What this shows Amtab's Innovation Score is 27.2/100 (23rd 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 Amtab?

Each dot is one of Amtab’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). Amtab’s own 7.3 claims/patent is at or below the 14.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Amtab's grants concentrate

Amtab Manufacturing Corporation is a focused PatentsView assignee: 6 CPC subclasses with 25% of grants classified under A47C (CHAIRS; SOFAS; Beds). Peak complete grant year is 2021 (7 grants) versus a trough of 1 in 2016. By volume, Amtab sits between Aisin AW Industries Co., Ltd. and Assia Chemical Industries Ltd..

Amtab's three-year grant acceleration

Amtab Manufacturing Corporation shows 6 grants in 2022–2024 against only 13 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.
