What this shows Amberstone's Innovation Score is 28.9/100 (29th 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 Amberstone?

Each dot is one of Amberstone’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). Amberstone’s own 18.6 claims/patent is ABOVE the 10.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Amberstone's grants concentrate

Amberstone Biosciences, Inc. is a focused PatentsView assignee: 7 CPC subclasses with 80% of grants classified under B01L (Chemical OR Physical Laboratory Apparatus FOR General USE). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2020. By volume, Amberstone sits between Amag Pharmaceuticals, Inc. and Amei Technologies, Inc..

Amberstone's three-year grant acceleration

Amberstone Biosciences, 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.
