What this shows Aquarius's Innovation Score is 37.2/100 (top 44% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Where Aquarius's grants concentrate

Aquarius Engines (A.M.) Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 94.1% of grants classified under F01B (Machines OR Engines, IN General OR OF Positive-displacement Type, e.g. Steam Engines). Peak complete grant year is 2018 (4 grants) versus a trough of 1 in 2020. By volume, Aquarius sits between AnDAPT, Inc. and Ausco Products, Inc.

Aquarius's three-year grant acceleration

Aquarius Engines (A.M.) Ltd. shows 5 grants in 2022–2024 against only 6 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
