What this shows Zhuji's Innovation Score is 47.4/100 (top 19% 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 Zhuji?

Each dot is one of Zhuji’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). Zhuji’s own 12.7 claims/patent is at or below the 14.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Zhuji's grants concentrate

Zhuji Itop Hardware Tools Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 63.6% of grants classified under B25B (Tools OR Bench Devices NOT Otherwise Provided FOR, FOR Fastening, Connecting, Disengaging OR Holding). Peak complete grant year is 2024 (5 grants) versus a trough of 1 in 2020. By volume, Zhuji sits between Zee Company and Zumigo, Inc..

Zhuji's three-year grant acceleration

Zhuji Itop Hardware Tools Co., Ltd. shows 8 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.
