What this shows Zopoise's Innovation Score is 30.4/100 (34th 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 Zopoise?

Each dot is one of Zopoise’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). Zopoise’s own 3.0 claims/patent is at or below the 15.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Zopoise's grants concentrate

Zopoise Technology (ZHUZHOU) Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 25% of grants classified under F21V (Functional Features OR Details OF Lighting Devices OR Systems THEREOF; Structural Combinations OF Lighting Devices With Other Articles, NOT Otherwise Provided FOR). Peak complete grant year is 2022 (5 grants) versus a trough of 1 in 2024. By volume, Zopoise sits between Zenrin Co., Ltd. and Zero E Technologies, LLC.

Zopoise's three-year grant acceleration

Zopoise Technology (ZHUZHOU) Co., Ltd. shows 8 grants in 2022–2024 against only 7 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.
