What this shows Xiamen's Innovation Score is 39.4/100 (top 38% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

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 9.3 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 Axent Corporation Limited is a focused PatentsView assignee: 16 CPC subclasses with 45.5% of grants classified under E03D (Water-closets OR Urinals With Flushing DEVICES; Flushing Valves Therefor). Peak complete grant year is 2024 (4 grants) versus a trough of 1 in 2020. By volume, Xiamen sits between World View Enterprises Inc. and Xergy Inc..

Xiamen's three-year grant acceleration

Xiamen Axent Corporation Limited shows 8 grants in 2022–2024 against only 6 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.
