Where Acerus's grants concentrate

Acerus Biopharma Inc. is a focused PatentsView assignee: 4 CPC subclasses with 80% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2023 (2 grants) versus a trough of 1 in 2018. By volume, Acerus sits between Accu Target Medipharma (SHANGHAI) Co., Ltd. and ACM Research, Inc..

Acerus's three-year grant acceleration

Acerus Biopharma Inc. shows 2 grants in 2022–2024 against only 2 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.
