What this shows KUN's Innovation Score is 35.9/100 (top 48% 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 KUN?

Each dot is one of KUN’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). KUN’s own 8.6 claims/patent is at or below the 8.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where KUN's grants concentrate

KUN Shan University is a focused PatentsView assignee: 31 CPC subclasses with 28.6% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2016 (5 grants) versus a trough of 1 in 2017. By volume, KUN sits between Kobelco Cranes Co., Ltd. and Kaminario Technologies Ltd..

KUN's three-year grant acceleration

KUN Shan University shows 1 grants in 2022–2024 against only 4 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.
