Does more volume mean deeper claims for North?
Each dot is one of North’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). North’s own 18.2 claims/patent is ABOVE the 11.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where North's grants concentrate
North American Pipe Corporation is a focused PatentsView assignee: 10 CPC subclasses with 93.8% of grants classified under F16L (PIPES; Joints OR Fittings FOR PIPES; Supports FOR Pipes, Cables OR Protective TUBING; Means FOR Thermal Insulation IN General). Peak complete grant year is 2020 (5 grants) versus a trough of 1 in 2018. By volume, North sits between Nine Downhole Technologies, LLC and NSK Americas, Inc..
North's three-year grant acceleration
North American Pipe Corporation shows 3 grants in 2022–2024 against only 12 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.
