What this shows Quality's Innovation Score is 24.1/100 (14th percentile 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 Quality?

Each dot is one of Quality’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). Quality’s own 8.6 claims/patent is at or below the 16.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Quality's grants concentrate

Quality Aspirators, Inc. is a focused PatentsView assignee: 3 CPC subclasses with 40% of grants classified under G02B (Optical Elements, Systems OR Apparatus). By volume, Quality sits between Quadex Pharmaceuticals, LLC and Quatius Limited.

Quality's three-year grant acceleration

Quality Aspirators, Inc. shows 1 grants in 2022–2024 against only 1 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.
