What this shows Zhuhai's Innovation Score is 46.4/100 (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 Zhuhai?

Each dot is one of Zhuhai’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). Zhuhai’s own 13.4 claims/patent is ABOVE the 11.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Zhuhai's grants concentrate

Zhuhai Sailner 3D Technology Co., Ltd. is a focused PatentsView assignee: 15 CPC subclasses with 88.2% of grants classified under B33Y (Additive Manufacturing, i.e. Manufacturing OF Three-dimensional [3-D] Objects BY Additive Deposition, Additive Agglomeration OR Additive Layering, e.g. BY 3-D Printing, Stereolithography OR Selective ). Peak complete grant year is 2021 (5 grants) versus a trough of 2 in 2022. By volume, Zhuhai sits between Zeroplus Technology Co., Ltd. and Zoom International a.s..

Zhuhai's three-year grant acceleration

Zhuhai Sailner 3D Technology Co., Ltd. shows 11 grants in 2022–2024 against only 5 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.
