What this shows Quanta's Innovation Score is 32.6/100 (42nd 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 Quanta?

Each dot is one of Quanta’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). Quanta’s own 16.8 claims/patent is at or below the 19.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Quanta's grants concentrate

Quanta Fluid Solutions Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 77.8% of grants classified under A61M (Devices FOR Introducing Media Into, OR Onto, THE Body ; Devices FOR Transducing Body Media OR FOR Taking Media From THE Body ; Devices FOR Producing OR Ending Sleep OR Stupor). Peak complete grant year is 2015 (3 grants) versus a trough of 1 in 2024. By volume, Quanta sits between Qingdao Vland Biotech Group Co., Ltd and QuadTech, Inc..

Quanta's three-year grant acceleration

Quanta Fluid Solutions Ltd. shows 1 grants in 2022–2024 against only 0 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.
