Does more volume mean deeper claims for Yangtze?

Each dot is one of Yangtze’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). Yangtze’s own 8.6 claims/patent is at or below the 17.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Yangtze's grants concentrate

Yangtze University is a focused PatentsView assignee: 28 CPC subclasses with 50% of grants classified under C09K (Materials FOR Miscellaneous Applications, NOT Provided FOR Elsewhere). Peak complete grant year is 2023 (10 grants) versus a trough of 2 in 2018. By volume, Yangtze sits between Wireless Future Technologies Inc. and Aiphone Co., Ltd..

Yangtze's three-year grant acceleration

Yangtze University shows 27 grants in 2022–2024 against only 11 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.
