Where Stemina's grants concentrate

Stemina Biomarker Discovery, Inc. is a focused PatentsView assignee: 3 CPC subclasses with 100% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2019 (3 grants) versus a trough of 1 in 2017. By volume, Stemina sits between Steinfurth Mess-Systeme GmbH and Stichting VUmc.

Stemina's three-year grant acceleration

Stemina Biomarker Discovery, 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.
