What this shows Qinghai's Innovation Score is 39.8/100 (top 37% 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 Qinghai?

Each dot is one of Qinghai’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). Qinghai’s own 5.2 claims/patent is at or below the 14.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Qinghai's grants concentrate

Qinghai Normal University is a focused PatentsView assignee: 8 CPC subclasses with 83.3% of grants classified under Y02D (Climate Change Mitigation Technologies IN Information AND Communication Technologies [ICT], I.E. Information AND Communication Technologies Aiming AT THE Reduction OF Their OWN Energy USE). Peak complete grant year is 2023 (3 grants) versus a trough of 1 in 2022. By volume, Qinghai sits between Quickstyle Industries, Inc. and Quantifoil Instruments GmbH.

Qinghai's three-year grant acceleration

Qinghai Normal University shows 6 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.
