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 20.0 claims/patent is ABOVE the 15.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

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.
