Does more volume mean deeper claims for Northann?
Each dot is one of Northann’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). Northann’s own 25.2 claims/patent is ABOVE the 13.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
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.
