What this shows Adams's Innovation Score is 34.7/100 (48th percentile 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 Adams?

Each dot is one of Adams’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). Adams’s own 10.0 claims/patent is at or below the 16.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Adams's grants concentrate

Adams Mfg. Corp. is a focused PatentsView assignee: 19 CPC subclasses with 25.8% of grants classified under A47C (CHAIRS; SOFAS; Beds). Peak complete grant year is 2017 (9 grants) versus a trough of 2 in 2018. By volume, Adams sits between Ardyne Holdings, Limited and Allergan Pharmaceuticals International Limited.

Adams's three-year grant acceleration

Adams Mfg. Corp. shows 2 grants in 2022–2024 against only 10 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.
