Portfolio overview
Quartus Engineering Incorporated has been granted 9 US utility patents between 2016 and 2025, placing Quartus Engineering Incorporated at rank #29,858 across all assignees tracked by PlainPatent. This portfolio spans 7 distinct Cooperative Patent Classification (CPC) subclasses, averaging 23.3 claims per patent with primary concentration in A61B (DIAGNOSIS; SURGERY; IDENTIFICATION). As a US Federal Government, Quartus Engineering Incorporated is one of the more focused assignees in the PatentsView dataset. By volume, Quartus sits between Quality Craft Industries, Inc. (9 patents, rank #29,854) and Quintel Technology Limited (9 patents, rank #29,862) - the closest US assignees by grant volume. The composite Innovation Score of 51.3/100 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 8 grants, compared with 1 in the 2015–2019 window, a +700% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The US Federal Government 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. Quartus Engineering Incorporated's 23.3 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 7 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Quartus Engineering Incorporated against peers pursuing similar technology classes.
