Does more volume mean deeper claims for Autochair?

Each dot is one of Autochair’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). Autochair’s own 19.0 claims/patent is ABOVE the 16.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Autochair's grants concentrate

Autochair Limited is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under A61G (Transport, Personal Conveyances, OR Accommodation Specially Adapted FOR Patients OR Disabled Persons ; Operating Tables OR CHAIRS; Chairs FOR DENTISTRY; Funeral Devices). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2016. By volume, Autochair sits between Austlen Baby Co. and Automotive Technologies International, Inc..

Autochair's three-year grant acceleration

Autochair Limited shows 3 grants in 2022–2024 against only 2 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.
