How North's grant cadence moved

Between 2020–2024, North University OF China received 34 grants versus 9 in 2015–2019 (+278% equal-window velocity, above median growth). Across complete PatentsView years, output peaked in 2023 at 13 grants and bottomed in 2015 at 1. Lead class C05G accounts for 10.5% of the portfolio across 69 subclasses. Volume neighbours: Metrologic Instruments, Inc. (#5,958) and Ovonyx Memory Technology, LLC (#5,966).

North's three-year grant acceleration

North University OF China shows 25 grants in 2022–2024 against only 12 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.
