What this shows Xiamen's Innovation Score is 50.5/100 (top 13% 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 15.4 claims/patent is ABOVE the 11.4 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 Kingdomway Group Company is a focused PatentsView assignee: 13 CPC subclasses with 54.5% of grants classified under C12P (Fermentation OR Enzyme-using Processes TO Synthesise A Desired Chemical Compound OR Composition OR TO Separate Optical Isomers From A Racemic Mixture). Peak complete grant year is 2023 (2 grants) versus a trough of 1 in 2017. By volume, Xiamen sits between Wuhan Jingchen Intelligent Identification Technology Co., Ltd. and Xuanwu Hospital Capital Medical University.

Xiamen's three-year grant acceleration

Xiamen Kingdomway Group Company shows 4 grants in 2022–2024 against only 1 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.
