Does more volume mean deeper claims for Joong?

Each dot is one of Joong’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). Joong’s own 8.0 claims/patent is at or below the 11.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Joong's grants concentrate

Joong Chenn Industry Co., Ltd. is a focused PatentsView assignee: 2 CPC subclasses with 87.5% of grants classified under A63B (Apparatus FOR Physical Training, Gymnastics, Swimming, Climbing, OR FENCING; Ball GAMES; Training Equipment). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2015. By volume, Joong sits between Joel Ltd. and Jtekt Bearings North America LLC.

Joong's three-year grant acceleration

Joong Chenn Industry Co., Ltd. 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.
