Portfolio overview
3EFLOW AB has been granted 9 US utility patents between 2016 and 2021, placing 3EFLOW AB at rank #27,941 across all assignees tracked by PlainPatent. This portfolio spans 8 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.7 claims per patent with primary concentration in E03B (INSTALLATIONS OR METHODS FOR OBTAINING, COLLECTING, OR DISTRIBUTING WATER). As a Foreign Corporation, 3EFLOW AB is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 27.9/100 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 2 in the 2015–2019 window — a +250% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. 3EFLOW AB's 16.7 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 3EFLOW AB against peers pursuing similar technology classes.
