What this shows Quantum's Innovation Score is 43.3/100 (top 28% 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 Quantum?

Each dot is one of Quantum’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). Quantum’s own 19.4 claims/patent is ABOVE the 14.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Quantum's grants concentrate

Quantum Base Limited is a focused PatentsView assignee: 14 CPC subclasses with 61.5% of grants classified under H04L (Transmission OF Digital Information, e.g. Telegraphic Communication). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2018. By volume, Quantum sits between Qingdao Huatian Hand Truck Co., Ltd. and QuantumZ Inc..

Quantum's three-year grant acceleration

Quantum Base Limited shows 7 grants in 2022–2024 against only 5 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.
