Does more volume mean deeper claims for TON?

Each dot is one of TON’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). TON’s own 18.8 claims/patent is ABOVE the 7.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where TON's grants concentrate

TON DUC Thang University is a focused PatentsView assignee: 27 CPC subclasses with 50% 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 2021 (5 grants) versus a trough of 1 in 2015. By volume, TON sits between Tohoku Electric Power Company, Inc. and Toyox Co., Ltd..

TON's three-year grant acceleration

TON DUC Thang University shows 2 grants in 2022–2024 against only 8 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.
