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.
