What this shows Meinan's Innovation Score is 47.0/100 (top 19% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Meinan?

Each dot is one of Meinan’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Meinan’s own 11.9 claims/patent is at or below the 15.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

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.
