Where Powertek's grants concentrate
Powertek Hardware Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 66.7% of grants classified under E05B (LOCKS; Accessories THEREFOR; Handcuffs). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2020. By volume, Powertek sits between Popicorns E-commerce Co., Limited and Powwow Energy, Inc..
Powertek's three-year grant acceleration
Powertek Hardware Co., Ltd. shows 4 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.
