What this shows Powertek's Innovation Score is 33.2/100 (44th percentile of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Powertek?

Each dot is one of Powertek’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Powertek’s own 6.3 claims/patent is at or below the 12.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

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.
