What this shows Quanta's Innovation Score is 38.7/100 (top 40% 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 18.6 claims/patent is ABOVE the 12.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Quanta's grants concentrate

Quanta Dialysis Technologies Limited is a focused PatentsView assignee: 9 CPC subclasses with 73.9% 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 2019 (5 grants) versus a trough of 1 in 2017. By volume, Quanta sits between Power Box AG and Rattunde AG.

Quanta's three-year grant acceleration

Quanta Dialysis Technologies Limited shows 8 grants in 2022–2024 against only 9 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.
