Where Ningbo's grants concentrate

Ningbo Dongchuan Swimming Pool Equipment Co., Inc. is a focused PatentsView assignee: 3 CPC subclasses with 18.2% 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 2024 (7 grants) versus a trough of 1 in 2018. By volume, Ningbo sits between Nexxspan Healthcare, Llc and Northeast Petroleum University.

Ningbo's three-year grant acceleration

Ningbo Dongchuan Swimming Pool Equipment Co., Inc. shows 7 grants in 2022–2024 against only 2 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.
