What this shows Yanshan's Innovation Score is 64.7/100 (top 2% 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 Yanshan?

Each dot is one of Yanshan’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). Yanshan’s own 7.6 claims/patent is at or below the 15.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

How Yanshan's grant cadence moved

Between 2020–2024, Yanshan University received 63 grants versus 6 in 2015–2019 (+950% equal-window velocity, top decile growth). Across complete PatentsView years, output peaked in 2023 at 22 grants and bottomed in 2017 at 1. Lead class B25J accounts for 15.4% of the portfolio across 82 subclasses. Volume neighbours: Valtech Cardio Ltd. (#4,540) and Bizerba SE & Co. KG (#4,548).

Yanshan's three-year grant acceleration

Yanshan University shows 52 grants in 2022–2024 against only 12 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.
