What this shows Eriez's Innovation Score is 38.0/100 (top 42% 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 Eriez's grants concentrate

Eriez Manufacturing Co. is a focused PatentsView assignee: 12 CPC subclasses with 64.3% of grants classified under B03D (FLOTATION; Differential Sedimentation). Peak complete grant year is 2015 (3 grants) versus a trough of 1 in 2016. By volume, Eriez sits between Emotiv Inc. and Euclid Techlabs, LLC.

Eriez's three-year grant acceleration

Eriez Manufacturing Co. shows 3 grants in 2022–2024 against only 4 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.
