Portfolio overview
Nautilus Engineering, Llc has been granted 6 US utility patents between 2018 and 2023, placing Nautilus Engineering, Llc at rank #41,826 across all assignees tracked by PlainPatent. This portfolio spans 7 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.2 claims per patent with primary concentration in F02B (INTERNAL-COMBUSTION PISTON ENGINES; COMBUSTION ENGINES IN GENERAL). As a US Federal Government, Nautilus Engineering, Llc is one of the more focused assignees in the PatentsView dataset. By volume, Nautilus sits between National Federation OF Agricultural Cooperative Associations (6 patents, rank #41,822) and NCI Group, Inc. (6 patents, rank #41,830) - the closest US assignees by grant volume. The composite Innovation Score of 28.6/100 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 5 grants, compared with 1 in the 2015–2019 window, a +400% 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. Nautilus Engineering, Llc's 18.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 7 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Nautilus Engineering, Llc against peers pursuing similar technology classes.
