What this shows Shenzhenshi's Innovation Score is 41.7/100 (top 32% 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 Shenzhenshi?

Each dot is one of Shenzhenshi’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). Shenzhenshi’s own 15.7 claims/patent is ABOVE the 8.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Shenzhenshi's grants concentrate

Shenzhenshi Yuzhan Precision Technology Co., Ltd. is a focused PatentsView assignee: 12 CPC subclasses with 16.7% of grants classified under B24B (Machines, Devices, OR Processes FOR Grinding OR Polishing ; Dressing OR Conditioning OF Abrading SURFACES; Feeding OF Grinding, Polishing, OR Lapping Agents). Peak complete grant year is 2018 (4 grants) versus a trough of 2 in 2024. By volume, Shenzhenshi sits between Shenzhen Zhiying Technologies Co., Ltd. and Shilat Optronics Ltd..

Shenzhenshi's three-year grant acceleration

Shenzhenshi Yuzhan Precision Technology Co., Ltd. shows 2 grants in 2022–2024 against only 0 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.
