What this shows Kunming's Innovation Score is 64.8/100 (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 Kunming?

Each dot is one of Kunming’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). Kunming’s own 8.8 claims/patent is at or below the 16.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

How Kunming's grant cadence moved

Between 2020–2024, Kunming University of Science and Technology received 47 grants versus 1 in 2015–2019 (+4600% equal-window velocity, top decile growth). Across complete PatentsView years, output peaked in 2022 at 14 grants and bottomed in 2018 at 1. Lead class B01D accounts for 29.2% of the portfolio across 60 subclasses. Volume neighbours: Johnstech International Corporation (#5,294) and Neonode Inc. (#5,302).

Kunming's three-year grant acceleration

Kunming University of Science and Technology shows 38 grants in 2022–2024 against only 9 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.
