What this shows Chongqing's Innovation Score is 66.0/100 (top 1% 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 8.0 claims/patent is at or below the 17.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

How Chongqing's grant cadence moved

Between 2020–2024, Chongqing University received 71 grants versus 13 in 2015–2019 (+446% equal-window velocity, top decile growth). Across complete PatentsView years, output peaked in 2023 at 28 grants and bottomed in 2019 at 1. Lead class Y02P accounts for 12.3% of the portfolio across 120 subclasses. Volume neighbours: Andrew Wireless Systems GmbH (#3,467) and FCI USA LLC (#3,475).

Chongqing's three-year grant acceleration

Chongqing University shows 65 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.
