What this shows National's Innovation Score is 46.5/100 (top 21% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for National?

Each dot is one of National’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). National’s own 7.3 claims/patent is at or below the 16.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where National's grants concentrate

National Diversified Sales, Inc. is a focused PatentsView assignee: 13 CPC subclasses with 35.7% 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 2022 (3 grants) versus a trough of 1 in 2015. By volume, National sits between Nutcracker Therapeutics, Inc. and Neurasignal, Inc..

National's three-year grant acceleration

National Diversified Sales, Inc. shows 7 grants in 2022–2024 against only 2 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.
