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 12.6 claims/patent is at or below the 13.6 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 Hongfa Electric Power Controls Co., Ltd. is a focused PatentsView assignee: 2 CPC subclasses with 88% of grants classified under H01H (Electric SWITCHES; RELAYS; SELECTORS; Emergency Protective Devices). Peak complete grant year is 2024 (11 grants) versus a trough of 1 in 2017. By volume, Xiamen sits between Watts Water Technologies and Zhejiang Jiecang Linear Motion Technology Co., Ltd..

Xiamen's three-year grant acceleration

Xiamen Hongfa Electric Power Controls Co., Ltd. shows 14 grants in 2022–2024 against only 3 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.
