Portfolio overview

Aquarius Engines (A.M.) Ltd. has been granted 17 US utility patents between 2017 and 2023, placing Aquarius Engines (A.M.) Ltd. at rank #16,604 across all assignees tracked by PlainPatent. This portfolio spans 10 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.4 claims per patent with primary concentration in F01B (MACHINES OR ENGINES, IN GENERAL OR OF POSITIVE-DISPLACEMENT TYPE, e.g. STEAM ENGINES). As a Foreign Corporation, Aquarius Engines (A.M.) Ltd. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 37.2/100 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 9 grants, compared with 8 in the 2015–2019 window — a +13% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. The Foreign 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. Aquarius Engines (A.M.) Ltd.'s 17.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 10 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Aquarius Engines (A.M.) Ltd. against peers pursuing similar technology classes.
