What this shows National's Innovation Score is 44.4/100 (top 26% 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.

Where National's grants concentrate

National Machine Company is a focused PatentsView assignee: 28 CPC subclasses with 47.6% of grants classified under B21K (Making Forged OR Pressed Metal Products, e.g. Horse-shoes, Rivets, Bolts OR Wheels). Peak complete grant year is 2017 (4 grants) versus a trough of 2 in 2021. By volume, National sits between Mécanique Analytique Inc. and Nicor, Inc..

National's three-year grant acceleration

National Machine Company shows 6 grants in 2022–2024 against only 5 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.
