Where Shijiazhuang's grants concentrate

Shijiazhuang Tiedao University is a focused PatentsView assignee: 16 CPC subclasses with 33.3% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2016. By volume, Shijiazhuang sits between Shenzhen Xiaoxing Times Technology Co., Ltd. and Shuttle Pharmaceuticals, Inc..

Shijiazhuang's three-year grant acceleration

Shijiazhuang Tiedao University 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.
