Where Lakehead's grants concentrate

Lakehead University is a focused PatentsView assignee: 28 CPC subclasses with 27.3% of grants classified under C01B (NON-METALLIC ELEMENTS; COMPOUNDS THEREOF; ; METALLOIDS OR COMPOUNDS THEREOF NOT COVERED BY SUBCLASS C01C). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2018. By volume, Lakehead sits between L-3 Communications Cincinnati Electronics Corporation and Laurel Machinery Co., Ltd..

Lakehead's three-year grant acceleration

Lakehead University shows 2 grants in 2022–2024 against only 5 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.
