Where Northann's grants concentrate
Northann Building Solutions LLC is a focused PatentsView assignee: 7 CPC subclasses with 83.3% of grants classified under E04F (Finishing Work ON Buildings, e.g. Stairs, Floors). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2021. By volume, Northann sits between Normark Innovations, Inc. and Novae.
Northann's three-year grant acceleration
Northann Building Solutions LLC shows 5 grants in 2022–2024 against only 1 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.
