Does more volume mean deeper claims for Lenntek?
Each dot is one of Lenntek’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). Lenntek’s own 3.8 claims/patent is at or below the 14.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
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.
