Where Nanjing's grants concentrate

Nanjing Zgmicro Company Limited is a focused PatentsView assignee: 9 CPC subclasses with 55.6% of grants classified under H04W (Wireless Communication Networks). Peak complete grant year is 2024 (5 grants) versus a trough of 1 in 2021. By volume, Nanjing sits between Nyse American LLC and NanoMech, Inc..

Nanjing's three-year grant acceleration

Nanjing Zgmicro Company Limited shows 7 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.
