Where Changhua's grants concentrate

Changhua Christian Medical Foundation Changhua Christian Hospital is a focused PatentsView assignee: 9 CPC subclasses with 33.3% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2023 (2 grants) versus a trough of 1 in 2019. By volume, Changhua sits between CGS Technology, LLC and Charles R. Drew University OF Medicine AND Science.

Changhua's three-year grant acceleration

Changhua Christian Medical Foundation Changhua Christian Hospital shows 4 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.
