Where Foshan's grants concentrate

Foshan Naibao Electric Co., Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 18.2% of grants classified under F04D (NON-POSITIVE-DISPLACEMENT PUMPS). Peak complete grant year is 2019 (6 grants) versus a trough of 1 in 2016. By volume, Foshan sits between Forever Bulb, Llc and Gavish-galilee BIO Applications, Ltd.

Foshan's three-year grant acceleration

Foshan Naibao Electric Co., Ltd. shows 2 grants in 2022–2024 against only 6 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.
