What this shows National's Innovation Score is 43.2/100 (top 29% 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 10.4 claims/patent is at or below the 14.3 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 Rehabilitation Center is a focused PatentsView assignee: 7 CPC subclasses with 50% of grants classified under A61H (Physical Therapy Apparatus, e.g. Devices FOR Locating OR Stimulating Reflex Points IN THE BODY; Artificial RESPIRATION; MASSAGE; Bathing Devices FOR Special Therapeutic OR Hygienic Purposes OR Specifi). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2015. By volume, National sits between Nanotech Security Corp. and Neomed Institute.

National's three-year grant acceleration

National Rehabilitation Center shows 4 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.
