Where Vistagen's grants concentrate

Vistagen Therapuetics, Inc. is a focused PatentsView assignee: 8 CPC subclasses with 60% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2017. By volume, Vistagen sits between Vhit S.p.A. and Voxy, Inc.

Vistagen's three-year grant acceleration

Vistagen Therapuetics, Inc. shows 2 grants in 2022–2024 against only 5 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.
