What this shows Quantum's Innovation Score is 48.2/100 (top 17% 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 14.5 claims/patent is ABOVE the 12.1 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 Surgical is a focused PatentsView assignee: 9 CPC subclasses with 75% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2024 (4 grants) versus a trough of 1 in 2023. By volume, Quantum sits between Qingdao Haigao Design & Manufacturing Co., Ltd. and Qwilt Inc..

Quantum's three-year grant acceleration

Quantum Surgical shows 5 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.
