Does more volume mean deeper claims for Vistagen?
Each dot is one of Vistagen’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). Vistagen’s own 9.3 claims/patent is at or below the 10.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
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.
