Does more volume mean deeper claims for Nottingham?

Each dot is one of Nottingham’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). Nottingham’s own 20.1 claims/patent is ABOVE the 9.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Nottingham's grants concentrate

Nottingham Spirk Design Associates is a focused PatentsView assignee: 5 CPC subclasses with 57.1% 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).

Nottingham's three-year grant acceleration

Nottingham Spirk Design Associates shows 2 grants in 2022–2024 against only 1 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.
