Where Shanghai's grants concentrate

Shanghai Ruiyu Biotech. Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 55.6% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2023 (2 grants) versus a trough of 1 in 2017. By volume, Shanghai sits between Shanghai HUA Hong NEC Electronics Co., Ltd. and Shenzhen Bailinniao Technology Co., Ltd..

Shanghai's three-year grant acceleration

Shanghai Ruiyu Biotech. Co., Ltd. shows 5 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.
