Portfolio overview

EXTERRAN WATER SOLUTIONS ULC has been granted 9 US utility patents between 2015 and 2021, placing EXTERRAN WATER SOLUTIONS ULC at rank #28,666 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.0 claims per patent with primary concentration in B01D (SEPARATION). As a Foreign Corporation, EXTERRAN WATER SOLUTIONS ULC is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 25.8/100 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 1 grants, compared with 8 in the 2015–2019 window — a -87% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The Foreign 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. EXTERRAN WATER SOLUTIONS ULC's 18.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while specialization in 4 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark EXTERRAN WATER SOLUTIONS ULC against peers pursuing similar technology classes.
