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.
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 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.
