Where Histogen's grants concentrate

Histogen, Inc. is a focused PatentsView assignee: 8 CPC subclasses with 75% 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 2016 (2 grants) versus a trough of 1 in 2015. By volume, Histogen sits between High Spot Health Technology Co., Ltd. and Homemation, Inc..

Histogen's three-year grant acceleration

Histogen, Inc. shows 3 grants in 2022–2024 against only 1 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.
