What this shows Zhangzhou's Innovation Score is 46.3/100 (top 21% 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 Zhangzhou?

Each dot is one of Zhangzhou’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). Zhangzhou’s own 8.6 claims/patent is at or below the 9.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Zhangzhou's grants concentrate

Zhangzhou GO WIN Lighting Co., Ltd is a focused PatentsView assignee: 12 CPC subclasses with 50% 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 2023 (5 grants) versus a trough of 3 in 2021. By volume, Zhangzhou sits between Zalman Tech Co., Ltd. and ZIM Aircraft Seating GMBH.

Zhangzhou's three-year grant acceleration

Zhangzhou GO WIN Lighting Co., Ltd shows 9 grants in 2022–2024 against only 3 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.
