USPTO PatentsView assignee record - 6 granted patents across 5 technology areas, active 2016–2022. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: F04B (POSITIVE-DISPLACEMENT MACHINES FOR LIQUIDS; PUMPS).
The verdict
Zahroof holds 6 US patents across 5 technology areas, rank #44,204 of 50,000 tracked assignees.
Zahroof Valves Inc. has been granted 6 US utility patents between 2016 and 2022, placing Zahroof Valves Inc. at rank #44,204 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 30.3 claims per patent with primary concentration in F04B (POSITIVE-DISPLACEMENT MACHINES FOR LIQUIDS; PUMPS). As a US Corporation, Zahroof Valves Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Zahroof sits between Zrodelta, Llc (6 patents, rank #44,200) and Zedel S.a. (6 patents, rank #44,208) - the closest US assignees by grant volume. The composite Innovation Score of 33.0/100 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 3 grants, compared with 3 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. Zahroof Valves Inc.'s 30.3 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 5 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Zahroof Valves Inc. against peers pursuing similar technology classes.

How to use this portfolio
Zahroof's 6 grants land it in the top 57% by Innovation Score, but volume alone doesn't tell you where the strength sits.
Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
