Where Meinan's grants concentrate

Meinan Machinery Works, Inc. is a focused PatentsView assignee: 18 CPC subclasses with 50% of grants classified under B27L (Removing Bark OR Vestiges OF Branches ; Splitting WOOD; Manufacture OF Veneer, Wooden Sticks, Wood Shavings, Wood Fibres OR Wood Powder). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2016. By volume, Meinan sits between Medi Manufacturing, Inc. and Mestek Machinery, Inc..

Meinan's three-year grant acceleration

Meinan Machinery Works, Inc. shows 7 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.
