What this shows Lenntek's Innovation Score is 20.0/100 (6th percentile 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 Lenntek's grants concentrate

Lenntek Corporation is a focused PatentsView assignee: 4 CPC subclasses with 20% of grants classified under F04B (Positive-displacement Machines FOR LIQUIDS; Pumps). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2020. By volume, Lenntek sits between Legacy Custom Products, Inc. and Let's Gel Incorporated.

Lenntek's three-year grant acceleration

Lenntek Corporation shows 2 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.
