Portfolio overview

Energy Recovery, Inc. has been granted 65 US utility patents between 2016 and 2025, placing Energy Recovery, Inc. at rank #5,277 across all assignees tracked by PlainPatent. This portfolio spans 29 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.9 claims per patent with primary concentration in F04F (PUMPING OF FLUID BY DIRECT CONTACT OF ANOTHER FLUID OR BY USING INERTIA OF FLUID TO BE PUMPED ; SIPHONS). As a US Corporation, Energy Recovery, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Energy sits between DRS Network & Imaging Systems, Llc (65 patents, rank #5,273) and Foxlink Image Technology Co., Ltd. (65 patents, rank #5,281) - the closest US assignees by grant volume. The composite Innovation Score of 49.1/100 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 36 grants, compared with 29 in the 2015–2019 window, a +24% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Energy Recovery, Inc.'s 16.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 29 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Energy Recovery, Inc. 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.
