Where Anhui's grants concentrate

Anhui University OF Technology is a focused PatentsView assignee: 10 CPC subclasses with 42.9% of grants classified under C23C (Coating Metallic MATERIAL; Coating Material With Metallic MATERIAL; Surface Treatment OF Metallic Material BY Diffusion Into THE Surface, BY Chemical Conversion OR SUBSTITUTION; Coating BY Vacuum Evap). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2021. By volume, Anhui sits between Angelcare USA, LLC and Annai Systems Inc..

Anhui's three-year grant acceleration

Anhui University OF Technology shows 4 grants in 2022–2024 against only 1 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.
