What this shows ACD's Innovation Score is 35.6/100 (top 49% 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 ACD?

Each dot is one of ACD’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). ACD’s own 18.3 claims/patent is ABOVE the 14.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where ACD's grants concentrate

ACD, LLC is a focused PatentsView assignee: 12 CPC subclasses with 33.3% of grants classified under F04B (Positive-displacement Machines FOR LIQUIDS; Pumps). Peak complete grant year is 2019 (3 grants) versus a trough of 1 in 2016. By volume, ACD sits between ABM Italia S.P.A. and Actega DS GMBH.

ACD's three-year grant acceleration

ACD, LLC shows 2 grants in 2022–2024 against only 3 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.
