Where Anhui's grants concentrate

Anhui Meizhi Compressor Co., Ltd. is a focused PatentsView assignee: 13 CPC subclasses with 81.8% of grants classified under F04B (POSITIVE-DISPLACEMENT MACHINES FOR LIQUIDS; PUMPS). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2019. By volume, Anhui sits between Andritz Kuesters Gmbh and AP Specialties.

Anhui's three-year grant acceleration

Anhui Meizhi Compressor Co., Ltd. shows 7 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.
