Where National's grants concentrate

National Service Alliance—Houston LLC is a focused PatentsView assignee: 9 CPC subclasses with 96.8% of grants classified under F04B (Positive-displacement Machines FOR LIQUIDS; Pumps). Peak complete grant year is 2021 (9 grants) versus a trough of 7 in 2020. By volume, National sits between Nissin Electric Co., Ltd. and Nevermind Capital LLC.

National's three-year grant acceleration

National Service Alliance—Houston LLC shows 15 grants in 2022–2024 against only 16 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.
