Does more volume mean deeper claims for Tung?

Each dot is one of Tung’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). Tung’s own 4.7 claims/patent is at or below the 15.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Tung's grants concentrate

Tung TZU Industrial Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 44.4% of grants classified under A47D (Furniture Specially Adapted FOR Children). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2018. By volume, Tung sits between Trimax Safety Corporation and TZU CHI University.

Tung's three-year grant acceleration

Tung TZU Industrial Co., Ltd. shows 5 grants in 2022–2024 against only 0 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.
