What this shows Xiamen's Innovation Score is 45.1/100 (top 24% 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 10.0 claims/patent is ABOVE the 8.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Xiamen's grants concentrate

Xiamen Forbetter Sanitary Ware Co., Ltd is a focused PatentsView assignee: 11 CPC subclasses with 86.7% of grants classified under E03C (Domestic Plumbing Installations FOR Fresh Water OR Waste Water ; Sinks). Peak complete grant year is 2022 (5 grants) versus a trough of 1 in 2018. By volume, Xiamen sits between Xenith LLC and Yageo Corporation.

Xiamen's three-year grant acceleration

Xiamen Forbetter Sanitary Ware Co., Ltd shows 8 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.
