Where Wooshin's grants concentrate

Wooshin Industries Co., Ltd is a focused PatentsView assignee: 11 CPC subclasses with 30% of grants classified under H01M (Processes OR Means, e.g. Batteries, FOR THE Direct Conversion OF Chemical Energy Into Electrical Energy). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2020. By volume, Wooshin sits between WG Security Products, Inc. and Wuxi Petabyte Technologies Co., Ltd..

Wooshin's three-year grant acceleration

Wooshin Industries Co., Ltd shows 3 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.
