Where Ningbo's grants concentrate

NingBo Poolstar Pool Products Co., Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 80% of grants classified under E04H (Buildings OR Like Structures FOR Particular PURPOSES; Swimming OR Splash Baths OR POOLS; MASTS; FENCING; Tents OR Canopies, IN General). Peak complete grant year is 2023 (2 grants) versus a trough of 1 in 2022. By volume, Ningbo sits between NightBalance B.V. and Ningbo Hengbo Telecommunication Co., Ltd..

Ningbo's three-year grant acceleration

NingBo Poolstar Pool Products Co., Ltd. shows 4 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.
