Where Crage's grants concentrate

Crage Medical Co., Limited is a focused PatentsView assignee: 7 CPC subclasses with 100% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2022 (7 grants) versus a trough of 1 in 2023. By volume, Crage sits between Cormetrics LLC and CSI Cells Co., Ltd..

Crage's three-year grant acceleration

Crage Medical Co., Limited shows 11 grants in 2022–2024 against only 0 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.
