What this shows Quantum's Innovation Score is 50.9/100 (top 12% 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 17.4 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 Silicon Inc. is a focused PatentsView assignee: 11 CPC subclasses with 62.5% of grants classified under H10D (Inorganic Electric Semiconductor Devices). Peak complete grant year is 2023 (3 grants) versus a trough of 1 in 2024. By volume, Quantum sits between Qlight Nanotech Ltd. and Quirky Incorporated.

Quantum's three-year grant acceleration

Quantum Silicon Inc. shows 6 grants in 2022–2024 against only 2 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.
