Portfolio overview
Plainsman MFG. Inc. has been granted 7 US utility patents between 2015 and 2024, placing Plainsman MFG. Inc. at rank #36,912 across all assignees tracked by PlainPatent. This portfolio spans 3 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.1 claims per patent with primary concentration in E21B (EARTH OR ROCK DRILLING; OBTAINING OIL, GAS, WATER, SOLUBLE OR MELTABLE MATERIALS OR A SLURRY OF MINERALS FROM WELLS). As a Foreign Corporation, Plainsman MFG. Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Plainsman sits between Pintail Power Llc (7 patents, rank #36,908) and Plumis Ltd (7 patents, rank #36,916) - the closest US assignees by grant volume. The composite Innovation Score of 41.8/100 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 3 in the 2015–2019 window, a +33% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. The Foreign 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. Plainsman MFG. Inc.'s 14.1 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while specialization in 3 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Plainsman MFG. Inc. against peers pursuing similar technology classes.
