What this shows Asterias's Innovation Score is 29.8/100 (32nd 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 Asterias?

Each dot is one of Asterias’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). Asterias’s own 11.6 claims/patent is at or below the 15.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Asterias's grants concentrate

Asterias Biotherapeutics, Inc. is a focused PatentsView assignee: 8 CPC subclasses with 100% of grants classified under C12N (Microorganisms OR ENZYMES; Compositions THEREOF; Propagating, Preserving, OR Maintaining MICROORGANISMS; Mutation OR Genetic ENGINEERING; Culture Media). Peak complete grant year is 2015 (6 grants) versus a trough of 1 in 2018. By volume, Asterias sits between Aprecia Pharmaceuticals LLC and Active Implants LLC.

Asterias's three-year grant acceleration

Asterias Biotherapeutics, Inc. shows 2 grants in 2022–2024 against only 6 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.
