Portfolio overview

Flow International Corporation has been granted 37 US utility patents between 2015 and 2025, placing Flow International Corporation at rank #8,590 across all assignees tracked by PlainPatent. This portfolio spans 24 distinct Cooperative Patent Classification (CPC) subclasses, averaging 23.1 claims per patent with primary concentration in B24C (ABRASIVE OR RELATED BLASTING WITH PARTICULATE MATERIAL). As a US Corporation, Flow International Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Flow sits between Fortemedia, Inc. (37 patents, rank #8,586) and Green Solution Technology Co., Ltd. (37 patents, rank #8,594) - the closest US assignees by grant volume. The composite Innovation Score of 52.0/100 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 18 grants, compared with 19 in the 2015–2019 window, a -5% 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. Flow International Corporation's 23.1 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while a multi-domain presence across 24 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Flow International Corporation 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.
