Does more volume mean deeper claims for Unverferth?
Each dot is one of Unverferth’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). Unverferth’s own 16.5 claims/patent is ABOVE the 13.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
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.
