Where Chempartner's grants concentrate

ChemPartner Corporation is a focused PatentsView assignee: 3 CPC subclasses with 100% 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 2021. By volume, Chempartner sits between Ceres Imaging, Inc. and Chr. Hansen Natural Colors A/S.

Chempartner's three-year grant acceleration

ChemPartner Corporation shows 1 grants in 2022–2024 against only 6 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.
