What this shows Quanten's Innovation Score is 31.5/100 (38th 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 Quanten?

Each dot is one of Quanten’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). Quanten’s own 17.2 claims/patent is ABOVE the 9.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Quanten's grants concentrate

Quanten Technologies Limited is a focused PatentsView assignee: 8 CPC subclasses with 57.1% of grants classified under H02P (Control OR Regulation OF Electric Motors, Electric Generators OR Dynamo-electric CONVERTERS; Controlling Transformers, Reactors OR Choke Coils). Peak complete grant year is 2020 (5 grants) versus a trough of 1 in 2019. By volume, Quanten sits between Qingdao Richriver Electrics Co., Ltd. and R&L Marketing & Sales, Inc..

Quanten's three-year grant acceleration

Quanten Technologies Limited shows 3 grants in 2022–2024 against only 11 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.
