What this shows Zhuhai's Innovation Score is 37.1/100 (top 45% 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 32.9 claims/patent is ABOVE the 11.3 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 Crystal Resonance Technologies Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 100% of grants classified under H03H (Impedance Networks, e.g. Resonant CIRCUITS; Resonators). Peak complete grant year is 2019 (5 grants) versus a trough of 1 in 2021. By volume, Zhuhai sits between Zhengzhou Sanhua Technology & Industry Co., Ltd. and epro GmbH.

Zhuhai's three-year grant acceleration

Zhuhai Crystal Resonance Technologies Co., Ltd. shows 2 grants in 2022–2024 against only 10 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.
