Where Hanall's grants concentrate

Hanall Biopharma Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 88.9% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2020. By volume, Hanall sits between Halo Trademarks Limited and Hanmi IT Co., Ltd..

Hanall's three-year grant acceleration

Hanall Biopharma Co., Ltd. shows 2 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.
