Peak complete grant year is 2018 (2 grants) versus a trough of 1 in 2020. By volume, Princeton sits between Pride Family Brands, Inc. and Pro-Gard Products LLC.

Princeton's three-year grant acceleration

Princeton Drug 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.
