What this shows Chongqing's Innovation Score is 35.2/100 (top 50% 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 Chongqing?

Each dot is one of Chongqing’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). Chongqing’s own 9.2 claims/patent is at or below the 13.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Chongqing's grants concentrate

Chongqing Ruzer Pharmaceutical Co., Ltd is a focused PatentsView assignee: 26 CPC subclasses with 40.9% of grants classified under C07D (Heterocyclic Compounds). Peak complete grant year is 2016 (7 grants) versus a trough of 1 in 2022. By volume, Chongqing sits between Carl Zeiss Vision GmbH and CoCo Communications Corp..

Chongqing's three-year grant acceleration

Chongqing Ruzer Pharmaceutical Co., Ltd shows 1 grants in 2022–2024 against only 8 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.
