Portfolio overview

S.p.m. Flow Control, Inc. has been granted 75 US utility patents between 2015 and 2021, placing S.p.m. Flow Control, Inc. at rank #4,685 across all assignees tracked by PlainPatent. This portfolio spans 26 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.4 claims per patent with primary concentration in F04B (POSITIVE-DISPLACEMENT MACHINES FOR LIQUIDS; PUMPS). As a US Corporation, S.p.m. Flow Control, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, S.p.m. sits between Pouch Pac Innovations, Llc (75 patents, rank #4,681) and Sparkcognition, Inc (75 patents, rank #4,689) - the closest US assignees by grant volume. The composite Innovation Score of 42.8/100 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 21 grants, compared with 54 in the 2015–2019 window, a -61% 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. S.p.m. Flow Control, Inc.'s 16.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 26 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark S.p.m. Flow Control, Inc. against peers pursuing similar technology classes.
