What this shows Zhongce's Innovation Score is 19.7/100 (6th 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 Zhongce?

Each dot is one of Zhongce’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). Zhongce’s own 1.4 claims/patent is at or below the 3.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Zhongce's grants concentrate

Zhongce Rubber Group Co., Ltd. is a focused PatentsView assignee: 2 CPC subclasses with 14.3% of grants classified under B60C (Vehicle TYRES; Tyre INFLATION; Tyre CHANGING; Connecting Valves TO Inflatable Elastic Bodies IN GENERAL; Devices OR Arrangements Related TO Tyres). By volume, Zhongce sits between Zhejiang Qili Health Technology Ltd. and Zitara Technologies, Inc..

Zhongce's three-year grant acceleration

Zhongce Rubber Group Co., Ltd. shows 1 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.
