What this shows Unverferth's Innovation Score is 50.3/100 (top 13% 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.

Where Unverferth's grants concentrate

Unverferth Manufacturing Co., Inc. is a focused PatentsView assignee: 25 CPC subclasses with 50.7% of grants classified under A01D (HARVESTING; Mowing). Peak complete grant year is 2017 (11 grants) versus a trough of 2 in 2021. By volume, Unverferth sits between The Vollrath Company, L.L.C. and Yuan MEI Corp..

Unverferth's three-year grant acceleration

Unverferth Manufacturing Co., Inc. shows 18 grants in 2022–2024 against only 15 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.
