What this shows Acorn's Innovation Score is 42.0/100 (top 31% 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 Acorn?

Each dot is one of Acorn’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). Acorn’s own 7.6 claims/patent is at or below the 15.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Acorn's grants concentrate

Acorn Engineering Company is a focused PatentsView assignee: 24 CPC subclasses with 13.3% of grants classified under A47K (Sanitary Equipment NOT Otherwise Provided FOR ; Toilet Accessories). Peak complete grant year is 2024 (10 grants) versus a trough of 2 in 2016. By volume, Acorn sits between ecoATM, LLC and Breathe Technologies, Inc..

Acorn's three-year grant acceleration

Acorn Engineering Company shows 17 grants in 2022–2024 against only 19 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.
