What this shows Xiamen's Innovation Score is 16.8/100 (4th percentile 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 1.7 claims/patent is at or below the 12.3 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 Weco Kitchen and Bath Industry Co., Ltd is a focused PatentsView assignee: 1 CPC subclasses with 14.3% of grants classified under E03C (Domestic Plumbing Installations FOR Fresh Water OR Waste Water ; Sinks). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2024. By volume, Xiamen sits between Xcerion Aktiebolag and Xuzhou Xcmg Excavator Machinery Co., Ltd..

Xiamen's three-year grant acceleration

Xiamen Weco Kitchen and Bath Industry Co., Ltd shows 3 grants in 2022–2024 against only 4 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.
