Portfolio overview

Q.e.d. Environmental Systems, Inc. has been granted 22 US utility patents between 2017 and 2025, placing Q.e.d. Environmental Systems, Inc. at rank #13,636 across all assignees tracked by PlainPatent. This portfolio spans 19 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.6 claims per patent with primary concentration in E21B (EARTH OR ROCK DRILLING; OBTAINING OIL, GAS, WATER, SOLUBLE OR MELTABLE MATERIALS OR A SLURRY OF MINERALS FROM WELLS). As a US Corporation, Q.e.d. Environmental Systems, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Q.e.d. sits between Protiva Biotherapeutics, Inc. (22 patents, rank #13,632) and Quantaed, Llc (22 patents, rank #13,640) - the closest US assignees by grant volume. The composite Innovation Score of 54.0/100 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 12 grants, compared with 10 in the 2015–2019 window, a +20% 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. Q.e.d. Environmental Systems, Inc.'s 16.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 19 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Q.e.d. Environmental Systems, Inc. against peers pursuing similar technology classes.
