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 1.0 claims/patent is at or below the 16.9 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 Worthfind Industrial Co., Ltd. is a focused PatentsView assignee: 0 CPC subclasses . Peak complete grant year is 2019 (5 grants) versus a trough of 1 in 2024. By volume, Xiamen sits between Xamarin Inc. and Yamo Pharmaceuticals LLC.

Xiamen's three-year grant acceleration

Xiamen Worthfind Industrial Co., Ltd. shows 1 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.
