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.
