What this shows Quspin's Innovation Score is 26.2/100 (20th 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 Quspin?

Each dot is one of Quspin’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). Quspin’s own 14.3 claims/patent is ABOVE the 9.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Quspin's grants concentrate

QuSpin Inc. is a focused PatentsView assignee: 6 CPC subclasses with 83.3% of grants classified under G01R (Measuring Electric VARIABLES; Measuring Magnetic Variables). By volume, Quspin sits between Qingdao Genjoy Home Fashion Co., Ltd. and Quantum Information Security, LLC.

Quspin's three-year grant acceleration

QuSpin Inc. shows 1 grants in 2022–2024 against only 3 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.
