What this shows Aurastem's Innovation Score is 34.1/100 (47th 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 Aurastem?

Each dot is one of Aurastem’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). Aurastem’s own 21.6 claims/patent is ABOVE the 14.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Aurastem's grants concentrate

Aurastem LLC is a focused PatentsView assignee: 2 CPC subclasses with 100% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2024. By volume, Aurastem sits between Audioptics Medical Inc. and Auson Pharmaceuticals Inc..

Aurastem's three-year grant acceleration

Aurastem LLC shows 3 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.
