Does more volume mean deeper claims for Xiamen?

Each dot is one of Xiamen’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). Xiamen’s own 4.3 claims/patent is at or below the 14.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Xiamen's grants concentrate

Xiamen Zhoulong Sporting Goods Co., Ltd. is a focused PatentsView assignee: 2 CPC subclasses with 12.5% of grants classified under A63B (Apparatus FOR Physical Training, Gymnastics, Swimming, Climbing, OR FENCING; Ball GAMES; Training Equipment).

Xiamen's three-year grant acceleration

Xiamen Zhoulong Sporting Goods Co., Ltd. shows 3 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.
