The verdict
SPF holds 11 US patents across 8 technology areas, rank #25,181 of 50,000 tracked assignees.
SPF Technologies Llc has been granted 11 US utility patents between 2016 and 2025, placing SPF Technologies Llc at rank #25,181 across all assignees tracked by PlainPatent. This portfolio spans 8 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.3 claims per patent with primary concentration in B01D (SEPARATION). As a US Corporation, SPF Technologies Llc is one of the more focused assignees in the PatentsView dataset. By volume, SPF sits between Sondex Wireline Limited (11 patents, rank #25,177) and SSW Advanced Technologies, Llc (11 patents, rank #25,185) - the closest US assignees by grant volume. The composite Innovation Score of 41.3/100 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 6 grants, compared with 5 in the 2015–2019 window, a +20% 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. SPF Technologies Llc's 19.3 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 SPF Technologies Llc against peers pursuing similar technology classes.

How to use this portfolio
SPF's 11 grants land it in the top 34% 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.
