What this shows Biostage's Innovation Score is 34.5/100 (48th 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 Biostage?

Each dot is one of Biostage’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). Biostage’s own 12.7 claims/patent is at or below the 12.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Biostage's grants concentrate

Biostage, Inc. is a focused PatentsView assignee: 8 CPC subclasses with 63.6% of grants classified under C12M (Apparatus FOR Enzymology OR MICROBIOLOGY; Apparatus FOR Culturing Microorganisms FOR Producing Biomass, FOR Growing Cells OR FOR Obtaining Fermentation OR Metabolic Products, i.e. Bioreactors OR Ferme). Peak complete grant year is 2022 (5 grants) versus a trough of 1 in 2020. By volume, Biostage sits between Besing Technology (Shenzhen) Co., Ltd. and Black Gold Coin, Inc..

Biostage's three-year grant acceleration

Biostage, Inc. shows 5 grants in 2022–2024 against only 4 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.
