US utility patents between 2015 and 2025, placing Sioux Chief Mfg. Co., Inc. at rank #33,405 across all assignees tracked by PlainPatent. This portfolio spans 6 distinct Cooperative Patent Classification (CPC) subclasses, averaging 20.0 claims per patent with primary concentration in F16L (PIPES; JOINTS OR FITTINGS FOR PIPES; SUPPORTS FOR PIPES, CABLES OR PROTECTIVE TUBING; MEANS FOR THERMAL INSULATION IN GENERAL). As a US Corporation, Sioux Chief Mfg. Co., Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Sioux sits between Simpson Performance Products, Inc. (8 patents, rank #33,401) and Skan Ag (8 patents, rank #33,409) - the closest US assignees by grant volume. The composite Innovation Score of 31.6/100 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 4 grants, compared with 4 in the 2015–2019 window, a +0% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Sioux Chief Mfg. Co., Inc.'s 20.0 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 6 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Sioux Chief Mfg. Co., Inc. against peers pursuing similar technology classes.
