What this shows National's Innovation Score is 48.1/100 (top 17% 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 8.7 claims/patent is at or below the 12.4 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 Disaster Management Research Institute is a focused PatentsView assignee: 17 CPC subclasses with 40% of grants classified under G08B (Signalling OR Calling SYSTEMS; Order TELEGRAPHS; Alarm Systems). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2018. By volume, National sits between Nanocarrier Co., Ltd. and Nevada Research & Innovation Corporation.

National's three-year grant acceleration

National Disaster Management Research Institute shows 6 grants in 2022–2024 against only 2 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.
