What this shows Chongqing's Innovation Score is 23.8/100 (13th 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 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 6.2 claims/patent is at or below the 14.5 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 University of Technology is a focused PatentsView assignee: 8 CPC subclasses with 50% of grants classified under G01D (Measuring NOT Specially Adapted FOR A Specific VARIABLE; Arrangements FOR Measuring TWO OR More Variables NOT Covered IN A Single Other SUBCLASS; Tariff Metering APPARATUS; Measuring OR Testing NOT OT). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2018. By volume, Chongqing sits between Chips Unlimited, Inc. and ChromaCon AG.

Chongqing's three-year grant acceleration

Chongqing University of Technology shows 1 grants in 2022–2024 against only 2 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.
