What this shows Aqua's Innovation Score is 36.8/100 (top 45% 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.

Does more volume mean deeper claims for Aqua?

Each dot is one of Aqua’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Aqua’s own 11.3 claims/patent is at or below the 16.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Aqua's grants concentrate

Aqua Membranes, Inc. is a focused PatentsView assignee: 4 CPC subclasses with 100% of grants classified under B01D (Separation). Peak complete grant year is 2023 (5 grants) versus a trough of 1 in 2019. By volume, Aqua sits between Antaya Technologies Corporation and Asco, L.P..

Aqua's three-year grant acceleration

Aqua Membranes, Inc. shows 8 grants in 2022–2024 against only 4 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.
