Portfolio overview

Multipure International has been granted 9 US utility patents between 2017 and 2023, placing Multipure International at rank #29,503 across all assignees tracked by PlainPatent. This portfolio spans 16 distinct Cooperative Patent Classification (CPC) subclasses, averaging 20.7 claims per patent with primary concentration in C02F (TREATMENT OF WATER, WASTE WATER, SEWAGE, OR SLUDGE). As a US Corporation, Multipure International is one of the more focused assignees in the PatentsView dataset. By volume, Multipure sits between Motion Control, Inc. (9 patents, rank #29,499) and Nabrawind Technologies, SL (9 patents, rank #29,507) - the closest US assignees by grant volume. The composite Innovation Score of 41.2/100 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 5 in the 2015–2019 window, a -20% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Multipure International's 20.7 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 16 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Multipure International against peers pursuing similar technology classes.

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.
