What this shows Zhengzhou's Innovation Score is 34.8/100 (49th 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 Zhengzhou?

Each dot is one of Zhengzhou’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). Zhengzhou’s own 11.3 claims/patent is ABOVE the 5.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Zhengzhou's grants concentrate

Zhengzhou Sanhua Technology & Industry Co., Ltd. is a focused PatentsView assignee: 15 CPC subclasses with 86.7% of grants classified under B01F (Mixing, e.g. Dissolving, Emulsifying OR Dispersing). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2023. By volume, Zhengzhou sits between Zensar Technologies Limited and Zhuhai Crystal Resonance Technologies Co., Ltd..

Zhengzhou's three-year grant acceleration

Zhengzhou Sanhua Technology & Industry Co., Ltd. shows 5 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.
