USPTO PatentsView assignee record - 9 granted patents across 9 technology areas, active 2018–2023. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: A47L (DOMESTIC WASHING OR CLEANING ; SUCTION CLEANERS IN GENERAL).
The verdict
Rexair holds 9 US patents across 9 technology areas, rank #29,883 of 50,000 tracked assignees.
Rexair Llc has been granted 9 US utility patents between 2018 and 2023, placing Rexair Llc at rank #29,883 across all assignees tracked by PlainPatent. This portfolio spans 9 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.6 claims per patent with primary concentration in A47L (DOMESTIC WASHING OR CLEANING ; SUCTION CLEANERS IN GENERAL). As a US Corporation, Rexair Llc is one of the more focused assignees in the PatentsView dataset. By volume, Rexair sits between Research Center FOR Eco-environmental Scinces, Chinese Academy OF Sciences (9 patents, rank #29,879) and ROAL OY (9 patents, rank #29,887) - the closest US assignees by grant volume. The composite Innovation Score of 45.5/100 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 8 grants, compared with 1 in the 2015–2019 window, a +700% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Rexair Llc's 11.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 9 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Rexair Llc against peers pursuing similar technology classes.

How to use this portfolio
Rexair's 9 grants land it in the top 23% 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.
