What this shows National's Innovation Score is 38.1/100 (top 42% 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 11.1 claims/patent is at or below the 14.8 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 Flooring Equipment, Inc. is a focused PatentsView assignee: 14 CPC subclasses with 50% of grants classified under B24C (Abrasive OR Related Blasting With Particulate Material). Peak complete grant year is 2023 (4 grants) versus a trough of 1 in 2020. By volume, National sits between Nanotech Industrial Solutions and NaturalMotion Ltd..

National's three-year grant acceleration

National Flooring Equipment, Inc. shows 7 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.
