What this shows Guangdong's Innovation Score is 38.8/100 (top 40% 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.
Guangdong Jiamei Ceramics Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 60% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). By volume, Guangdong sits between GTI Solutions International LLC and Guangdong Meizhi Precision-manufacturing Co., Ltd..
Guangdong Jiamei Ceramics Co., Ltd. shows 4 grants in 2022–2024 against only 0 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.
