Portfolio overview

Membrane Technology And Research, Inc. has been granted 36 US utility patents between 2015 and 2024, placing Membrane Technology And Research, Inc. at rank #8,874 across all assignees tracked by PlainPatent. This portfolio spans 22 distinct Cooperative Patent Classification (CPC) subclasses, averaging 20.9 claims per patent with primary concentration in B01D (SEPARATION). As a US Corporation, Membrane Technology And Research, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Membrane sits between Malaysian Palm Oil Board (36 patents, rank #8,870) and Multimatic Inc. (36 patents, rank #8,878) - the closest US assignees by grant volume. The composite Innovation Score of 54.9/100 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 7 grants, compared with 29 in the 2015–2019 window, a -76% 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. Membrane Technology And Research, Inc.'s 20.9 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while a multi-domain presence across 22 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Membrane Technology And Research, Inc. against peers pursuing similar technology classes.
