Where Beijing's grants concentrate

Beijing Sevenstar Flow Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 100% of grants classified under G05D (Systems FOR Controlling OR Regulating Non-electric Variables). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2018. By volume, Beijing sits between Beijing Hengxiang Hongye Foundation Reinforcement Technology Co., Ltd. and Beijing Unicorn Technology Co., Ltd..

Beijing's three-year grant acceleration

Beijing Sevenstar Flow Co., Ltd. shows 3 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.
