What this shows American's Innovation Score is 43.8/100 (top 27% 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 American?

Each dot is one of American’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). American’s own 17.1 claims/patent is ABOVE the 14.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where American's grants concentrate

American Piledriving Equipment, Inc. is a focused PatentsView assignee: 16 CPC subclasses with 84.6% of grants classified under E02D (FOUNDATIONS; EXCAVATIONS; Embankments ; Underground OR Underwater Structures). Peak complete grant year is 2016 (6 grants) versus a trough of 1 in 2015. By volume, American sits between Agri-Cover, Inc. and Areva NC.

American's three-year grant acceleration

American Piledriving Equipment, Inc. 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.
